Abstract
This thesis presents a method for calibrating regional scale hydrologic models using the
upper South Saskatchewan River watershed as a case study. Regional scale hydrologic
models can be very difficult to calibrate due to the spatial diversity of their land types.
To deal with this diversity, both a manual calibration method and a multi-basin
automated calibration method were applied to a WATFLOOD hydrologic model of the
watershed.
Manual calibration was used to determine the effect of each model parameter on
modeling results. A parameter set that heavily influenced modeling results was selected.
Each influential parameter was also assigned an initial value and a parameter range to be
used during automated calibration. This manual calibration approach was found to be
very effective for improving modeling results over the entire watershed.
Automated calibration was performed using a weighted multi-basin objective
function based on the average streamflow from six sub-basins. The initial parameter set
and ranges found during manual calibration were subjected to the optimization search
algorithm DDS to automatically calibrate the model. Sub-basin results not involved in
the objective function were considered for validation purposes. Automatic calibration
was deemed successful in providing watershed-wide modeling improvements.
The calibrated model was then used as a basis for determining the effect of altering
rain gauge density on model outputs for both a local (sub-basin) and global (watershed)
scale. Four de-clustered precipitation data sets were used as input to the model and
automated calibration was performed using the multi-basin objective function. It was
found that more accurate results were obtained from models with higher rain gauge
density. Adding a rain gauge did not necessarily improve modeled results over the entire
watershed, but typically improved predictions in the sub-basin in which the gauge was
located.

Introduction
1.1 Problem Description
Hydrologic simulation models have been used since 1966 to help hydrologists better
understand different hydrologic processes, describe the hydrology of a specific region,
and to predict the potential hydrologic impact that future development may cause. While
hydrologic models are often useful, accurate model predictions can be difficult to
achieve. Hydrologic modeling software typically requires large quantities of input data
that may necessitate extensive pre-processing before a model can be properly run.
Additionally, the number of unknown parameters in hydrologic models is often large, and
a significant degree of calibration may be required to ensure the model is able to
represent historical and future trends.
For regional scale hydrologic models, data management and calibration can be a
very complex task. The modeled region of interest can contain diverse land types, which
can be difficult to classify and parameterize. Regional scale models can also have
inconsistent and poorly distributed input data (i.e., precipitation, temperature, wind speed,
and humidity). The availability and relative density of weather stations strongly
influences the accuracy estimated rainfall, temperature, etc., between stations. Since these
inputs drive the model, poor data density or interpolation can lead to flawed results.
This thesis presents two contributions to the scientific literature on regional-scale
hydrologic modeling. First, a general approach used for calibration of regional scale
hydrologic models, with application to a WATFLOOD model of the Red Deer River, the
Bow River, and the Old Man River watersheds in Alberta, is presented. In this method, a
structured approach towards manual calibration is initially used to determine parameters
that have a significant influence on model output. This parameter set is then subjected to
automated calibration to optimize parameter values. The objective function used for the
automated calibration is calculated based on the model results from multiple sub-basins.
2
The second component of this study is an investigation into the impacts of de-clustered
precipitation data upon hydrologic model calibration. The goal of this portion of the
study is to determine a relationship between gauge density and a hydrologic model’s
potential to be accurately calibrated.
1.2 Objectives
There are two objectives of this study. The first is to calibrate a regional scale hydrologic
model using both manual calibration and automatic calibration methods. The steps taken
to meet this objective include:
1. Model development and assessing project limitations: The study area and the
pre-calibrated model are assessed with the purpose of determining major study
limitations. Three types of limitations are encountered. The first is caused by
missing historic data. Data sets used to fuel the model (historic precipitation), and
data sets used to evaluate the model (historic streamflows) both have missing data
for portions of the study period. The second limitation is the unknown behavior
of certain man-made hydrologic features within the study area such as dams,
irrigation canals, and reservoirs, and incorporating these features into a
continuous model is outside the scope of this project. The final limitation comes
from WATFLOOD itself. While WATFLOOD is designed to handle many
hydrologic features, not all processes can be modeled and this puts restrictions on
the ability to accurately model portions of the watershed.
2. Manual calibration: This involves trial and error variation of each of the
unknown model parameters with the purpose of determining how each parameter
influences modeling results, and to improve the modeling results. Each parameter
is also given a range based on model sensitivity that is used during automated
calibration. Both subjective visual inspection and a formal objective function are
used for model comparison in this step.
3
3. Automated calibration: The objective function used in this step is designed to
consider the results of multiple sub-basins in the model. Using the parameter set
and ranges obtained through manual calibration, a search algorithm is used to
optimize the objective function and the find calibrated values for each parameter.
The calibration is performed based on the objective function alone and the model
is validated using the results from sub-basins not used in the objective function
calculation.
The second objective of this study is to assess the relationship between rain gauge
density and calibration accuracy. Four models are set up, each with a reduced rain gauge
density. Each model is calibrated using the calibration method used in the first portion of
the study, and impacts of the de-clustered input data sets are discussed and interpreted.
1.3 Site Description
Located mostly in southern Alberta, Canada, the watershed used for this study is the
upper South Saskatchewan River, which consists of the Red Deer River, the Bow River,
and the Old Man River. With a contributing area of over 120,000 km2, these three basins
flow through diverse land types including mountains, foothills, and prairies. The study
area drains from west to east between the Rocky Mountains at the western border of
Alberta (continental divide) and the prairies of western Saskatchewan. Figure 1.1 shows
a satellite image of the study area with an overlay of the boundaries of the watersheds.

Background
This study uses a multiple basin calibration approach to calibrate a regional scale model
comprised of multiple sub-basins and multiple stream gauges. This multiple basin
calibration method has the benefit that it allows a hydrologic model to be efficiently
calibrated when testing the model against rain gauge density alterations and de-clustering.
This chapter is dedicated to providing a background on both the techniques and
tools used to complete this study. The literature review (section 2.1) provides a
background on hydrologic modeling, calibration of hydrologic models, and methods for
interpolating and de-clustering rain gauge data. This chapter also provides a brief
summary of the WATFLOOD hydrologic modeling software (section 2.2).
2.1 Literature Review
2.1.1 Hydrologic Modeling
Hydrologic modeling is an attempt to represent different aspects of the hydrologic cycle
through statistical and/or mathematical simulation. It is a powerful tool that can be used
for both research purposes and for planning and development (Seth, 2004). Software
codes capable of simulating several parts of the hydrologic cycle are sometimes used to
represent an entire hydrologic system. Although the understanding of the hydrologic
cycle continues to improve, there is still much to be learned on how hydrologic systems
function, and how they can be better modeled to meet the needs of today’s researchers
and practitioners.
Computer-based hydrologic modeling started during the 1960’s when large
computer models were used to attempt to match historical hydrologic data. The ability to
7
perform many calculations using the computer was helpful for answering complicated
hydrologic questions.
The first computational hydrologic model was created at Stanford University and
was called the Stanford Watershed Model (Crawford & Linsley, 1966). It was able to
effectively simulate precipitation, evaporation, evapotranspiration, infiltration, surface
runoff, ground water flow, and streamflow (Bedient & Huber, 2002). The goal of these
earlier programs was to continuously simulate hydrologic processes and to include all of
the interacting processes in the same model structure (Crawford & Burges, 2004).
Since the development of these early computer-based hydrologic models, there have
been several types of software of varying complexity developed to assist hydrologists in
understanding complex hydrologic processes. As a result of continued advancement,
hydrologic modeling remains a key component of the advancement of hydrologic study.
Often, the development and calibration of hydrologic models gives insight into the
limitations of modeling specific hydrologic processes and leads to improvements in
modeling software. Additionally, increased computing power has created a demand for
more field data, which in turn allows for further hydrologic study. If applied correctly,
hydrologic models are currently the best way to estimate and understand complex
hydrologic systems (Bedient & Huber, 2002). There are many types of hydrologic
models, but the three most used types are: conceptual, stochastic, and physically-based
models.
Conceptual hydrologic models use very little information about the watershed, and
provide efficient estimates of how a watershed will respond to precipitation (Fenicia et
al., 2007). Some examples of conceptual hydrologic models are linear models, Nash
instantaneous unit hydrograph, the rational method, and kinematic or dynamic wave
methods for overland flow (Bedient & Huber, 2002).
Stochastic hydrologic models use mathematics and statistics to produce an output
based on a set of input data. A typical example of this would be producing synthetic
streamflows based on a set of input precipitation data based on historical statistics from
the specific watershed (Bedient & Huber, 2002).
8
Physically-based hydrologic models attempt to simulate the hydrologic processes as
they occur in the real world and are based on our understanding of the physics of
individual hydrologic processes, e.g., infiltration, snowmelt, etc. (Seth, 2004).
Physically-based distributed models can be applied to many types of hydrologic problems
(Seth, 2004). Some common inputs for a physically based hydrologic model include
precipitation, temperature, wind speed, humidity, and initial snow depth. These are used
as input parameters to mass transfer and energy budget equations that can be used to
model snow melt, evaporation, and infiltration (Bedient & Huber, 2002).
Physically-based hydrologic models are typically set up to be single event models
or continuous models. Single event models are primarily used for the design of hydraulic
systems to handle large floods based on a single extreme precipitation event. They are
convenient in that it is easy to set up the antecedent conditions in the system, and because
they have very short run times. Continuous models are long term simulations that usually
simulate several historic precipitation events. These can range from a single season to
many years. Like single event models, continuous models can also be used in the design
of hydraulic systems, but may also include simulation goals related to base flow
depletion/recharge, evaporation, or snow melt as these hydrologic processes take much
longer than would be simulated by a single event model.
2.1.2 Calibration of Hydrologic Models
Most hydrologic models contain general equations that are intended to be useful over a
large variety of geographic areas. These equations include parameters that can be varied
to account for the hydrology of a specific study area. Without calibration, such “general-
purpose” models will not likely produce accurate, acceptable results (Debo & Reese,
2002). This is partly because the equations intended to represent natural hydrologic
processes contain parameters and coefficients that are difficult if not impossible to
estimate from field data. Once a hydrologic model has been set up to represent the
diversity of the specified, model calibration can begin.
9
Calibration of a hydrologic model is the process by which parameters that heavily
influence model output are modified in an attempt to replicate the model outputs with
historic data from the watershed (Debo & Reese, 2002). For example, it is often
desirable for the model to be able to simulate historic streamflow data given historic
precipitation data. Depending on the purpose of the model, the requirements for
calibration may vary: one model may be intended to best meet peak flows, another may
be focused on simulating low or mid flows. The goals of calibration are typically
expressed in terms of a calibration objective function defined such that the optimal
solution is that with the smallest (or largest) objective function.
There are several objective functions that can be used to assess the accuracy of a
hydrologic model. The objective function selected may depend on the specific goals of
the study. The most common objective function used for calibration of hydrologic
models is the Nash-Sutcliffe model efficiency coefficient (Nash & Sutcliffe, 1970)
defined as:

)(
)(1 (2.1)
where Qo is observed discharge and Qm is modeled discharge. The coefficient is a
measure of the model’s predictive ability. The Nash-Sutcliffe model efficiency
coefficient has a range of -∞ to 1.0. The maximum value of 1.0 indicates a perfect match
between the model and the observed data. A value of 0.0 indicates that the model is as
good of a predictor as the mean of the observed flows. A value greater than 0.0 means
that the model is a more accurate predictor than the mean of the observed data, while a
value less than 0.0 results when the model is a less accurate prediction than the mean of
the observed data.
While the Nash-Sutcliffe model efficiency coefficient is one of the most common
methods for evaluating the accuracy of a hydrograph, it has been shown that very poor
models can possess relatively high Nash-Sutcliffe coefficients, and low Nash-Sutcliffe
10
coefficients can result from a good model. Because of this, it is beneficial not to
conclude on the performance of a model based on the Nash-Sutcliffe coefficient alone
(Jain & Sudheer, 2008).
Once an objective function is selected, the calibration process can be executed using
either manual calibration or automated calibration. Manual calibration is a method in
which parameters are manually varied one at a time in an attempt to improve the model
results and gain an understanding of how certain parameters influence model outputs.
Automated calibration is a method where parameters are simultaneously varied using a
search algorithm to find the parameter set that produces the most accurate model results.
Manual calibration is the most widely used method to calibrate hydrologic models
(Boyle et al., 2000). Usually used in the early stages of the calibration of a hydrologic
model (prior to automated calibration), it is a method that essentially uses trial-and-error
parameter adjustment to improve the model and determine a good parameter set (Madsen,
2000).
Often, the comparison between the observed hydrograph and the simulated
hydrograph is made purely from visual inspection. Experienced modelers can obtain
very accurate models through manual calibration, but without an objective function, it is
difficult to quantify its quality in comparison to equally plausible models (Madsen,
2000). If automated calibration is to take place following manual calibration, it can be a
good idea to monitor the selected objective function during manual calibration so that a
better understanding can be gained of how that objective function is reacting to visual
improvements in the model.
Manual calibration provides modelers with some advantages over automated
calibration. Because parameters are varied one at a time, modelers see each varied
parameter changes model outputs. This allows a modeler to determine the set of
dominant parameters that strongly influence the specific watershed. Through this
process, a modeler is also able to understand the sensitivity of each parameter and
determine reasonable starting points and ranges for the parameter set to be used during
automated calibration; this will reduce the number of iterations required during
11
automated calibration. Modelers that manually calibrate their models gain a better
understanding about how different hydrologic processes impact the output hydrographs.
Additionally, these modelers are better prepared to identify problems that may be
encountered during automated calibration (Madsen, 2000).
Though popular and useful, manual calibration has drawbacks. Each model run
requires visual hydrograph analysis (and possibly objective function calculation) and
parameter adjustment by the modeler, and makes manual calibration a labor intensive
process. The method can be complicated, and expertise from one modeler is difficult to
pass on to another modeler as the best method for improving one’s manual calibration
skill is through hands on experience and training (Boyle et al., 2000).
An increasingly popular method of improving the quality of hydrologic models is
automated calibration; however, because automated calibration approaches often require
a mathematical background and use more complicated computational tools than manual
calibration, it still remains unused by many modelers (Boyle et al., 2000). Each
parameter varied in automated calibration must be given a range defined by maximum
and minimum values. The set of specified parameter ranges is called the parameter
space. Automated calibration uses optimization algorithms to search the parameter space
to find the parameter set that will result in the best value of the objective function. The
technique is not labor intensive, nor is it biased by the modeler’s expert knowledge or
opinions (Madsen, 2003), except in the selection of the objective function and parameter
ranges.
Three things are necessary to complete an automated calibration: an objective
function, a parameter set with an initial parameter space, and an optimization algorithm.
As previously discussed, there are different objective functions to choose from. Properly
selecting an objective function that meets the needs of the specific study is critical for
developing a model that meets the needs of the modeler. It has been found that
performing a single criteria approach to automated calibration can lead to good curve
fitting, but can lead to a parameter set that is hydrologically unrealistic (Boyle et al.,
2000). A method that can help to avoid this situation is to complete in-depth manual
12
calibration prior to automated calibration to see that there are hydrologically realistic
parameter values.
The final component of an automated calibration is an optimization algorithm. For
this, there are many to choose from, which can be categorized as either local or global
search methods. Both local and global search methods are used for computationally
complex problems in which no specific algorithm can be used to solve the problem in its
entirety (MacFarlane & Tuson, 2008). While both methods may start searching from the
same point in the parameter space, local search methods will improve the result of the
objective function towards a local maximum (or local minimum) value. Global search
methods are designed to solve optimization problems that may have multiple optima
(Zabinsky, 1998).
Because rainfall runoff models can have numerous locally optimal solutions within
the parameter space (Duan et al., 1993), local search methods will often not produce a
global optimum because the results will depends on the search starting point. Because of
this, global search methods should be employed to solve hydrologic calibration problems
(Madsen, 2000). Some of the most popular methods for automated calibration are
evolution-based searches such as the shuffled complex evolution (Duan et al., 1993) and
genetic algorithms (Wang, 1991). Several studies (Duan et al., 1993; Gan & Biftu, 1996;
Cooper et al., 1997; Kuczera et al., 1997; Franchini et al., 1998; Thyer et al., 1999) have
compared genetic algorithms and shuffled complex evolution (SCE), and find that the
SCE algorithm is more effective and efficient. It has been widely used in conceptual
rainfall runoff models (Madsen, 2000).
The optimization algorithm chosen for this study is a dynamically dimensioned
search (DDS) (Tolson & Shoemaker, 2007). The DDS algorithm is novel and simple
stochastic single-solution based heuristic global search algorithm (Tolson & Shoemaker,
2007). With a purpose of finding good global solutions instead of globally optimal
solutions, the algorithm is designed to scale the search to the user-specified number of
function evaluations (Tolson & Shoemaker, 2007). Initially, the algorithm searches
globally, and as the number of specified objective function evaluations approaches, the
13
search becomes more localized (Tolson & Shoemaker, 2007). To interact with a
hydrologic model DDS requires a parameter set with pre-determined user-assigned
ranges for each parameter.
DDS has been compared to the SCE method, and has been shown to require only
15-20% of the model evaluations used by the SCE method to obtain equally good values
of the objective function (Tolson & Shoemaker, 2007).
2.1.3 Temporal and Spatial Data Interpolation Methods
The most important input to a hydrologic model is the temporal and spatial distribution of
rainfall (Lynch & Schulze, 1995; Yoo, 2002). The output of a regional scale model with
sparse rainfall data can be strongly influenced by the interpolation routine that generates
rainfall values for unmeasured areas of the watershed, and having an accurate areal
precipitation representation is crucial in hydrologic modeling (Dorninger et al., 2008).
Selecting a method to estimate rainfall distribution from rain gauges can often be a time
consuming but important problem (Lynch & Schulze, 1995).
In regional scale models with complex terrain, properly using the available data is
an important aspect of developing an accurate model (Dorninger et al., 2008). Rainfall
interpolations for regional scale models are effected by the distribution and density of
rain-gauges as this can significantly contribute to the sampling error in the estimation of
the total volume of rainfall over a given area (Yoo, 2002). Beven and Hornberger (1982)
found that, for predicting streamflow hydrographs, the correct assessment of rainfall
input volume is more important that the spatial rainfall pattern.
While a majority of this study is dedicated to the calibration of a regional scale
model, once complete, the calibration method is tested using several rain-gauge input
data sets. Input data sets are generated by interpolating precipitation input sets that
decrease in density with each subsequent trial. Though the method of interpolation is not
14
varied to generate these data sets, it is a key aspect of this study and as such must be
selected carefully.
Many techniques exist that modelers use to estimate rainfall between rain gauge
point measurements. Common techniques include: inverse distance interpolation,
Shepard’s weighted interpolation, Schafer interpolation, SACLANT interpolation, and
Kriging (Lynch & Schulze, 1995).
Inverse distance weighting (IDW) is determined according to the following
equations (Shepard, 1968):

∑=

(2.3)
where d is the distance between the location (x,y) where rainfall is unknown and the
given weather station (i), and F is the value of rainfall at the given weather station.
Shepard’s method employs the same weighting function, but only within a certain radius;
otherwise the weighting function is equal to zero. The radius should be selected based on
the geographic density of the data points (gauge density), and should be chosen so that
each sample radius includes at least five sample points (Yoeli, 1975).
Schafer interpolation makes use of the assumption that daily rainfall distribution
similarly resembles median monthly rainfall distribution (Lynch & Schulze, 1995). The
daily rainfall measurements from each rain gauge station are transformed into a
percentage of the median monthly rainfall at that station for that specific data (Schafer,
1991). Those values are interpolated using a two dimensional interpolation technique
onto a rectangular grid (SACLANT, 1979). The interpolated values are then multiplied
by the gridded median monthly rainfall values to result in daily rainfall estimates (Dent,
Lynch and Schulze, 1988).
15
SACLANT interpolation is another two dimensional interpolation used for a
rectangular-gridded shaped study area, such as that used in the WATFLOOD software.
Values are initially assigned to each unknown point in the rectangular grid and then an
iterative process is performed where the unknown values are altered (improved) until the
surface of the precipitation values has obtained a targeted value of smoothness through
the known data points (SACLANT, 1979).
The Kriging method of interpolation uses a semi-variogram model to interpolate a
set of points (ArcInfo, 1991). The semi-variogram is a function that represents the
expected difference in value between sample points based on a given radius and
orientation (Clark, 1979). This model can be altered to be spherical, circular,
exponential, Gaussian, linear, universal linear or universal quadratic. A study
investigating the influence of different semi-variogram models (Lynch & Schulze, 1995)
found the universal linear model to produce the lowest root mean square errors when
attempting to interpolate known rainfall data. Statistical methods like Kriging can be
optimal in a statistical sense but are not applicable to some studies (Ahrens, 2005).
It has been found that for a regional scale models with a strong climactic gradient
and a sparse data set that IDW and Kriging are the most efficient towards generating a
model that can produce accurate hydrographs when calibrated (Ruelland et al., 2008).
The IDW method was found to be a significantly less time consuming process relative to
Schafer, SACLANT, and Kriging (Lynch & Schulze, 1995), and is the method selected
for this study.
2.1.4 De-Clustering
While it has been found that varied rain-gauge density can have very little effect on
modeling results in regions with relatively high rain-gauge densities (Allen &
DeGaetano, 2005), this study focuses on a region with a sparse, poorly distributed data
set. For this study, rain-gauge density will be decreased using the de-clustering method
16
described in this section, and the impacts on hydrologic model calibration will be
assessed.
De-clustering is a term used to describe a method in which data points are removed
to reduce the known, unknown, or estimated negative effects of clustered data to obtain a
data set that is more representative of underlying data (Smith, Goodchild, Longley,
2006). While several methods for de-clustering data exist, the technique has not been
extensively studied in the context of hydrologic modeling. Ahrens (Ahrens, 2005) found
a slight improvement using de-clustering for one of four rain gauge densities evaluated.
The method used by Ahrens (Ahrens, 2005) selected the closest pair of rain gauges and
eliminated the gauge which had the next closest rain gauge to it. For this study, de-
clustering will be performed using a search that will calculate a “clustering index” for
each rain gauge as follows:
∑=
=N
iidCI
1
2 (2.4)
where di is the distance between the selected rain gauge and the closest neighboring rain
gauge and N is the number of neighboring rain gauges used to calculate CI. For each rain
gauge, di is calculated for the closest four neighboring rain gauges and the gauge with
lowest CI is removed and the process is repeated. An example study area is shown below
in figure 2.1. In this example, the x-y locations of the rain gauges, labeled Xi, are shown
in table 2.1.

Table 2.2 shows the CI calculated using the lowest four distance squared values for
each rain gauge. The gauge selected through this method was gauge X5 with a CI of 28.
That gauge would be removed from the interpolation, and if further de-clustering was
desired, the process would be repeated, but starting with the updated gauge distribution.

2.2 Watflood
The hydrologic model used for the study is WATFLOOD. It is a physically-based
routing model combined with a conceptual hydrologic simulation model (Kouwen, 2007).
In WATFLOOD, a watershed is divided into a Cartesian grid, and each grid square is
subdivided into one or more land use types based on satellite imagery. The behavior of
each assigned land class is then governed by the equations of conceptual hydrologic
models and the land class parameters of WATFLOOD (section 2.2.2). An example of
how a specific grid square is handled is shown in figure 2.2.
Figure 2.2 – Group response unit and runoff routing concept (Donald, 1992; Kouwen,
2007)
In figure 2.2, the grid square is allocated in to land types (A, B, C, D) based on the
satellite image, and each land type is handled in the model as a separate watershed. The
runoff from each of the individual land class models is added to the physically based
streamflow routing model (Kouwen, 2007).
19
WATFLOOD simulates only a subset of the physical processes occurring in nature,
but includes: infiltration, evaporation, snow accumulation, interflow, base flow, and
overland channel routing (Kouwen, 2007).
2.2.1 Model Requirements
The WATFLOOD model used for this calibration is essentially fuelled by just two
hydroclimatic inputs: temperature and rainfall. Each of these inputs is taken from historic
data sets, and unknown data points (grid cells) are interpolated. Additionally, each grid
cell requires information to describe the specific land it represents including (Kouwen,
2007):
N – Grid cell number
NEXTI – Receiving cell number. This tells WATFLOOD which grid cell the streamflow will be sent to.
XX, YY – Grid cell location from bottom left corner of grid.
DA– Drainage area in km2.
IBN – River class
1,2,…N – Fractions in each land cover type.
The model requires parameter assignment for both the land type and river class
parameters (described in section 2.2.2) as well as values for the initial conditions of both
snow depth and streamflow, all of which can be modified in the WATFLOOD input files.
2.2.2 Model Parameters
While directly measured meteorological data is used to fuel the model, model behavior
heavily relies on the values of many adjustable system parameters. The primary
parameters driving the model results may be divided into land class parameters, which
20
are dictated by land use and soil type, and river class parameters, which are dictated by
drainage area, geographic location, and sub-basin boundaries. The default values listed
with each parameter shown are not considered WATFLOOD specific defaults, but are
simply the defaults arrived at in this study.
There are five river class parameters. The first two are related to how
WATFLOOD handles base flow:
LZF – Lower zone function (default = 0.200 x 10-5)
PWR – Exponent on lower zone function (default = 0.200 x 101)
Both LZF and PWR effect base flow the depletion function (QLZ) according to the
following equation:
PWRLZSLZFQLZ *= (2.5)
where LZS is the lower zone storage in each grid cell and QLZ is the lower zone flow
(base flow). All land classes present in each grid (except impervious) contribute to the
lower zone storage.
There are two river roughness parameters:
R1 – Flood plain roughness coefficient (default = 0.200 x 101)
R2 – River channel roughness coefficient (default = 0.100 x 101)
Both R1 and R2 are transformed to values of Manning’s n and then subject to
Manning’s equation to determine the average channel velocity:
21
32
SRnk
V h= (2.6)
where k is a conversional constant, n is the Gaucklet-Manning coefficient, Rh is the
hydraulic radius, and S is the slope of the water surface.
21
MNDR – Meander factor (default = 0.100 x 101)
The meander factor is a ratio of how long each channel in the grid is relative to the
length of the grid.
The parameters related to land use are as follows:
• DS – Depression storage (mm) (default = 0.200 x 102)
• DSFS – Depression storage for snow (mm) (default = 0.200 x 102)
• RE – Interflow depletion coefficient (default = 0.302 x 10)
• AK – Soil permeability for bare ground (default = 0.904 x 101)
• AKFS – Soil permeability under snow (default = 0.140 x 102)
• RETN – Upper zone specific retention (default = 0.750 x 102)
• AK2 – Upper zone resistance factor for bare ground (default = 0.125 x 10)
• AK2FS – Upper zone resistance factor under snow (default = 0.984 x 10)
• R3 – Overland roughness for bare ground (default = 0.101 x 102)
• R3FS – Overland roughness under snow (default = 0.394 x 102)
• R4 – Impervious area roughness (default = 0.100 x 102)
• CH – Channel efficiency factor (default = 0.900 x 10)
• MF – Melt factor (mm/°C/hr) (default = 0.139 x 10)
• BASE – Base melt temperature (°C) (default = -0.115 x 101)
• RHO – Snow density (relative to rho H20) (default = 0.333 x 10)
• FTAL – Forest vegetation coefficient (default = 0.850 x 10)
Not all parameters described above will have a significant effect on modeling
results. Depending on the specific model, certain parameters can strongly influence
different portions of the model. The entire parameter set will be analyzed for
significance during manual calibration; however, not all parameters will be adjusted
during automated calibration.

Chapter 3
Model Development & Calibration
Properly calibrating a hydrologic model is an essential step towards using that model as a
basis for experimentation and understanding. While many methods of calibration can be
used to improve the accuracy a model’s outputs, no method can guarantee the most
accurate model possible; in fact, it is likely that no ‘best’ solution exists and that several
equally accurate models can be produced with very different parameter sets (Beven,
2000).
Parameters that affect the behavior of the entire model are sometimes determined
through the calibration of only one sub-basin. For local scale models, this can be very
effective since many parameters are not likely to vary significantly through the basin.
However, due to variation of land types of a regional scale model, calibrating parameters
one sub-basin at a time is less likely to produce a parameter set that represents the
behavior of the entire watershed; therefore, multi-basin calibration approaches are
needed. The calibration method described this chapter is performed on a regional scale
model. It promotes parameter determination through an objective function that is
calculated from the results in multiple sub-basins.
The following sections review the development of the hydrologic model for the
Upper South Saskatchewan River case study, as well as model calibration as it applies to
WATFLOOD hydrologic models. Section 3.1 outlines the model development and data
analysis that was performed prior to calibration. This includes the model discretization,
gauge locations, available data sets, and study limitations. Section 3.2 provides a
description of the manual calibration process. This section includes a description of the
objective functions used, sub-basin selection methods, a description of the parameters
used for calibration and how they affect model outputs, an example manual calibration
for a single sub-basin, and a summary of the calibration results. Section 3.3 outlines the
steps taken during automated calibration. These include a brief overview of the
23
optimization algorithm, a summary of the parameters selected and their optimization
ranges, a description of the objective function weighting method, an overview of the sub-
basins used for the automated process, and a summary of the automated calibration
results.
3.1 Upper South Saskatchewan River Model Development
Before model calibration can begin, the study area and the available historic data must be
understood. This section provides an overview how the study area has been represented
using a WATFLOOD hydrologic model, a summary of the data sets available for the
study, and a review of some limitations that were encountered during model
development.
3.1.1 Study Area & Model Discretization
The watershed used for this study is the Upper South Saskatchewan River. Located in
southern Alberta, Canada, this watershed is made up of three major rivers: the Red Deer
River, the Bow River, and the Old Man River. The watershed has a contributing area of
over 120,000 km2 and flows east from the continental divide. For the purpose of
developing a regional scale hydrologic model of the watershed, the study area has been
divided up into 1341 grid cells, each with an area of approximately 100 km2 (10 km x 10
km). Figure 3.1 shows a map of the study area, while Figure 3.2 shows the gridded form
of the study area.

Each grid cell must have a designated river class, and must be assigned one or more
land uses. Using a combination of satellite imagery, sub-basin boundaries, and
contributing area, three river classes were designated. The three river classes are:
Class 1 – Mountain/Foothills stream (contributing area < 1000 km2 and visually
identifiable as a region with high vegetation from satellite imagery)
Class 2 – Prairie stream (contributing area < 1000 km2 and visually identifiable
as a region with low vegetation from satellite imagery)
Class 3 – Major River (contributing area > 1000 km2)
Figure 3.3 shows the assigned river classes for each grid cell.

For this study, land use was divided into nine land classes: dense forests, light
forests, mixed forests, open, wetlands, agriculture, glacier, water, and impervious. Each
land class was assigned using remotely sensed land cover data (Kouwen, 2007). Figure
3.4 shows the distribution of each land class in the watershed.

As shown, a majority of the land use (86%) in the watershed is characterized as
agricultural or open land.
The model is set up to output streamflows at 30 grid cell outflow points in the
model which roughly corresponds to the 30 sub-basin stream gauges that exist in the
watershed and are shown on figure 3.5. The modeled (and measured) drainage areas and
land use for each sub-basin is shown in table 3.1.

3.1.2 Gauge Locations & Available Data Sets
For this study, the hydrologic model has been set up to simulate continuously from
January 1, 2002 to December 31, 2005. This study utilized historic data from 30 stream
gauges (Environment Canada, 2007a) and 28 weather stations (Environment Canada,
2007b). Stream gauge data are in the form of average daily flow from each stream. Each
stream gauge provides data for the corresponding sub-basin and is located at the outlet of
a grid cell.
The available historic streamflow data from each stream gauge determine which
sub-basins should be used for calibration. The available stream gauge data are shown in
table 3.2.

3.2 Manual Calibration
This section provides an outline of how manual calibration was performed on a
WATFLOOD model of the Upper South Saskatchewan River watershed. The purpose of
manual calibration is to determine a finite set of parameters that strongly influences
modeling outputs. These parameters will be manually adjusted to values that result in
significant improvements in model outputs. Selecting the influential parameter set and
31
determining an initial value for each parameter through manual adjustment reduces the
parameter set and parameter space to be used for automated calibration and may produce
more accurate results. Described here are the objective functions used during manual
calibration, the method used for selecting sub-basins to calibrate, a description of the
most relevant and sensitive parameters that control model outputs, sensitivity of
calibrated parameters, and results obtained from manual calibration.
3.2.1 Objective Function
The objective function used for manual calibration (and later automated calibration) is the
Nash-Sutcliffe model efficiency coefficient (Nash & Sutcliffe, 1970). The general form
of this equation is:

where Qot is the observed discharge and Qm
t is the modeled discharge for the time period
t. Either daily flows or monthly average flows were used as a basis for model
comparison. For the daily coefficient, the daily peak flows were used for Qo and Qm, and
for the monthly coefficient, the average of the daily peak flows for each month were used
for Qo and Qm.
In addition to the daily and monthly Nash-Sutcliffe model efficiency coefficients,
visual hydrograph inspections were performed to determine the effect of each parameter
on model outputs. Since the study does not aim to compare calibration results found
using different objective functions, no other measures will be used.
32
3.2.2 Sub-basins Selected for Calibration
Each time a parameter was varied, the objective function was calculated for certain sub-
basins and visual inspection of the hydrographs was performed. Prior to any parameter
variation, the most appropriate sub-basins were selected for the purpose of learning the
most from each parameter variation.
Throughout the calibration process, results from certain sub-basins are used to
calibrate the model, while others are used for model validation. Validating the model is a
process in which results from some sub-basins that were not used to measure model
performance are compared to confirm model improvements. Limitations encountered in
this study restricted the number of sub-basins that could be trusted for calibration or
validation. Before sub-basin selection could take place, it was important to recognize and
address the limitations this case study. Here, these limitations can be classified into three
categories: data limitations, limitations caused by man-made hydraulic features,
hydrologic modeling limitations.
Data Limitations
While the streamflow data set contains historic measurements from 30 stream
gauges, it is clear from table 3.2 that the data set is not complete. Of the 30 stream gauge
locations, only 13 contain daily data for the entire study period. One gauge has no data
available for the study period, and several others are missing entire years of
measurements. The remaining gauges have only summer data, which can still be useful
for model validation purposes. The limited data set must be considered when selecting
basins for calibration (section 3.2.2).
Man-made Hydraulic Features
One portion of the study area is heavily affected by man-made reservoirs and
irrigation canals. Sub-basin three (see figure 3.5) is the watershed of the Little Bow
River and has a drainage area of approximately 6,800 km2. Of that area, drainage from
the upper 4,230 km2 is diverted into Travers Reservoir, and only 30 % of the annual
33
drainage is released back into the Little Bow River (Atlas of Alberta Lakes, 2005). The
other 70% of the drainage is diverted into Little Bow River Lake which feeds irrigation
canals for the region. Since the drainage released to the Little Bow River is controlled
and depleted rather than naturally drained, the model output from this sub-basin, which
only considers environmental influences, can not be used for calibration. Since this sub-
basin makes up over 20% of the drainage area for Oldman River watershed (sub-basin 2),
modeling results from the Oldman River are not useful for calibration.
Hydrologic Modeling Limitations
Hydrologic modeling limitations are the modeling software’s inability to represent
certain hydrologic processes. Here, the major hydrologic modeling limitation is the
simplification of processes simulated on prairie agricultural land use. Fifty-nine percent
of the entire watershed is allocated as agricultural use, most of which is located in the
prairie region of the study area. Two aspects of prairie hydrology make hydrologic
modeling on a regional scale extremely difficult. First, blowing snow can transport up to
75% of annual snow fall from open fields (Fang et al., 2007). This leads to varied snow
melt patterns due to drifts, and lengthens spring runoff. This phenomenon is not
simulated with WATFLOOD. Second, because much of the prairies contain glacially
formed depressions many basins are internally drained. The runoff from internally
drained basins contributes to pools that are formed in these glacial depressions. From
there, water either infiltrates or evaporates. Only during the most extreme runoff events
will these pools spill over and contribute to streamflow (Fang et al., 2007). The model
could not be setup to simulate these hydrologic processes because of limitations with the
WATFLOOD software. Because these two aspects of prairie hydrology are not
simulated with WATFLOOD, calibration of sub-basins dominated by the agricultural
land use is limited in this study. The agricultural land class parameters are not used
during the initial manual calibration process; however, they are altered to improve
modeling results once the other land class parameters have been estimated through
manual calibration.
34
A second hydrologic modeling limitation in this study is the presence of glaciers in
the mountains that lie along the western portion of the study area. Though they make up
a very small percentage of any sub-basin (15% maximum), streamflow in watersheds that
contain glaciers tends to be dominated by their summer melt cycles. WATFLOOD holds
a limitation on initial snow depth at 8850 mm (8.85 m). This is not a high enough value
for a glacier, as the snow cover should be effectively infinite for the purposes of
modeling. If the glacier land class was assigned an initial snow depth of 8.85 m, the
snow would melt off during the first spring, and the glaciers would no longer contribute
to streamflow in the model as they would in reality. For this reason, several basins that
contain significant glaciers (>5%) are not used in model calibration or validation.
The goal of initial sub-basin selection was to remove sub-basins with flawed or
incomplete data sets. For the selection of sub-basins used during manual calibration, sub-
basins with complete sets of streamflow data are desired. Additionally, sub-basins that
are dominated by a certain land class are determined. When a sub-basin is dominated by
a specific land class, the modeling results are heavily reliant on those land class
parameters. For example, sub-basin 25 is the best candidate for calibrating the dense
forest land class parameters (63% coverage – table 3.1). Starting with the default values,
dense forest land class parameters could be calibrated using sub-basin 25, and then the
parameter values would be applied basin-wide.
The land class parameters chosen for manual calibration were dense forest, light
forest, mixed forest, and open land. These were selected because they represent the
largest portion of the study area that is not dominated by different prairie drainage
phenomenon. Agricultural land class parameters are calibrated as well, but because of
unpredictable prairie hydrology, they were manually adjusted last and while considering
the results from several sub-basins at a time. Considering the agricultural land class
parameters last prevents the unpredictable behavior of prairie hydrology from producing
parameter values that have poor accuracy throughout the entire watershed. Instead,
knowing that the hydrology is unpredictable, the agricultural parameter values are
adjusted last. These adjustments will be for the purpose of improving the objective
function and not necessarily to represent the hydrology of a specific sub-basin’s
35
agricultural land use (which is known to be unpredictable and geographically diverse).
The sub-basins selected for manual calibration are shown in table 3.3.

Figure 3.7: Sub-basins selected for manual calibration
36
As shown above, the sub-basins are diverse in drainage area, but not in geographic
location as the southern portion is not well represented in manual calibration. The
presence of Travers Reservoir in the southern portion of the study area controls and
diverts too much water for model results to be considered relevant.
It is important to note that, while only the sub-basins shown above have been
selected for manual calibration, results from other sub-basins are also compared to gauge
data for validation purposes.
3.2.3 Calibrated Parameters
First, a sensitivity analysis was performed on all model parameters, and then only
sensitive parameters were subjected to manual calibration. To determine which
parameters should be calibrated, it is important to understand the function each parameter
serves within the model. This section summarizes the parameters that were found
through trial and error to have a significant effect on model outputs when altered.
River Class Parameters
Starting with the pre-calibrated model (all parameter values set to defaults as
described in section 2.2.2) each parameter was varied one at a time (+ 25%) and the
model was run. After each model run, the daily Nash-Sutcliffe coefficient was calculated
and the hydrograph of a specific basin was visually analyzed. Visual analysis combined
with parameter descriptions (Kouwen, 2007) helped determine how each parameter
altered the modeling of each hydrologic process in WATFLOOD. Often, the visual
analysis was challenging since changes in the hydrographs were small and difficult to
decipher, which is why the objective function value was also as a primary tool during
manual calibration. The sub-basin used for this initial sensitivity was sub-basin nine, and
had an initial daily Nash-Sutcliffe coefficient of -0.096. Table 3.4 contains a list of river
class parameters, the parameter variation for the sensitivity trial, the objective function
changes that resulted from parameter variation, and how it influences the hydrologic
37
model. Each parameter was varied from their respective default values (described in
section 2.2.2).
Table 3.4: River class parameter initial sensitivity and hydrograph impacts for sub-basin
nine

R1 + 25% 0.011 magnitude and timing of peak flowR2 + 25% 0.044 magnitude and timing of peak flow
MNDR + 25% 0.023 magnitude and timing of peak flow
The river class parameters all produced measurable differences in the daily Nash-
Sutcliffe coefficients. Only one parameter was removed from the manual calibration as a
result of the river class sensitivity analysis, and it was R1. Even though adjustments of
R1 produced measurable hydrograph changes, this process showed that both R2 and
MNDR influence the model in the same fashion as R1 and thus it was eliminated as a
calibration parameter.
Land Class Parameters
Land class parameters are analyzed in the same manner as river class parameters,
but are considered separately for the purpose of selecting a parameter set that represents
all of the significant hydrologic and hydraulic functions that influence the model. The
land class parameters that were considered during the initial portion of manual calibration
are described in section 2.2.2. Table 3.5 contains a list of land class parameters, the
parameter variation for the sensitivity trial, the objective function changes that resulted
from parameter variation, and how it influences the hydrologic model.

There are several parameters that have little to no effect on the modeling results
(DS, DSFS, AK, AKFS, R3, R3FS, R4, CH, and RHO) and were removed from the
manual calibration process. Of the seven remaining land class parameters that had a
higher impact on modeling results (RE, RETN, AK2, AK2FS, MF, BASE, and FTAL), the
RE, AK2, and AK2FS parameters were observed to have the same effect on the output
hydrographs. Since RE had a more significant effect on the daily Nash-Sutcliffe
coefficient, it was retained for the manual calibration and AK2 and AK2FS were removed
from the list of parameters to be further calibrated.
The parameters that were considered for further calibration were: LZF, PWR, R2,
MNDR, MF, BASE, RE, RETN, FTAL.
3.2.4 Manual Calibration Steps
This section outlines the method used during manual calibration. Using sub-basin nine as
an example, the parameters selected for manual calibration in section 3.2.3 are varied in a
specific order to improve the accuracy of the modeling results.
39
Starting with the pre-calibrated model the hydrograph and daily Nash-Sutcliffe
coefficient were analyzed for a specific basin. One of the sub-basins used during manual
calibration was sub-basin nine. A comparison of measured vs. modeled results with
default parameter values for sub-basin nine is shown in figure 3.8.

Figure 3.8: Measured streamflows vs. modeled streamflows from pre-calibrated model of
Red Deer River below Burnt Timber Creek (sub-basin 9)
The modeled hydrograph consistently predicted flows that were less than the
measured values. This was a result of both the magnitude of peak flows, and the shape of
the base flow depletion curves. The Nash-Sutcliffe daily coefficient for the pre-
calibrated sub-basin was -0.096. A general algorithm used to improve the hydrograph
manually for each sub-basin is described as follows:
1. Set initial parameters (default values) for all calibrated parameters
2. Run model and identify visually analyze for strengths and weaknesses in
the output hydrographs (magnitude of peak flows, etc)
40
3. Adjust base flow parameters (LZF, PWR) to improve the base flow
depletion curve using both visual hydrograph analysis and the results of
the objective function
4. Adjust streamflow parameters (R2, MNDR) to improve timing of peak
flows using both visual hydrograph analysis and the results of the
objective function
5. Focusing on the initial melt portions of the model outputs, adjust the snow
melt parameters (MF, BASE) to improve the timing and magnitude of the
peak flows resulting from snow melt using both visual hydrograph
analysis and the results of the objective function
6. Adjust remaining parameters (RE, RETN, FTAL) to improve magnitude of
all peak flows (those influenced by snow melt included) using primarily
the results of the objective function
Steps 2 – 6 were performed iteratively using small parameter adjustments to ensure
that certain land class parameters were not adjusted to hydrologically unrealistic values to
compensate for inadequacies in the default parameter values of other land classes.
The purpose of visual hydrograph inspection was that particularly in the early
stages of manual calibration, adjusting parameters that vary the timing of peak flows and
base flow depletion (LZF, PWR, R2, MNDR, MF, and BASE) sometimes lead to an
improved objective function, but a model that is further away from a reasonable
representation of historic hydrographs when visually inspected. The objective function is
not a perfect measure of model performance, and visual inspections help to ensure that
modeling improvements occur when the objective function improves as sometimes the
opposite can be the case. Since RE, RETN, and FTAL did not alter the timing of the
hydrographs they were manually adjusted using objective function results only (though
intermittent visual observations were still made to for validation). Adjusting only the
parameters selected in section 3.2.3 the manually calibrated hydrograph for sub-basin 9
41
produced a daily Nash-Sutcliffe coefficient of 0.738. The hydrograph is shown in figure

While the monthly Nash-Sutcliffe coefficient was not considered during calibration,
it was used as a form of validation for the calibrated model. The monthly Nash-Sutcliffe
coefficient improved from -0.026 to 0.893.
The process of manual calibration was performed on each of the sub-basins shown
in table 3.3, each time focusing on the land and river class parameters that dominate those
basins respectively (shaded values). To complete the process of manually calibrating
four river class parameters for three river types, and five land class parameters for five
land types required approximately 2500 model runs.

3.2.5 Calibration Results
Manual calibration was performed on land class and river class parameters that had
significant effects on the sub-basins listed in table 3.3. Outputs from several sub-basins
with incomplete data sets were considered for the purpose of model validation.
Additionally, while the performance metric of the Nash-Sutcliffe monthly coefficient was
not used directly as a measure of accuracy, it was compared for the pre-calibrated and
manually calibrated models to provide another measure of model accuracy. The
parameter values found through manual calibration for each river class and land class
parameter described in section 3.2.3 are shown in table 3.6 and 3.7 respectively.

To determine the success of manual calibration, results from sub-basins that were
not used to manually calibrate the model (sub-basins not in table 3.3) were considered.
Though these sub-basins did not have complete data sets, their Nash-Sutcliffe coefficients
were calculated by comparing only the data available with modeling results. The pre-
calibrated and manually calibrated values for the Nash-Sutcliffe daily and monthly
coefficients are shown in table 3.8. Shaded rows indicate sub-basins used to manually

Though not all sub-basins were used during the manual calibration process, model
accuracy was improved for almost all cases. Since the calibrated parameters influence
modeling results watershed-wide, adjusting a parameter value to improve the results of
one sub-basin can change (hopefully improve but possibly degrade) modeling results in
other sub-basins. The model’s accuracy was improved for 15 of 19 sub-basins (7 of 9
validation sub-basins) for the daily Nash-Sutcliffe coefficient, and for 19 of 19 sub-basins
(9 of 9 validation basins) for the monthly Nash-Sutcliffe coefficient through automated
calibration. The average of both the Nash-Sutcliffe daily and monthly values also
increased significantly through manual calibration. Although the average values of the
objective function may not be the best way to evaluate the success of all hydrologic
calibrations it is effective in this case since each sub-basin (with the exception of sub-
basin 1) is a head water basin and is considered independently of all others. Another
option for comparing watershed-wide success would be a weighted average of the Nash-
Sutcliffe coefficients using sub-basin area, rainfall, streamflow, or another measure as the
weighting function. The objective function is weighted by average streamflow during the
automated calibration in the following section.
44
3.3 Automated Calibration
The purpose of using an automated algorithm to calibrate the model was to refine some
of the estimated parameter values found from manual calibration to improve model
results. While manual calibration was used to identify important parameters, automated
calibration searches the parameter space of some of those parameters to find the best
solution within the given parameter ranges. This section provides an outline of how the
manually calibrated model was improved using automated calibration. The method uses
an objective function that is calculated using the results from multiple sub-basins in each
trial. Described in this section is a brief description of the optimization algorithm
selected for this study, an outline of the parameter ranges used, the objective function
used, the selection of sub-basins, and results.
3.3.1 Optimization Algorithm (DDS)
The optimization algorithm chosen for this study is the dynamically dimensioned search
(DDS) (Tolson & Shoemaker, 2007). For DDS to function with WATFLOOD, it
requires a model parameter set, and the corresponding parameter ranges in terms of
maximum and minimum values. The DDS manual (Tolson & Seglenieks, 2007)
recommends that for optimization problems involving 10 or more parameters that 1000
function evaluations can typically generate reasonable results, so that will be the value
used for this study. Details on the specifics of the DDS algorithm can be found in
(Tolson & Shoemaker, 2007).
3.3.2 Parameter Selection & Parameter Ranges
The parameters selected for automated calibration are chosen with a goal of representing
the major hydrologic processes that heavily influence modeling results. Through the
manual calibration the dominant processes were found to be: snow melt, base flow
45
depletion, evapotranspiration, streamflow rates, evaporation, and interflow. The
parameters selected to represent each process are shown in table 3.9:
Table 3.9: Automated calibration parameters selected by hydrologic process
Hydrologic Process ParametersSnow Melt MF, BASEBaseflow Depletion LZFEvapotranspiration RETNStream Flow Rates R2Evaporation FTALInterflow RE
Each process was assigned one parameter for automated calibration except for snow
melt. For snow melt, two parameters were selected since both MF and BASE have
significantly different effects on the output hydrographs. Both PWR and MNDR were not
included in the automated calibration process because they influence the output
hydrographs in a very similar manner to LZF and R2 respectively, but less significantly
(table 3.4).
Initially, the range of each parameter was chosen as approximately +/- 50% of the
value obtained from manual calibration as long as that range does not exceed the
reasonable boundaries for the parameter which are governed by hydrologic and physical
limitations (i.e. MNDR cannot be less than 1). For BASE an initial range was selected as
+/- 1.5 degrees, and for FTAL, initial ranges were selected as +/- 0.2 (minimum of 0.01,
and maximum of 1.0).
Following each automatic calibration trial, the ranges for each parameter were reset
according to the results of the trial. Figure 3.10 depicts a decision diagram outlining how
parameters were adjusted after each trial.

3.3.3 Objective Function Weighting Method

calculation.
47
3.3.4 Sub-basin Selection
The sub-basins selected for automatic calibration were not the same set selected for
manual calibration. The purpose of this was to increase the number of sub-basins that
could be used as validation sub-basins to gain more information about the success of the
weighted objective function. The sub-basins used for the automated calibration objective
function calculation are selected from the sub-basins listed in table 3.3. The sub-basins
were chosen to represent all major land classes, and represent a variety of geographic
areas so that the automated algorithm calibrates to an objective function that represents
historic data from a variety of regions within the watershed. The sub-basins were also
chosen to have a full historic streamflow data set for the simulation period (January 1,
2002 to December 31, 2005). The sub-basins used in automated calibration are shown in

Figure 3.11: Sub-basins used for automated calibration
The simulation outputs (streamflow) from the six selected sub-basins are subjected
to the daily Nash-Sutcliffe coefficient, and then incorporated into the weighted objective
function (equation 3.2) using a script called “MultiNash” (Appendix B). Although a
small portion of the watershed is represented during automated calibration, results from
several other basins will be considered for validation purposes once the calibration
process is complete.
3.3.5 Automated Calibration Results
Automated calibration was performed using the iterative process described in figure 3.10.
Although the model is calibrated using the results from the six sub-basins listed in table
3.10, model validation is considered for all sub-basins with acceptable data (table 3.8).
The manually calibrated model had a weighted (using sub-basins in table 3.10) Nash-
Sutcliffe daily coefficient of 0.669. This weighted Nash-Sutcliffe daily coefficient was
improved through the automated process to 0.743. The parameter values found through
49
the automated calibration process for each river class and land class parameter described
in section 3.2.3 are shown in table 3.11 and 3.12 respectively.

The automatic calibration was done using the weighted objective function as a
measure of model accuracy, and the parameter values found were applied across the
entire basin. Although the weighed objective function improved through automated
calibration, the success of the method is measured by considering modeling
improvements from the individual sub-basins in the model. Additionally, the Nash-
Sutcliffe monthly coefficients are used as performance metric since the automated
process measures considered only the daily measurements. The Nash-Sutcliffe daily and
monthly coefficients resulting from automated calibration are compared to the manually
calibrated values for all acceptable basins in table 3.13. Shaded rows indicate sub-basins
that were automatically calibrated.

Although only six sub-basins were automatically calibrated, improvements were
made in the Nash-Sutcliffe daily and monthly coefficients in most cases. Automated
calibration improved the model accuracy for 15 of 19 sub-basins (9 of 13 validation sub-
basins) for the daily Nash-Sutcliffe coefficient, and for 14 of 19 sub-basins (8 of 13
validation sub-basins) for the monthly Nash-Sutcliffe coefficient. Although the weighted
average showed improvement, the method is validated by the improvement of the basins
that were not considered during the automated calibration.
Finally, the pre-calibrated model results were compared to the fully calibrated
(automated) results. The Nash-Sutcliffe daily and monthly coefficients resulting from
automated calibration were compared to the pre-calibrated model for all acceptable

The automated calibration using a multi-basin approach produced improved
modeling results relative to pre-calibrated results in 17 of 19 sub-basins for the daily
Nash-Sutcliffe coefficient and 19 of 19 sub-basins for the monthly Nash-Sutcliffe

3.4 Summary
The Upper South Saskatchewan River watershed was modeled in WATFLOOD and
calibrated to a daily Nash-Sutcliffe coefficient using both manual and automated
calibration. Figure 3.12, 3.13, and 3.14 display hydrographs from the pre-calibrated
model and those produced by manual and automated calibration respectively for sub-
basin 9.

Calibration was successful in that manual calibration produced improved modeling
results in 15 of 19 sub-basins for the daily Nash-Sutcliffe coefficient and 19 of 19 sub-
basins for the monthly Nash-Sutcliffe coefficient. Automated calibration using a multi-
basin approach produced improved modeling results relative to manually calibrated
results in 15 of 19 sub-basins for the daily Nash-Sutcliffe coefficient and 14 of 19 sub-
basins for the monthly Nash-Sutcliffe coefficient. The automated calibration using a
multi-basin approach produced improved modeling results relative to pre-calibrated
results in 17 of 19 sub-basins for the daily Nash-Sutcliffe coefficient and 19 of 19 sub-
basins for the monthly Nash-Sutcliffe coefficient.
The approach was very effective in improving modeling results over the entire
watershed, producing consistent improvements in almost all of the sub-basins used for
validation. There are several potential improvements that could be made to improve the
calibration. First, more parameters could be included in the automatic calibration
process. Although this would provide the opportunity for a more accurate model, but it
54
might come at the cost of increased computational time as more model evaluations might
be required to ensure a sufficient solution has been found.
A second possible way to improve the calibration of this model would be to alter
the weighting function used for the automated calibration or to change the sub-basins
used in the calculation of “MultiNash.” Though this would not guarantee improved
modeling results, it would give insight into how the weighting function and sub-basin
selection can impact automatic calibration.

Chapter 4
Impacts of Precipitation De-clustering
The first portion of this thesis dealt with hydrologic model calibration using both manual
and automated calibration methods. This chapter applies the automatic calibration
methodology to four models, each with a precipitation data set that has been reduced
from the original set used in chapter 3. The first goal of this chapter is to determine how
removing specific rain gauges from the precipitation data set affected the calibration
potential of hydrologic models on both the local (sub-basin) and global (regional scale
watershed). The results of this study will not only provide information on the effects of
removing precipitation data, it is intended to provide insight into the potential to improve
hydrologic models by increasing the number and/or density of available meteorological
stations. Results from areas of the watershed with different spatial distributions of
precipitation gauges are also analyzed in an attempt to determine a relationship between
rain-gauge density and calibrated Nash-Sutcliffe coefficients.
The second goal of this portion of the study was to observe how parameter values
vary from the “optimum” values found from calibrating the model described in chapter 3.
Comparing how each parameter varies when the precipitation inputs are changed will
reveal how uncertainty in precipitation translates to potential uncertainty in different
parameter values.
The rain gauge data set that was used to produce the input precipitation data for the
model was reduced several times through a de-clustering method. Each time the rain
gauge set was reduced, a new input data set was interpolated (using equation 2.2 and 2.3)
and the model was re-calibrated using the method outlined in Chapter 3.
The results of this study will help to determine how removing precipitation data
points impacts hydrologic modeling calibrations. It will help to determine areas of
regional scale hydrologic models that require more precipitation gauges and areas that
56
can have use a reduced data set without significantly decreasing the accuracy of modeling
results.
4.1 De-clustering Method
De-clustering is the process of removing data points in an effort to improve the spatial
distribution of the data. De-clustering of the precipitation data reduces rain gauge density
and provides a rain gauge set that is used to create a new interpolation to be used as an
input data set.
4.1.1 Rain Gauge Removal Order
Starting with a set of rain gauges that included all 28 gauges in the study area, a
clustering index was calculated using a variation on the nearest neighbour removal order
(Ahrens, 2005) according to:
∑=
=N
iidCI
1
2 (4.1)
where CI is the clustering index, di is the distance between the selected rain gauge and the
closest neighboring rain gauge and N is the number of neighboring rain gauges used to
calculate CI. For each rain gauge, di is calculated for the closest N (4 for this study)
neighboring rain gauges and the gauge with lowest CI is removed and the process is
repeated. An example of how CI values would be calculated is shown in section 2.1.4.
The order of removal of the 28 rain gauges according to equation 4.1 is shown in
table 4.1.
57
Table 4.1 – Rain gauge removal order
Gauge CI17 1.36E+031 2.14E+0322 3.91E+0314 4.09E+0313 5.62E+039 6.50E+0319 6.55E+0327 9.68E+0310 1.02E+046 1.34E+0426 1.35E+0411 1.76E+048 2.36E+047 3.82E+0412 4.21E+0428 5.80E+0424 8.07E+0421 9.68E+0415 1.35E+053 1.78E+0520 1.98E+0525 3.06E+054 4.71E+0523 9.06E+05
2 N/A16 N/A5 N/A18 N/A
The final four gauges (2, 16, 5, and 18) listed above do not have a clustering index
because at least four other gauges are required for this calculation.
4.1.2 De-clustering Trials
De-clustering of the initial rain gauge set was done four times. Each trial removed five
rain gauges (including those removed in previous trials). Table 4.2 shows summarizes
the gauges removed each step.
58

The rain gauge sets were interpolated to generate precipitation data for each grid
cell according to the IDW interpolation method outlined in section 2.1.3 (equation 2.2
and 2.3), with a maximum search radius implemented according to Shepard’s method
(Yoeli, 1975). The search radius selected for this interpolation was 100 km, and the
minimum number of points required for the interpolation was 1.
The locations of the rain gauges used in the complete set (used for calibration in
chapter 3) are compared to the rain gauge sets used in the de-clustering trials in figure 4.1

4.2 Calibration Results
Once the interpolation for the rain gauge set was complete, the model was run with the
new precipitation interpolations used as the input data set. The parameter values for this
first model run were the final parameter values from the automated calibration (Table
3.11 and 3.12).

As may be expected, the general trend of the pre-calibrated models was a decreased
Nash-Sutcliffe coefficient as the number of rain gauges used to interpolate the input data
was reduced. Starting from each pre-calibrated model, each of the models was calibrated
using automated calibration as described in section 3.3.
Automated calibration identified unique parameter sets for each model with de-
clustered input data sets. Parameter variation was tracked for each river and land class
parameter to determine how they varied from the “optimal” values that were found from
calibration of the complete data set. Figure 4.2 shows the parameter variation of the river
class parameters (LZF and R2) from the de-clustering trials.

Figure 4.2: River class parameter variation resulting from de-clustering trials
The values of LZF and R2 found through automated calibration of the de-clustered
models were all very similar. The river class parameters LZF and R2 control the base
flow depletion curve and the timing of the peak flows. It was expected that these values
would not vary significantly when a de-clustered precipitation set was used as the model
input since they have already been calibrated to match the shape of the base flow
depletion curve (LZF), and the timing of the peak flows (R2) of the historic data set.
They have very little to do with modeled runoff volume which is where most of the
uncertainty in the de-clustered models comes from.
Land class parameters control the magnitude of the peak flows and the volume of
runoff simulated by WATFLOOD. Different interpolations would likely lead to different
volumes of input precipitation, and thus, variation of the land class parameters optimize
the Nash-Sutcliffe coefficients was expected. Figure 4.3 shows the parameter variation
of the land class parameters (RE, RETN, MF, BASE, and FTAL) from the de-clustering
trials.

Figure 4.3: Land class parameter variation resulting from de-clustering trials

Compared to the river class parameters, the de-clustered models produced more
variation in the land class parameter values. The variation of the land class parameters
was within a reasonable range, with all parameters having variation less than one order of
magnitude, and with BASE having no variation more than two degrees Celsius.
The initial and calibrated weighted daily Nash-Sutcliffe coefficients for each trial
are shown in table 4.5.

Although the weighted daily Nash-Sutcliffe coefficients were improved for each
trial through automated calibration, analysis of the results for each sub-basin was
required to determine how precipitation de-clustering impacts modeling results on a local
and global scale. Table 4.6 and 4.7 show the daily and monthly Nash-Sutcliffe
coefficients respectively for each trial for each sub-basin. The shaded values indicate the

Two things to consider are that the results from sub-basins 16-25 had consistently
better daily and monthly Nash-Sutcliffe coefficients with the full precipitation data set
used as a model input. Additionally, the best daily and monthly Nash-Sutcliffe
coefficients for sub-basins 26-29 resulted from models that used de-clustered
precipitation data sets. Figures 4.4 and 4.5 show the average daily and monthly Nash-
Sutcliffe values for each de-clustering trial. Three values are shown: the total average for
each trial, the average value for basin 16-25, and the average value for basins 26-29.

Figure 4.7: Sub-basin 26-29 shown with full precipitation set locations
Sub-basins 16-25 (with the exception of 25) are all located in a region of the
watershed that has a very high density of rain gauges, while sub-basins 26-29 are located
just outside of the same dense region. The sub-basins located within the dense rain gauge
68
region (sub-basins 16-23) produced better modeling results when the entire rain gauge set
was used, and thus, benefited from the proximity of the gauges. The sub-basins located
just outside of the dense region (sub-basins 26-29) were heavily influenced by the
clustered points. When some of those points were removed, the precipitation
interpolations that influence these sub-basins were more balanced and the Nash-Sutcliffe
coefficients were improved.
It is apparent that some of the de-clustering trials produced certain sub-basins where
the best daily and monthly Nash-Sutcliffe values did not correspond to the model with the
most complete input data set; however, a majority of sub-basins were best represented by
the model developed with a full precipitation data set. On a global scale, the full
precipitation set produced a model with the highest average daily and monthly Nash-
Sutcliffe values.
4.3 Discussion
The primary findings resulting from the work outlined in this chapter is the relationship
between rain gauge density and calibrated model results on a local and global scale. It
was found that watershed-wide (globally), modeling results were more accurate when
more rain gauges were used for the model input. There were, however, geographic areas
of the model (local) that had improved modeling results when a de-clustered data set was
used as the input. This section discusses potential interpretations and implications of
results of the calibrations described in this chapter.
On a global scale, the results are quite straight forward to interpret. The average
Nash-Sutcliffe values of each de-clustering trial show that models with more input data
produced more accurate modeling results upon calibration. This supports the theory that
more input data will produce regional scale models with stronger predictive abilities over
the entire watershed.
69
On a local scale, the results shown in this chapter are more complex. Since some
sub-basins had the best Nash-Sutcliffe coefficients from de-clustered models, the results
require more interpretation. It should be noted that some of the more complex results
might be due to poor optimizer performance as the calibration method used is not perfect
(nor is any). Additional optimization trials might lead to significantly better results. The
sub-basins previously shown in figure 4.7 are all located in a geographic region with a
low local rain gauge density and no rain gauges actually lie within the sub-basin
boundaries. The best modeling results were produced by using a de-clustered data set. If
this study was done in reverse (i.e. starting with 8 rain gauges and increasing to 28), no
rain gauges are added within the sub-basin limits, and thus, there is no guarantee that
more data would improve modeling results.
The sub-basins previously shown in figure 4.6, which are located in a region with a
higher local rain gauge density, suffered from de-clustering. Again, if the study was
performed in reverse, several rain gauges would have been added within the limits of the
displayed sub-basins, and improved modeling results would have been expected.
The local rain gauge density in this study was found to be very important to
modeling results when the rain gauges were within the limits of the sub-basin being
modeled. When rain gauges are added outside the limits of a sub-basin, it is very difficult
to predict the effect it will have on modeling results.
This case study shows that portions of the model (sub-basins 26-29) with low local
rain gauge density can still produce reasonably accurate results (0.33 to 0.56 daily Nash-
Sutcliffe coefficients for this study as shown in table 4.6); however, sub-basins located
within geographic regions of higher rain gauge density (sub-basins 16-25) produced
significantly better and more consistent results (0.56 to 0.81 daily Nash-Sutcliffe
coefficients as shown in table 4.6). For a regional scale model it would be very difficult
to trust modeling results fuelled by a scarce data set regardless of the quality of the
model’s predictive power. With good values determined for the river class parameters,
the uncertainty in precipitation mainly translates to uncertainty in the land class
70
parameter values and can offset inaccurate precipitation input data produced by poor
local rain gauge density.
The results presented in this chapter are difficult to generalize to hydrologic models
in general, as the site was quite data poor with respect to available rain gauge data.
Without using an initial data set that contains consistently spaced rain gauges, the
importance of the rain gauge density for each trial can be very difficult to interpret. The
ideal scenario to test the effects of de-clustering would involve having a rain gauge
located in every grid cell in the study area. Gauges would then be removed according to
equation 4.1, and the model would be re-calibrated. Starting off the scenario with equally
spaced rain gauges would give more importance to the rain gauge density values when
compared to the resulting Nash-Sutcliffe coefficients of each de-clustered model.
A limitation that is always present in hydrologic modeling is the error in the
recorded historic precipitation data at each individual rain gauge, and this error can be
compounded when less data is available. While each rain gauge is likely to have some
error in each recorded precipitation event, the errors in models with a high density of data
points can even each other out when spatially interpolated. With a low density model
that essentially becomes subjected to a nearest neighbour interpolation, huge portions of
the model are fuelled by an input that is based on only one rain gauge that may have
significant error. The potential for this compounded error is another reason why models
with low rain gauge density are very difficult to trust.
The value of an added data point is only as good as the proximity it has to the sub-
basin being studied. In a regional scale model, with many sub-basins there are bound to
be geographic locations of the watershed that are relatively data-poor with regards to rain
gauge availability. To trust the results of a regional scale model that has parameter
flexibility similar to the WATFLOOD model used in this case study, the local rain gauge
density must be sufficient and at least partially within the boundaries of the sub-basins
considered. Though there is evidence that some data points can be removed without
significantly decreasing modeling accuracy in geographic locations with high rain gauge
71
density, the results of this chapter show that the best results for a regional scale model
will come from using all available precipitation inputs.
72
Chapter 5
Summary
This primary purpose of this thesis was to present a general approach to calibrating a
regional scale hydrologic model using a WATFLOOD model of the upper South
Saskatchewan River watershed as a case study. Initially, manual calibration was
described and performed on several sub-basins within the watershed. Using the manual
calibration results as a basis for automated calibration, a multi-basin automated
calibration approach was developed and applied to the model. The results demonstrated
that both methods were effective tools for improving modeling results. Not only were the
daily Nash-Sutcliffe coefficients of the sub-basins subjected to calibration all improved,
the results from x of y sub-basins used for validation were also improved. Additionally,
improvement in the monthly Nash-Sutcliffe coefficient was observed for every sub-basin
in the calibrated model relative to the pre-calibrated model. Overall, the average daily
Nash-Sutcliffe coefficient of the 19 calibration and validation sub-basins improved from
an initial value of 0.17 before calibration to 0.43 after manual calibration and then to 0.56
after refinements with automatic calibration.
The calibration method was applied to four models that used de-clustered
precipitation data as their input with the purpose of determining the effects of rain gauge
density on modeling results. The results of the four calibrations, based on the daily and
monthly Nash-Sutcliffe coefficients of all 19 sub-basins, were compared to the initial
calibrated model that used the entire precipitation data set. Of the 19 sub-basins
considered, 11 of had the best daily Nash-Sutcliffe coefficients in the model that used the
entire precipitation data set, and the best values for the remaining 8 sub-basins were
produced from a de-clustered model.
Calibration of the de-clustered models produced almost no variation in the river
class parameters from the values found during the calibration of the initial model.
Variation was found in the land class parameter values, but it was within a reasonable
73
range, with optimal parameters being modified less than one order of magnitude from
their original values. Because the variation in the river class parameters was so low
compared to the land class parameters, future de-clustering studies should consider
placing a priority on re-calibrating land class parameters and not river class parameters.
De-clustered models create uncertainty in precipitation volume which translates to
uncertainty in land class parameter values since they have a much higher influence on
runoff volumes than river class parameters.
In general, models that used more input data produced better modeling results than
de-clustered models; however, de-clustered models did produce better results in some
cases. Because the variation of the parameter values was within reasonable ranges for
each of these improved cases, extended study into the effects of precipitation gauge
density on modeling accuracy may provide stronger conclusions on how input
precipitation data can be modified or supplemented to improve modeling results.
