DOCUMENTATION OF THE HYDRUS PACKAGE FOR MODFLOW-2000,

THE U.S. GEOLOGICAL SURVEY MODULAR GROUND-WATER MODEL

By Hyeyoung Sophia Seo1, Jirka Šimůnek2, Eileen P. Poeter1

ABSTRACT

A new one-dimensional unsaturated flow package has been developed for and linked to the three-

dimensional modular finite-difference ground water model MODFLOW-2000. The HYDRUS Package uses the computer program HYDRUS to simulate water movement in variably-saturated porous media. HYDRUS is a finite-element code that solves the Richards equation. The flow equation incorporates a sink term to account for water uptake by plant roots. The boundary conditions for flow can vary with time. The HYDRUS Package begins with discretization of the soil profile into finite elements. Darcian flux is computed at each element of the soil profile. If necessary, the HYDRUS Package uses smaller time steps than MODFLOW with the time increment automatically adjusted to maintain accuracy. MODFLOW uses the time-averaged flux from the bottom of the unsaturated soil profile as recharge for the time step and calculates a new water depth, which is specified as a pressure head boundary at the bottom of the soil profile for the next time step. Zone arrays are used to define the cells to which the HYDRUS Package applies. This report documents the conceptual model, governing equations, and input instructions of the HYDRUS Package.

INTRODUCTION The HYDRUS Package for MODFLOW-2000 (Harbaugh et al, 2000) was developed to consider

the effects of infiltration, soil moisture storage, evaporation, plant water uptake, precipitation, and water accumulation at the ground surface.

The computational module from the HYDRUS-1D software package (Šimůnek et al., 2005) was adapted (e.g., solute and heat transport was removed, hysteresis in the soil hydraulic functions is not considered, only relevant boundary conditions remain) to simulate one-dimensional water movement in variably-saturated porous media. HYDRUS numerically solves the Richards equation and uses Galerkin-type linear finite element schemes. Integration in time is achieved using an implicit finite difference scheme for both saturated and unsaturated conditions. Solution efficiency has been improved for transient problems by automatically adjusting time step size. A sink term accounts for water uptake by plant roots, and the root water extraction rate is assumed to vary linearly over each mesh element. The HYDRUS Package discretizes the soil profile into finite elements, and defines the vertical distribution of hydraulic and other parameters characterizing the soil profile. The unsaturated soil hydraulic properties are described by user-selected van Genuchten (1980), van Genuchten with air entry value of -2 cm, or Brooks and Correy (1964) analytical functions.

MODFLOW zone arrays identify cells to which each unsaturated soil profile applies. The HYDRUS Package determines the flux from the variably saturated rigid porous medium and connects to MODFLOW as a head dependent flux boundary. Information about the average depth to water in each MODFLOW zone is delivered to the HYDRUS Package, which returns a flux calculated using its own time discretization for each MODFLOW time step. The flux is applied to every cell in the zone. The HYDRUS Package uses prescribed pressure head and flux boundaries, and boundaries controlled by atmospheric conditions such as precipitation, evaporation, and transpiration.

The user defines precipitation, potential evaporation, and potential transpiration rates for the profile. The net infiltration rate, i.e., the difference between precipitation and evaporation is estimated during the simulation. Therefore, there is no need to use MODFLOW-2000 Evapotranspiration (EVT) and recharge (RCH) Packages simultaneously in the same vertical column with the HYDRUS Package. The RCH Package can be used to simulate recharge from sources other than surface processes if desired. The EVT Package cannot be used with the HYDRUS Package.

Purpose and Scope

The purpose of this report is to present a new unsaturated flow package, which is compiled with the three-dimensional modular finite-difference ground water model MODFLOW-2000. The HYDRUS Package simulates one-dimensional water flow. This simplicity is an advantage for large simulations due to its computational efficiency relative to a three-dimensional unsaturated flow simulation. Computational time can be reduced by applying each profile to a zone of cells rather than individual cells. The same zonation and soil profiles need to be used for the entire simulation. When a zone of cells is used for a profile, the average depth to water for all cells in the zone is used as the lower boundary condition for the soil profile. Consequently the user may want to use the same profile for many different zones.

The source code was developed and tested using the Compaq Visual Fortran and Lahey/Fujitsu Fortran 95 compilers.

CONCEPTUALIZATION AND IMPLEMENTATION OF THE HYDRUS PACKAGE

The HYDRUS Package analyzes one-dimensional water flow in variably saturated porous media

based on precipitation, potential evaporation rate, potential transpiration rate, plant water uptake, and water accumulation at the ground surface. The process begins with the discretization of the soil profile into finite elements, and definition of the vertical distribution of hydraulic and other parameters characterizing the soil profile (Figure 1-A). The soil profile needs to represent materials from the surface to the deepest level expected for the water table at any time during the simulation.

Each HYDRUS profile is applied for one or more MODFLOW zones that can include one or more cells. The average depth to ground water (ground surface - water table elevation) of all MODFLOW cells in the zone is used to determine the bottom boundary pressure head value in the HYDRUS profile: HB = ZSURF – DEPTH – Z1 (1) where HB is the pressure head at the bottom of the soil profile (i.e. the height of the water column above the bottom of the soil profile); ZSURF is the elevation of the ground surface; DEPTH is the depth to ground water; and Z1 is the coordinate of the bottom of the soil profile (Figure 1-A).

The user is allowed to make as many unsaturated profiles as he/she likes, i.e., one unsaturated profile for every cell or a group of cells (Figure 1-B). When a group of cells is specified, the depth to ground water in each cell of the zone is averaged to determine the hydraulic head at the bottom of the soil profile. The time-averaged flux from the bottom of the soil profile is applied to each cell in the zone as recharge for the time step.

The unsaturated zone finite element mesh is constructed by dividing the soil profile into one-dimensional linear elements connected at nodal points. The thickness of each finite element is controlled by the node locations and cannot be changed during the simulation. It is recommended that the size-ratio of two neighboring elements not exceed about 1.5. The nodes are numbered sequentially from 1 to NumNP (total number of nodes) from the bottom of the soil profile to the soil surface. The element dimensions should be relatively small at locations where large hydraulic gradients are expected. Such a region is usually located close to the soil surface where highly variable meteorological factors can cause rapid changes in the soil water content and corresponding pressure heads. Therefore, relatively small elements are recommended near the soil surface, with gradually larger sizes deeper in the soil profile. Soil hydraulic properties also need to be considered when defining element dimensions. Coarse textured soils generally require a finer discretization than fine-textured soils (loams, clays). No special grid configuration is required to simulate the soil root zone.

The flow region itself may be composed of nonuniform soils. Soil properties beginning with 1 and ending with NMat (the total number of soil materials) must be assigned to all nodal points of the finite element mesh (Figure 2-A). When different material numbers are assigned to a node, material properties of the adjacent elements are interpolated linearly between nodes by the finite element algorithm. This procedure blurs soil interfaces. Note that the bottom of the soil profile needs to be below the water table throughout the simulation. The flux is calculated at the bottom of the soil profile, which must always be saturated (pressure at this boundary is equal to the height of saturated column above that elevation). The flux is applied to the MODFLOW layer which the user specifies as either the highest active cell or layer one. If layer one is selected and layer 1 goes dry, then the simulated infiltration is not input to the simulation.

The HYDRUS Package solves the Richards equation and determines the flux at the bottom of the soil profile using time sub-steps for each MODFLOW time step. MODFLOW receives the flux as recharge and calculates a new water depth for the time step, which is assigned as the new pressure head at the bottom of the soil profile in the HYDRUS Package for the next MODFLOW time step. The procedure is presented in Figure 3. The governing equations, numerical solution strategy, and input instructions of the HYDRUS Package are presented in the following section.

Governing Flow Equation

The one-dimensional unsaturated flow package is used to describe the effects of infiltration, soil moisture storage, evaporation, plant water uptake, precipitation, and water accumulation at the ground surface. Water movement in the unsaturated zone is assumed to occur only in the vertical direction, which is described by a modified form of the Richards equation, which is expressed as:

hK K St z zθ∂ ∂ ∂⎛ ⎞= + −⎜ ⎟∂ ∂ ∂⎝ ⎠

, (2)

where

θ is the volumetric soil water content which is a function of the pressure head for a given material [dimensionless];

t is time [T]; z is the spatial coordinate [L] (positive upward); K is the unsaturated hydraulic conductivity at the current pressure head [LT-1]; h is the water pressure head [L]; and S is the sink term [T-1].

The Richards equation is based on the assumptions that the air phase plays an insignificant role in the liquid flow process, and that water flow due to thermal gradients can be neglected (e.g., Šimůnek et al, 1998). This solution requires the initial distribution of the pressure head within the flow domain.

Unsaturated Soil Hydraulic Properties

The unsaturated soil hydraulic properties, θ and K, in equation (2) are, in general, highly nonlinear functions of the pressure head, h. The unsaturated hydraulic conductivity function, K, is expressed as:

),()(),( zhKzKzhK rs= , (3) where Kr is the relative hydraulic conductivity [-], Ks is the saturated hydraulic conductivity [LT-1], and z is the spatial coordinate [L]. The user may choose from three types of analytical models for the hydraulic properties: Brooks and Corey's (1964) model, van Genuchten's (1980) model, and van Genuchten's model with the air entry value of -2 cm. At the beginning of a simulation, tables of water contents, hydraulic conductivities, and specific water capacities are produced for each soil type from the specified input of hydraulic parameters. The values of θi, Ki and Ci in each element are evaluated at prescribed pressure heads hi within a specified interval. The values are generated such that:

=+

i

i

hh 1 constant, (4)

which means that the spacing between two consecutive pressure head values increases in a logarithmic fashion. Values for the hydraulic properties, θ (h), K(h) and C(h), are computed during the iterative solution process using linear interpolation. If an argument h falls outside the prescribed interval, the hydraulic characteristics are evaluated directly from the hydraulic functions, i.e., without interpolation. Computation by the interpolation technique is much faster than direct evaluation of the hydraulic functions over the entire range of pressure heads, except when very simple hydraulic models are used.

van Genuchten model van Genuchten (1980) used the statistical pore-size distribution model of Mualem (1976) to obtain a predictive equation for the unsaturated hydraulic conductivity function in terms of soil water retention parameters. The soil water retention, θ (h), and hydraulic conductivity, K(h), functions are given by:

where 1 1 1m = - /n , n > . (10) The above equations contain six independent parameters: θr, θs, α, n, l, and Ks. The pore-connectivity parameter l in the hydraulic conductivity function is estimated to be about 0.5 as an average for many soils (Mualem, 1976).

The Mualem (1976) pore-size distribution model for predicting soil hydraulic conductivities often predicts for fine textured soils unrealistically fast decrease of the hydraulic conductivity close to saturation. Much better predictions of soil hydraulic conductivities for fine textured soils can be obtained if the van Genuchten (1980) model is modified by assuming an air-entry value of -2 cm (Vogel et al.,

9

2001). This modification leads to an almost imperceptible change in the description of the retention curve (especially for fine textured soils; one cannot practically see any differences when plotting the two functions), but much more pronounce change in the unsaturated hydraulic conductivity function. The function decreases significantly slower with decreasing water content (pressure) than the original function (see Vogel et al., 2001). The modified van Genuchten model does not require any additional input parameters and it leads to much more numerically stable solutions, since it significantly reduces the nonlinearity of the soil hydraulic functions.

Space and Time Discretization

The soil profile is first discretized into N − 1 adjoining elements, with the ends of the elements located at the nodal points, and N being the number of nodes. The HYDRUS Package assumes that the vertical coordinate z is directed positive upward.

A mass-lumped linear finite element scheme is used for discretization of the mixed form of the Richards equation (2). Since the mass-lumped scheme results in an equivalent and somewhat standard finite difference scheme, the detailed finite element development is omitted and the invoked final finite difference scheme is given:

Equation (11) is based on a fully implicit discretization of the time derivative, and is solved with a Picard iterative solution scheme. Notice also that the sink term, S, is evaluated at the previous time level. The mass-conservative method proposed by Celia et al. (1990), in which θ j+1, k+1 is expanded in a truncated Taylor series with respect to h about the expansion point h j+1, k, is used in the time difference scheme of Equation (11):

This method has been shown to provide excellent results in terms of minimizing the mass balance error. The second term on the right hand size of equation (13) is known prior to the current iteration. The first term on the right hand side of equation (13) should vanish at the end of the iteration process if the numerical solution converges.

The tridiagonal matrix [Pw] is symmetric, and therefore the below-diagonal entries are equal to the above-diagonal entries. The entries d1, e1, f1, and eN-1, dN, fN are dependent upon the prescribed boundary conditions.

Initial and Boundary Conditions

The solution of Equation (2) requires knowledge of the initial distribution of the pressure head within the flow domain:

11

)(),( zhtzh i= when t = t0, (20) where hi [L] is a prescribed function of z, and t0 is the time when the simulation begins.

Boundary conditions for fluid simulation are expressed either as a first-type (Dirichlet) or a second-type (Neumann) boundary condition. The Dirichlet boundary condition applies where the value of a component is fixed at a particular boundary, and the Neumann boundary condition applies where the cross-boundary flux of a component is fixed at a particular boundary.

A Dirichlet boundary with a prescribed pressure head, h0, is specified at the bottom of soil profile (i.e., z = 0): )(),( 0 zhtzh = at z = 0 (21)

At the soil surface (i.e., z = L), the soil-air interface is exposed to atmospheric conditions and the potential fluid flux across this interface is controlled exclusively by external conditions. However, the actual flux depends also on the prevailing (transient) soil moisture conditions near the surface. The numerical solution of equation (2) is obtained by limiting the absolute value of the surface flux by the following two conditions (Neuman et al., 1974):

LzEKzhK =≤−∂∂

− at , (22)

and Lzhhh SA =≤≤ at , (23) where E is the maximum potential rate of infiltration or evaporation under the current atmospheric conditions [LT-1], and hA and hS are, respectively, minimum and maximum pressure heads at the soil surface allowed under the prevailing soil conditions [L]. The value of hA is determined from the equilibrium conditions between soil water and atmospheric water vapor, whereas hS is usually set equal to zero. When the pressure head, h, exceeds the maximum allowed pressure head, hS, surface runoff is initiated. The HYDRUS Package calculates the amount of infiltration at the maximum allowed pressure head, hS, and the rest is removed by surface runoff. A positive value of hS represents a small layer of ponded water that can form on top of the soil surface during heavy rain before runoff begins.

Any excess water on the soil surface can be immediately removed by using an option in the HYDRUS Package. When one of the end points of equations 22 or 23 is reached, a prescribed head boundary condition will be used to calculate the actual surface flux. Methods of calculating E and hA on the basis of atmospheric data have been discussed by Feddes et al. (1974). On the other hand, the user can permit water to build up on the surface. When surface accumulation is expected to develop, the following equation may be selected by the user (Mls, 1982):

0 ( ) ath dhK K q t z Lz dt∂

− − = − =∂

. (24)

The flux q0 in this equation is the net infiltration rate, i.e., the difference between precipitation and evaporation. Equation (24) reveals that the height h (L, t) of the surface water layer increases due to precipitation, and decreases in response to infiltration and evaporation.

12

Atmospheric boundaries are simulated by applying either prescribed head or prescribed flux boundary conditions depending upon whether equation (22) or (23) is satisfied (Neuman, 1974). If equation (23) is not satisfied, then boundary node n becomes a prescribed pressure head boundary. If, at any point in time during the computations, the calculated flux exceeds the specified potential flux in equation (22), the node is assigned a flux equal to the potential value and is treated as a prescribed flux boundary.

Atmospheric boundary conditions are implemented at the soil surface, in which case time-dependent input data for the precipitation, Prec, and evaporation, rSoil, rates must be specified in the input file. The potential fluid flux across the soil surface is determined by rAtm=rSoil-Prec. Two limiting values of surface pressure head must also be provided: hCritS which specifies the maximum allowed pressure head at the soil surface (usually 0.0), and hCritA which specifies the minimum allowed surface pressure head (defined from equilibrium conditions between soil water and atmospheric vapor). When hCritS is exceeded, water starts accumulating, which initiates surface runoff. Then, the boundary condition is switched from a flux to a head boundary (with head = hCritS) and that controls the infiltration rate. Excess water is assumed to be removed by surface runoff. Similarly, when hCritA is exceeded (very dry soil), the code switches from a flux (potential evaporation) to a head boundary condition and calculates evaporation rate (actual evaporation). This leads to reduction of potential evaporation to actual evaporation.

When a flux boundary condition is used at the top of the soil profile, the mass balance equation is used in numerical implementation rather than Darcy's law because it is more stable and mass-conservative:

where qN is the prescribed soil surface boundary flux. Implementation of a Neumann boundary condition always preserves symmetry of the matrix [Pw].

When a Dirichlet condition is specified at the bottom of the soil profile, d1 is unity, e1 reduces to zero in the matrix [Pw], and f1 equals the prescribed pressure head, h0 in the equation (21). Additional rearrangement of the matrix [Pw] is necessary to preserve its symmetry. The appropriate entries in the second equation containing the prescribed boundary pressure head h0 in the left-hand side matrix are incorporated into the known vector on the right-hand side of the global matrix equation. This rearrangement restores the symmetry of the matrix [Pw].

Iterative Process

The nonlinear nature of equation (15) requires an iterative process be used to obtain a solution to the global matrix equation at each new time step. A system of linearized algebraic equations is first derived from equation (15), and the equation is solved using Gaussian elimination after incorporation of the boundary conditions for each iteration. The Gaussian elimination process takes advantage of the tridiagonal and symmetric features of the coefficient matrix in equation (15). After solving equation (15) the first time, the coefficients in equation (15) are re-evaluated using this first solution, and equation (15) is solved again. The iterative process continues until a satisfactory degree of convergence is obtained, i.e., until the absolute change in pressure head (or water content) between two successive iterations becomes less than some small value determined by the imposed absolute pressure head (or water content) tolerance at all nodes. The first estimate (at zero iteration) of the unknown pressure heads at each time step is obtained by extrapolation from the pressure head values at the previous two time levels.

Time Control There are three different time discretizations in the HYDRUS Package: (1) time discretizations associated with the numerical solution, (2) time discretizations associated with the implementation of boundary conditions, and (3) time discretizations which provide printed output of the simulation results (e.g., nodal values of dependent variables, water, and other information about the flow regime).

Discretizations (2) and (3) are mutually independent; they generally involve variable time steps as described in the input data file. Discretization 1 starts with a prescribed initial time increment, Δt. This time increment is automatically adjusted at each time level according to the following rules (Mls, 1982; Šimůnek et al., 1992):

a. Discretization 1 must coincide with time values resulting from time discretizations 2 and 3. b. Time increments cannot become less than a preselected minimum time step, Δtmin, nor exceed a

maximum time step, Δtmax (i.e., Δtmin ≤ Δt ≤ Δtmax). c. If, during a particular time step, the number of iterations necessary to reach convergence is ≤ 3, the

time increment for the next time step is increased by multiplying Δt by a predetermined constant >1 (usually between 1.1 and 1.5). If the number of iterations is ≥ 7, Δt for the next time level is

14

multiplied by a constant < 1 (usually between 0.3 and 0.9). d. If, during a particular time step, the number of iterations at any time level becomes greater than a

prescribed maximum (usually between 10 and 50), the iterative process for that time level is terminated. The time step is subsequently reset to Δt/3, and the iterative process restarted.

Root Water Uptake Water uptake by roots has a great effect on the flow within the root zone. Since precise data are

rarely available, root water uptake is often represented as an extraction or sink term, S(h), distributed over the root zone. Feddes et al. (1978) described the sink term as:

pShhS )()( α= , (33) suggesting that the root extraction, S, depends on the soil moisture pressure head, h, and the potential water uptake rate, Sp [T-1]. S decreases during times of water shortage by the factor α(h), which is a user prescribed dimensionless function of the soil water pressure head (0 ≤ α ≤ 1) illustrated in Figure 4. Root water uptake, S, is assumed to be zero close to saturation (i.e., wetter than some arbitrary “anaerobiosis point” (h1) and under conditions drier than the “wilting point” (h4). It is considered to be maximal when the soil water pressure heads are between h2 and h3, whereas for pressure heads between h3 and h4 (or h1 and h2), water uptake decreases (or increases) linearly with h to zero. Figure 4. General shape of dimensionless sink term variable, α(h), as a function of the soil water pressure head, h (after Feddes et al., 1978) (Tp is the potential transpiration rate).

The value of h3 depends on the water demand of the atmosphere; therefore, it varies with Tp. Kroes and Van Dam (2003) provided high and low estimates of h3 for a large number of crops. The value of h3 in Figure 4 is estimated based on the following interpolation.

Tp – is the potential transpiration rate [LT-1]. The same linear interpolation scheme is used in several versions of the SWATRE code (e.g., Wesseling and Brandyk (1985), in SWMS_2D (Šimůnek et al., 1992) and HYDRUS-2D (Šimůnek et al., 1999) codes.

When the potential water uptake rate, Sp, is distributed equally over the rooting depth, it becomes:

TS = , (37)

where Tp is the potential transpiration rate [LT-1] and LR the thickness [L] of the root zone. Equation (33) may be generalized by introducing a non-uniform distribution of the potential water uptake rate over a root zone of arbitrary shape:

pp TzbzS )()( = , (38)

where b(z) is the normalized water uptake distribution [L-1]:

This function describes the spatial variation of the potential extraction term, Sp, over the root zone (Figure 5), and is obtained by normalizing a measured or prescribed root water uptake distribution function, b′(z), which is usually proportional to the root density distribution. Normalizing the uptake distribution ensures that b(z) integrates to unity over the root zone.

When the potential root water uptake distribution, b, is greater than zero, the root water extraction rate is assumed to vary linearly over each element, and the HYDRUS Package calculates the total rate of transpiration using the equation:

HYDRUS PACKAGE INPUT

Input to the HYDRUS Package is read from the file that is type “HYDRUS” in the name file. All single-valued variables are free format if the option “FREE” is specified in the Basic Package input file; otherwise, the variables have fields that are 10 columns wide. An integer is required for parameters that have a name starting with any of the letters I through N. Otherwise a real number is expected.

Explanation of Variables in the Name File

Text – is a character variable (199 characters) that starts in column 2. Any characters can be included in Text. The “#” character must be in column 1. Except for the name file, lines beginning with “#” are restricted to these first lines of the file. Text is printed when the file is read. NPUNSP – is the number of unsaturated flow profiles. NHYDRUSOP – is the unsaturated flux option code. The flux is either applied to the first layer in each vertical column or to the highest active layer. 1 – the unsaturated flux is applied to layer one (the flux is ignored if layer one is dry). 2 – the unsaturated flux is applied to the highest active layer in each vertical column. IHYDRUSCB – is a flag and a unit number. If IHYDRUSCB > 0, it is the unit number to which cell-by-cell flow terms will be written when “SAVE BUDGET” or a non-zero value for IHYDRUSCB is specified in Output Control.

20

If IHYDRUSCB ≤ 0, cell-by-cell flow terms will not be written. IHYDRUSpr – is an output flag. The possible values of IHYDRUSpr and their meanings are as follows:

If IHYDRUSpr = 0, then only input is printed. If IHYDRUSpr = 1, then an echo of input and the fluxes from the HYDRUS package are printed at the end of each time period. If IHYDRUSpr = 2, then no input is echoed but fluxes are printed at the end of each time step.

NMAT – is the total number of soil materials in the model domain. Materials are identified by the material number, MAT. MAXNP – is the maximum number of nodal points with HYDRUS boundaries. MAXATM – is the maximum number of atmospheric data. Zonarr – is the name of the zone array to be used to define the cells that are associated with each profile. The name “ALL” means that there is no zone array and one HYDRUS profile is used for all MODFLOW grid cells. The name “EACH” means that the HYDRUS profile is used for each MODFLOW grid cell. MaxIt – is the maximum number of iterations allowed during any unsaturated flow calculation time step, while solving the nonlinear Richards' equation using a modified Picard method. The suggested value is 10. TolTh – is the absolute water content tolerance for nodes in the unsaturated flow model (the suggested initial value is 0.001). TolTh represents the maximum desired absolute change in the value of the water content between two successive iterations during a time step. If the numerical solution does not converge, the user may try to relax these criteria, or use finer discretization. TolH – is the absolute pressure head tolerance for nodes in the saturated flow model (its recommended initial value is 1 cm). TolH represents the maximum desired absolute change in the value of the pressure head between two successive iterations during a particular time step. If the numerical solution does not converge, the user may try to relax these criteria, or use finer discretization. DT – is the initial time increment, Δt [T]. Initial time step should be estimated with respect to the problem being solved. For problems with high pressure gradients (e.g. infiltration into and initially dry soil), Δt should be relatively small. The suggested value is 0.01 d. DTMIN – is the minimum permitted time increment for the unsaturated zone model, Δtmin [T]. The suggested value is 1 s. DTMAX – is the maximum permitted time increment for the unsaturated zone model, Δtmax [T]. DMUL – is the dimensionless number to multiply Δt for the next time step when the number of required iterations at a particular time step is less than or equal to ITMIN. The recommended value ranges between 1.0 and 1.3. DMUL2 – is the dimensionless number to multiply Δt for the next time step when the number of required iterations at a particular time step is less than or equal to ITMAX. Usually DMUL2 is less than 1.0, and the recommended value is 0.7.

21

ITMIN – is the lower optimal iteration range. When the number of iterations necessary to reach convergence for water flow is less than or equal to this number, the time step is multiplied by a dimensionless number DMUL. Recommended value is 3. ITMAX – is the upper optimal iteration range. When the number of iterations necessary to reach convergence for water flow is higher than this number, the time step is multiplied by a dimensionless number DMUL2. Recommended value is 7. HTAB1 – is the absolute value of the upper limit [L] of the pressure head interval below which a table of hydraulic properties will be generated internally for each material (HTAB1 must be greater than 0.0; e.g. 0.001cm). HTABN – is the absolute value of the lower limit [L] of the pressure head interval for which a table of hydraulic properties will be generated internally for each material (e.g. 1000m). If the absolute value of the pressure head during program execution lies outside of the interval [HATB1, HTABN], then appropriate values for the hydraulic properties are computed directly from the hydraulic functions (i.e. without interpolation in the table). IMODEL – indicates the soil hydraulic properties model:

= 0; van Genuchten = 1; van Genuchten with air entry value of -2 cm = 2; Brooks and Corey

THR – is the residual water content. THS – is the saturated water content. ALPHA, N, and L are empirical coefficients affecting the shape of the hydraulic functions.

ALPHA – is the inverse of the air-entry value (or bubbling pressure) in the Brooks and Corey (1964) function and an empirical shape parameter in the van Genuchten (1980) function

N – is the pore size distribution index L – is the pore-connectivity (or tortuosity) parameter KS – is the saturated hydraulic conductivity. IZ – is the zone number that defines the cells associated with the profile. These values are omitted if Zonarr is specified as “ALL” or “EACH”. When Zonarr is specified as “EACH”, the HYDRUS Profile starts reading from a cell at column 1 and row 1 and moves to column 2 and row 1. SINKF – is the root water uptake flag. If SINKF ≥ 0, water extraction from the root zone occurs. If SINKF < 0, no water extraction from the root zone. WLAYER – is the water accumulation flag. If WLAYER ≥ 0, water can accumulate at the surface (There is no surface runoff until HCRITS is

reached). If WLAYER < 0, any excess water on the soil surface will be immediately removed (It is

assumed to runoff). LINITW – is the initial condition flag.

22

If LINITW ≥ 0, the initial condition is given in terms of the water content. If LINITW < 0, the initial condition is given in terms of the pressure head. NOMAT – is the number of soil materials in the profile. NUMNP – is the number of nodal points. N – is the nodal number. Nodes are numbered sequentially from 1 to NumNP (total number of nodes) from the soil surface to the bottom of the soil profile. Z(n) – is the Z-coordinate of node n. H – is the initial value of the pressure head (expressed in terms of a height of a column of water) or the water content depending on LINITW. MAT – is the index for material whose hydraulic properties are assigned to node n. BETA – is the value of water uptake distribution, b(z) [L-1], in the soil root zone at the node n. Set beta (n) equal to zero if node n lies outside the root zone. b(z) is the normalized water uptake distribution in the equation (39). H1 – is the value of the pressure head below which the roots start to extract water from the soil (see Fig. 4). H3HIGH – is the value of the limiting pressure head at which the roots cannot extract water at the maximum rate (assuming a potential transpiration rate of r2H). H3LOW – is the value of the limiting pressure head at which the roots cannot extract water at the maximum rate (assuming a potential transpiration rate of r2L). P4 – is the value of the pressure head below which root water uptake ceases (usually equal to the wilting point). rHIGH – is the highest potential transpiration rate [LT-1]. rLOW – is the lowest potential transpiration rate [LT-1]. POPTM – is the value of the pressure head below which roots start to extract water at the maximum possible rate. MAXAL – is the number of atmospheric data records. hCritS – is the maximum allowed pressure head at the soil surface (usually 0.0). tAtm – is the time for which the i-th atmospheric data record is provided [T]. Time is specified relative to the start of the MODFLOW simulation. Prec – is the precipitation rate [LT-1]. Prec, rSoil, and rRoot are always positive. If a negative value is entered, the absolute value will be used. rSoil – is the potential evaporation rate in absolute value [LT-1].

23

rRoot – is the potential transpiration rate in absolute value [L/T]. hCritA – is the absolute value of the minimum allowed pressure head at the soil surface [L] (defined from equilibrium conditions between soil water and atmospheric vapor).

EXAMPLE The example problem (Figure 6) consists of three layers: an unconfined aquifer, an aquitard, and a convertible initially confined aquifer. The groundwater below level field generally flows from the hillside to the riverside. The primary source of groundwater is recharge from precipitation. The hillside is considered impermeable and thus a no-flow boundary. A river boundary is present to the south. Surface runoff is assumed to be negligible. Half of the level field to the south is covered with grass, and the soil surface boundary condition involves precipitation and potential transpiration rates for the grass cover. For the other half of the field, all precipitation is assumed to infiltrate. The unconfined aquifer is composed of sand, silt, and clay (Figure 6). We expect the water table will not fall below the bottom of layer one so the soil columns are defined only for materials in layer one. Two soil columns are defined using the HYDRUS Package. Figure 6.
