Groundwater Flow - DefinitionsGroundwater Flow - Definitions

Aquifer – Water saturated permeable Aquifer Water saturated permeable geologic unit that can transmit significant quantities of water (e.g., sands & gravels).q ( g , g ) Unconfined – water table forms the upper

boundary Confined – has overlying/underlying lower

permeabilty layers

f Water table – The top of the saturated zone. Hydraulic head – The water level in a well

expressed as an elevation.

Groundwater Flow – Definitions ( ti d)(continued)

Hydraulic conductivity (permeability) – A Hydraulic conductivity (permeability) – A physical property of the geologic media representing its ability to transmit water.

Specific yield – The volume of water that an unconfined aquifer releases from storage per unit surface area of aquifer per unit decline inunit surface area of aquifer per unit decline in water table elevation.

Storativity – The volume of water that a yconfined aquifer releases from storage per unit surface area of aquifer per unit decline in head.

Groundwater Flow – Definitions ( t’d)(cont’d)

Recharge The entry of water to the Recharge – The entry of water to the saturated zone at the water table:

Recharge = (precipitation + stream loss)Recharge = (precipitation + stream loss) minus (runoff + evapotranspiration).

Cross-formational flow – Groundwater flow Cross formational flow Groundwater flow between separate geologic formations.

Stream losses or gains – The water that is geither lost or gained through the base of the stream or river.

Basic Principles of GW FlowBasic Principles of GW Flow The primary observable quantity describing e p a y obse ab e qua t ty desc b g

groundwater flow is the water level as measured in a well.

The water level expressed as elevation is termed the hydraulic head.

The difference in hydraulic head between adjacent wells determines the direction of GW flow (from hi h h d t d l h d )higher heads towards lower heads).

The water table is typically a subdued replica of the topographythe topography.

Meeting Minutes for the First Rustler Groundwater Availability Model (GAM) Stakeholder

Advisory Forum (SAF) Meeting December 10th, 2009

Pecos County Courthouse, Ft. Stockton, Texas The first Stakeholder Advisory Forum (SAF) Meeting for the Rustler Groundwater Availability Model (GAM) was held on Thursday, December 10th, 2009 at 9:00 AM at the Pecos County Courthouse located at 103 West Callaghan in Ft Stockton, 79735. A list of meeting participants is provided at the end of these meeting notes. The primary purpose of the first SAF meeting is to provide an introduction to the Rustler GAM Team and the proposed approach to developing the model and to solicit input from stakeholders including any available data that could be made public. The meeting also provided a forum for discussing the project schedule and provided an opportunity for feedback from stakeholders.

Meeting Introduction: Wade Oliver, TWDB The meeting was initiated by Mr. Wade Oliver of the Texas Water Development Board (TWDB). He gave a brief introduction to the GAM Program and discussed how GAMs are used in Texas water resources planning. He then discussed GAMs and how they relate to Managed Available Groundwater as well as the importance of the stakeholder process.

SAF Presentation: Van Kelley, INTERA Inc Van Kelley (INTERA) presented a prepared presentation structured according to the following outline:

1. Introduction to the Rustler GAM Team 2. Rustler Regional Overview 3. Basics of Groundwater Flow 4. Overview of the Rustler Aquifer 5. Numerical Groundwater Modeling and the GAMs 6. Data Collection/Data Needs 7. GAM Schedule

The presentation is available on the GAM website:

http://www.twdb.state.tx.us/GAM/rslr/rslr.htm

Questions and Answers: Wade Oliver (TWDB) Presentation: Q: Does the TWDB publish any error bounds with their model predictions or are the

GAMs always used purely deterministically? A: Currently we do not calculate nor publish error bounds. This is a very difficult

process given the model complexity. Ideally one would consider model error and how this translates to monitoring and the compliance with Desired Future Conditions.

Q: I ask the question because I have to wonder when mean error from portions of the

Edwards-Trinity model is reduced from 256 ft to 80 ft. It seems there should be an error bound on the model predictions.

A: While your comment is true, complete and rigorous error analysis on these models is very involved and in the end the model error may be small in some cases relative to the assumptions in future resource use.

The following are a series of Stakeholder Comments in open discussion: C: With the Cenozoic-Pecos Alluvium aquifer GAM a sensitivity analysis was run

which gives one a good idea of the important parameters and which are unknown and those of those of us experienced in modeling already understand the uncertainties.

C: But the general public does not and they are the decision makers at the GMA. A: Formal one-off sensitivity analyses are performed for all GAMs.

Questions and Answers: Van Kelley (INTERA) Presentation: Q Will your study extend into the regions of the Rustler which have TDS

concentrations in excess of 5,000 ppm? A: Yes, the study will go out past 5000 ppm to establish natural boundaries for the

aquifer system. The TWDB defines the Rustler Aquifer to be that portion with TDS less than or equal to 5000 ppm.
