    Two finite-element ground-water flow models were developed for the Edwards–Trinity aquifer system, west-central Texas, to gain a better understanding of the flow system; one ground-water flow model was developed at a large scale to simulate the regional system and contiguous, hydraulically connected units, and one model was constructed at a smaller more detailed scale to simulate the most. Pecos Valley or Dockum aquifers at the downdip extent of the Edwards-Trinity aquifer. Additional details about the groundwater geochemistry and the conceptual groundwater flow in the model area are available in Bumgarner and others ().

Edwards and Trinity RegionalGroundwater Availability Model (GAM) Inthe Texas Water Development Board (TWDB) has begun to develop a regional groundwater availability model for the Edwards-Trinity (Plateau), Pecos Valley, Hill Country Trinity, and Edwards aquifers in Texas.

Bumgarner, Gregory P. Stanton. This report describes the study area, previous aquifer investigations, and hydrogeologic setting used to develop the Edwards Trinity and Pecos Valley aquifers conceptual models, and provides details on the study and suggestions for future model improvements.

The Edwards-Trinity (Plateau) and the Trinity Aquifers are designated as major aquifers in the state of Texas. Located in west-central Texas (), these two aquifers provide the primary source of water for the Edwards Plateau and the Hill Country regions of Edwards-Trinity (Plateau) Aquifer extends over an area of ~91, km 2 beneath all or parts of 41 counties.

Within the study area, Val Verde and Crockett counties are most vulnerable to drought because recharge is negligible when. Aquifer storage and recovery (ASR) uses an aquifer to store surplus water that will be available for later use when needed. The first textbook on ASR (Pyne,p.7) noted that ASR is “the storage of water in a suitable aquifer through a well during times when water is available, and recovery of the water from the same well during times when the water is needed.”.

A groundwater flow model was developed in for the Edwards-Trinity Aquifer within Val Verde County (Eco-Kai Environmental, Inc., and Hutchison, ). The objective of the model was to determine correlations and potential effects of groundwater pumping on local spring flows, lake elevations, and groundwater levels in Val Verde County.

The Edwards-Trinity aquifer is a vital groundwater resource for agricultural, industrial, and public supply uses in the Pecos County region of western Texas. The U.S. Geological Survey completed a comprehensive, integrated analysis of available hydrogeologic data to develop a numerical groundwater-flow model of the Edwards-Trinity and related.

Resource managers would like to understand the future availability of water in the Edwards-Trinity aquifer in the Pecos County region and the effects of the possible increase or temporal redistribution of groundwater withdrawals.

•Edwards-Trinity is the principal aquifer •Resource managers are concerned with future groundwater availability and the potential effects of withdrawal increases and/or redistribution •Scale of the existing regional Groundwater Availability Model (GAM) is too coarse to adequately simulate the Edwards-Trinity aquifer in the study area.The U.S.
