Central portion of the Gulf Coast Aquifer SystemGroundwater Availability Model (GAM)
The Texas Water Development Board (TWDB) contracted with Waterstone Environmental Hydrology and Engineering, Inc. (who was teamed with Intera, Inc., Parsons Engineering Science, Inc., and several individual experts) to develop a model of the central part of the Gulf Coast Aquifer in Texas.
TWDB staff has since recalibrated the central part of the Gulf Coast Aquifer while honoring historical pumpage (see below).
Work is underway to update the groundwater availability models for both the Central and Southern sections of the Gulf Coast Aquifer. Please see the page for the Gulf Coast Aquifer System Groundwater Availability Model, which will include both GMAs 15 and 16.
Figures from "Groundwater Availablity of the Central Gulf Coast Aquifer: Numerical Simulations to 2050, Central Gulf Coast, Texas."
Please see the GAM files download page for a copy of the model files.
Model grid cells are geographically assigned to counties, groundwater conservation districts, river basins, groundwater management areas, and regional water planning areas within the model study area using a centroid based approach. The model grid is available in ESRI® shapefile format and comma-delimited text file.
Aquifer data is only available as a package for the entire model area and requires GIS software for processing. Please see the GAM files download page for aquifer data.
