Barton Springs segment of the Edwards (Balcones Fault Zone) AquiferGroundwater Availability Model (GAM)
In 2008, the Texas Water Development Board (TWDB), in collaboration with the Barton Springs/Edwards Aquifer Conservation District, contracted with Southwest Research Institute® to develop a groundwater flow model for the Barton Springs segment of the Edwards Aquifer utilizing the MODFLOW-DCM code. The model was completed in 2009.
Please contact the GAM Section (512-936-0871) 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. Due to the size of raw/source data files for this model, this information has not been posted on the web. For the raw/source data, contact David Thorkildsen (512-936-0871).
