| Abstract | TWDB GAM landing page for the Edwards-Trinity (Plateau) and Pecos Valley Aquifers (MODFLOW-2000). Direct model-archive download link not yet independently verified via a Tapis test run. |
| Temporal Coverage Start | 2011-01-01 |
| Temporal Coverage End | 2011-12-31 |
| Program Area | Groundwater |
| Data Contact Email | gam@twdb.texas.gov |
| Caveats and Usage | Regional GAM for planning and screening; not for site-specific design. Spatial extent is an approximate bounding box derived from the union of GMA 3, 4, 7, 9 member-county boundaries (TACC SUBSIDE texas_counties layer), not the precise model grid extent. |
