| Abstract | Direct download URL for the native MODFLOW-2000 model archive, found via TWDB's centralized GAM Files download page. 459MB zipped / 16.3GB unzipped -- the largest GAM archive found so far. Not yet independently verified via a Tapis test run. |
| Temporal Coverage Start | 2014-01-01 |
| Temporal Coverage End | 2014-12-31 |
| 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 GMA 6 member-county boundaries (TACC SUBSIDE texas_counties layer), not the precise model grid extent. |
