Groundwater modeling linked to SWAT aims to identify recharge options and long‑term pumping risks
Summary
A groundwater modeling team explained how SWAT-derived recharge will be linked to a refined groundwater (GMA8) model to assess pumping impacts, drawdown heat maps and potential sites for managed recharge; presenters invited local pumping data to refine results beyond the 2020 baseline.
The meeting included a detailed groundwater presentation by Rohit Goswami, who outlined approaches to refine a regional groundwater model by importing recharge from the SWAT hydrologic outputs and by updating pumping distributions.
Goswami described layered hydrogeologic formations used in the model and said the team refined the pumping and grid to improve local accuracy. He showed drawdown heat maps comparing 1980 and 2020 that indicate where pumping pressures are greater and where external pumping (from neighboring counties) may influence Coryell County water levels. "For Coryell itself, we have a lot of pumping going on in the Yamper formations in topmost layer," he said, explaining that some layers show minimal change while others show notable drawdown driven by outside pumping.
The team plans to run Desired Future Conditions (DFC) scenarios and climate‑extended SWAT runs to project outcomes to 2080. Presenters said they will accept local pumping records and requested that county and city stakeholders identify priority questions so the team can run targeted scenarios and report back within months.
