GAM Barton Springs Edwards Aquifer (updated 2026-01-13T16:52:11.954767Z)

This dataset contains numerical simulation input files and outputs from the MODFLOW-based groundwater availability model (GAM) for the Barton Springs segment of the Edwards Aquifer in Austin, Texas. It includes baseline, average, and user-customizable scenarios (M-B, M-A, and M-I) to assess the impact of drought conditions, water pumping, and recharge rates on groundwater resources. Key outputs include hydraulic head levels (hds), storage volumes (cbb), and pumping rates (cbb). The dataset was designed for use in groundwater management and planning by state agencies and stakeholders, focusing on sustainable water use under varying climatic and urban development conditions. The recharge zones and input configurations support analysis of drought impacts on water availability and ecosystem health.
