Summary

A MODFLOW-NWT groundwater/surface-water model was developed to evaluate the responses of low-flow conditions and groundwater levels within the lower San Antonio River Basin, Texas, USA under conditions of reduced recharge and increased groundwater withdrawals. There was concern that decreased recharge and increased groundwater withdrawals may adversely affect streamflow and groundwater levels. History-matching was carried out for the historical conditions of 2006-2013 using highly parameterized inversion with PEST++ which produced a maximum a posteriori model parameter set which formed the central tendency of a posterior parameter ensemble using FOSM- based Monte Carlo uncertainty analysis. The ensembles were also created for two scenarios [...]

Purpose

A MODFLOW-NWT model was developed for 2006-2013 historical conditions of the lower San Antonio River Basin, Texas, USA. The development of the model input and output files included in this data release are documented associated journal publication (https://doi.org/10.1111/gwat.13107). The model was developed, history-matched and model uncertainty was quantified to provide stakeholders with information to improve understanding of groundwater/surface-water interactions in the basin.
