Summary

The existing three-dimensional groundwater flow model (MODFLOW-2005) of the Mississippi Embayment Regional Aquifer system (MERAS), South-Central United States, was updated with: 1) higher stream density; 2) more spatially refined recharge; 3) better estimates of water use; 4) more recent time period simulated; 5) more realistic storage conceptualization; and 6) more robust handling of dry nodes through use of MODFLOW-NWT. For this study, the MODFLOW-NWT groundwater flow model was used to evaluate four parameter estimation algorithms with lower computational burdens. This work was performed to update the previous version of the MERAS groundwater flow model for decision making in the Mississippi Alluvial Plain (MAP), USA.This USGS data [...]

Purpose

The purpose of the groundwater flow model was to evaluate four parameter estimation algorithms with lower computational burdens for calibration of large environmental models, which formed the contribution of the Hunt et al. (2021) journal article. All approaches were applied to the same model developed for decision making in the Mississippi Alluvial Plain (MAP), USA. Explanation of the model included in this data release is documented in the associated Hunt et al. (2021) journal article and the associated Supporting Information appendix (https://doi.org/10.1111/gwat.13106).
