Soil-Water-Balance (SWB) model archive used to simulate potential annual recharge for the former Badger Army Ammunition Plant study area, Prairie du Sac, Wisconsin, 1980 to 2020.
Description
This model archive makes available the U.S. Geological Survey Soil-Water-Balance (SWB) model created in support of a groundwater flow model of the former Badger Army Ammunition Plant in Sauk County, Wisconsin. The SWB model provides initial estimates of potential recharge to the groundwater system in the study area, which are used in a calibrated 3-dimensional MODFLOW (modular finite-difference flow) model. The SWB and MODFLOW models run from 1980 to 2020. The model incorporates changing land use, and changes reflecting the decomissioning of the plant (changing urban back to non-urbanized). SWB output is broken up into 50 model timesteps for the MODFLOW model.
