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.
This model archive makes available the calibrated Soil-Water-Balance (SWB) model used to simulate potential recharge for the Mississippi Alluvial Aquifer for 1915 to 2018. The model was calibrated using monthly values of evapotranspiration and annual values of runoff and recharge for 19 drainage basins selected from within or nearby the Mississippi Alluvial Aquifer system. The calibrated SWB model and its use are described in the associated U.S. Geological Survey Open-File Report 2021-1008. The model was used to create output at two different scales: 1,609-meter and 1,000-meter grid cells. Also included are files used to generate a high-resolution (100-meter) subset of output for an area near Shellmound, Mississippi....
This model archive makes available the calibrated Soil-Water-Balance (SWB) model used to simulate potential recharge for the State of Maine for 1991 to 2015. The model was calibrated using annual values of runoff, evapotranspiration, and recharge for 32 watersheds in the State. The simulations were used to create 25-year statistical grids of annual potential recharge (mean, median, minimum, and maximum), and the uncertainty around these grids. The calibrated SWB model and its use is described in the associated U.S. Geological Survey Scientific Investigations Report 2019-5125. The Maine SWB model was used to create output at two different scales: 250-meter and 500-meter grid cells. The calibration and uncertainty...
This item provides Soil-Water-Balance (SWB) model output and a model archive of water budget simulations for the Mississippi Embayment Regional Aquifer System (MERAS) during the period 2000 to 2020. Gridded daily data (1 kilometer resolution) include net infiltration (groundwater recharge), rejected net infiltration, runoff, irrigation, actual evapotranspiration and gross precipitation The model output files are in netcdf format and all water budget components are in inches. The net infiltration, rejected net infiltration, runoff, irrigation, and actual evapotranspiration data sets are from simulations done with the USGS SWB model (version 2; Westenbroek and others, 2018). The precipitation and temperature data...

This set of data includes four potential annual recharge grids for the State of Maine that were simulated using the Maine Soil-Water-Balance model for 1991 through 2015. The files include a grid representing the uncertainty in the potential recharge and a grid showing the annual average precipitation from the climate dataset that the simulation is based on. A 25-year simulation of potential recharge to groundwater from the Maine Soil-Water-Balance model for the years 1991 to 2015 produced annual results from which the four potential recharge grids were derived. The four are: 25-year mean, median, maximum, and minimum simulated annual potential. A data exclusion zone (see Scientific Investigations Report 2019-5125)...
