This item provides a complete model archive for an application of the Soil-Water-Balance (SWB) model code to simulate water budget components of the Mississippi Embayment Regional Aquifer System (MERAS) during the period 2000 to 2020. All necessary data, model code, and model input files are provided so the simulations can be recreated. Gridded model outputs that were the basis for the primary publication are also provided. Gridded daily data (1 kilometer resolution) include net infiltration (water that might become groundwater recharge), rejected net infiltration, runoff, irrigation, actual evapotranspiration and gross precipitation Simulations were done with the USGS SWB model (version 2; Westenbroek and others, 2018). The precipitation and temperature data used as input for the SWB model application are derived from PRISM Climate products (PRISM Climate Group, 2020). Further details about this application of the SWB model can be found in the related primary publication

Gridded daily data (1 kilometer resolution) include net infiltration (water that might become 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 used as input for the SWB model application are derived from the PRISM group (http://prism.oregonstate.edu/; Daly and others, 1994). Further details about this application of the SWB model can be found in the related primary publication.The primary publication can be accessed through links in the related external resources section below. There are two child items: one with daily netcdf model output and one with a Soil-Water-Balance model archive. These data provide updates to previously published estimates for 2000 to 2018 in https://doi.org/10.5066/P98PBR8O and https://doi.org/10.5066/P9U484X5.

These netCDF output files from the Soil-Water-Balance Model contain daily calculations for the Mississippi Embayment Regional Aquifer System model domain of irrigation, net infiltration (recharge), runoff, soil moisture storage, and actual evapotranspiration amounts for the years 2000 to 2018 and gross precipitation as read from DayMet and processed through the USGS Soil-Water-Balance Model v.2.0 (Westenbroek and others, 2018). Input files used in the SWB run included agricultural land use as estimated by Brown and Pervez (2014) and provided by the USDA National Agricultural Statitical Service and soil properties derived from NRCS gSSURGO and STATSGO data (Wieczorek, 2014). Calculations were driven by DayMet version 3 daily precipitation and air temperatures (Thornton and others, 2018). Further details about the generation and application of the data can be found in Open File Report 2021-1008 (https://doi.org/10.3133/ofr20211008). These data are extracted from the model output contained in the companion model archive data release: https://doi.org/10.5066/P98PBR8O.

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. The directory structure of the model archive contains all of the files needed to document and run the model for a short example time period. This archive *does not* include all daily weather data drivers needed to replicate the model output; those files consume tens of gigabytes of storage space and are available elsewhere on the Internet (sources and online links to these data are provided in the source information section of the metadata). The directories in the archive are presented each as a separate .zip file and include a "bin" directory, a "georef" directory, a "model directory, an "output" directory, and a "source" directory. There is a README file describing all the files and directories in the archive and information on how to run the model. Each primary folder also contains a README file describing the contents.
