Updated Estimates of Water Budget Components for the Mississippi Embayment Region Using a Soil-Water-Balance Model, 2000–2024

This item provides Soil-Water-Balance (SWB) model input and output of a water budget simulation for the Mississippi Embayment Regional Aquifer System (MERAS) during the period 2000 to 2024. The output files include gridded daily data (1-kilometer resolution) for net infiltration (potential groundwater recharge), rejected net infiltration, interception, runoff, runoff outside (runoff that cannot be routed downslope), irrigation, actual evapotranspiration, minimum and maximum temperatures, and gross precipitation. The gridded daily representations of water budget components are output from USGS SWB model (Nielsen and Westenbroek, 2023; Westenbroek and Nielsen, 2023) simulations in netcdf4 format, and all water budget components are in inches.
The input files include the Cropland Data Layer land use rasters, climatological datasets produced by the PRISM group, and Landsat-based irrigated lands datasets.
Further details about this application of the SWB model can be found below in the 'Related External Resources' section. The primary publication can be accessed through links in the 'Related Primary Publication' subsection. These data provide updates to the previously published SWB version 2.0 estimates for 2000 to 2020 in https://doi.org/10.5066/P97KK17G, and the SWB version 1.0 estimates for 2000 to 2018 in https://doi.org/10.5066/P98PBR8O and https://doi.org/10.5066/P9U484X5.
