This data release contains datasets developed for the purpose of training and applying random forest models to the Mississippi Embayment Regional Study Area. The random forest models are designed to predict total stream flow and baseflow as a function of a combination of watershed characteristics and monthly weather data. These datasets are associated with a report (SIR 2022-5079) and code contained in a USGS GitLab repository. The GitLab repository (https://code.usgs.gov/map/maprandomforest/) contains much more information about how these data may be used to supply predictions of stream flow and baseflow.

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 USGS Soil-Water-Balance (SWB) Model was applied to 644 basins as defined at the level of an 8-digit hydrologic unit code (HUC). Support scripts, model inputs, and model outputs are provided in this archive.

This model archive makes available the calibrated Soil-Water-Balance (SWB) model used to simulate potential recharge for the glacial aquifer system east of the Rocky Mountains in the conterminous United States at a 1-kilometer (km) resolution for the period 1980-2011. The calibrated SWB model in this model archive and associated U.S. Geological Survey Scientific Investigations Report is referred to as the glacial SWB model. Potential groundwater recharge was determined on a daily basis as precipitation in excess of interception, runoff, evapotranspiration, and soil water storage capacity. Daily groundwater recharge amounts were aggregated to an annual basis for grids available in this model archive. Potential recharge...

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 data release includes four sets of gridded annual net infiltration (groundwater recharge) and irrigation water use data sets for the Mississippi Embayment Regional Aquifer System (MERAS).Also included are gridded water balance component data sets of precipitation, runoff, actual evapotranspiration, and soil-water storage for 2000 to 2018. The net infiltration, irrigation, runoff, actual evapotranspiration, and soil-water storage data sets are outputs from simulations done with the USGS Soil-Water-Balance (SWB) model (version 2; Westenbroek and others, 2018). The precipitation data was used as input for the SWB model application and is derived from DayMet version 3 (Thornton and others, 2018) and Livneh and...

Climate change is expected to alter the distributions and community composition of stream fishes in the Great Lakes region in the 21st century, in part as a result of altered hydrological systems (stream temperature, streamflow, and habitat). Resource managers need information and tools to understand where fish species and stream habitats are expected to change under future conditions. Fish sample collections and environmental variables from multiple sources across the United States Great Lakes Basin were integrated and used to develop empirical models to predict fish species occurrence under present-day climate conditions. Random Forests models were used to predict the probability of occurrence of 13 lotic fish...

In 2011-12, the U.S. Geological Survey conducted a study of the and hydrogeomorphic history and hydrodynamic characteristics of the lower 5 kilometers of the Sheboygan River, a tributary to Lake Michigan in eastern Wisconsin. The hydrogeomorphic history and stability of an ecologically important island complex in the Sheboygan River, the Wildwood Islands, was studied to determine the potential effects of inundation of island surfaces on riparian vegetation and potential areas of erosion and deposition. A two-dimensional (2D) channel hydraulics model was developed for simulating the interaction of riverine flows with varying lake levels and seiche effects. This dataset contains model input and output associated with...

This model archive provides input and output for Soil-Water-Balance (SWB) models developed for the Central Sands Lake study in central Wisconsin; this archive supplements the technical appendix in a report to the Wisconsin State Legislature written by the Wisconsin Department of Natural Resources (WDNR) in response to 2017 Wisconsin Act 10. This legislation directed DNR to determine whether existing and potential groundwater withdrawals are causing or are likely to cause significant reduction of mean seasonal water levels at Pleasant Lake, Long Lake, and Plainfield Lake (s. 281.34(7m)(2)(b), Wis. Stats.) in Waushara County, Wisconsin. The Soil-Water-Balance code (Westenbroek and others, 2018) partitions precipitation...

The U.S. Geological Survey, in cooperation with the Trinity River Authority, the Tarrant Regional Water District, the City of Dallas, and the North Texas Municipal Water District, constructed a finite-difference numerical groundwater-flow model of the Trinity River alluvium aquifer using MODFLOW with the Newton formulation solver (MODFLOW-NWT). This model, along with a surface water model and an analysis of long-term trends in water availability, was developed as a component of the Trinity River Basin Integrated Water Availability Assessment to evaluate future conditions under different global climate models. Thirty-three simulations are included in this data release, including one for the calibrated model, one...

This data release is a compilation of the digital products from a hydrogeologic framework of the glaciated conterminous United States that were constructed to portray sediment and aquifer characteristics within this area. These digital products are described in Yager, R.M., Kauffman, L.J., Soller, D.R., Haj, A.E., Heisig, P.M., Buchwald, C.A., Westenbroek, S.M., and Reddy, J.E., 2018, Characterization and occurrence of confined and unconfined aquifers in Quaternary sediments in the glaciated conterminous United States: U.S. Geological Survey Scientific Investigations Report 2018–5091, 90 p., https://doi.org/10.3133/sir20185091.
