Input data, trained model data, and model outputs for predicting streamflow and base flow for the Mississippi Embayment Regional Study Area using a random forest model 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.

Most of the wells were measured annually or one time, after installation, but some wells were measured more than one time in a year and a small number of wells were measured continually. Streamgages were typically operated continuously.

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...

These estimates were developed with a regression for surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1301 gaged watersheds as a function of surficial geology type (USGS), precipitation (PRISM), slope (NHD), and soil hydraulic conductivity (STATSGO). The quantities for quick-flow runoff do not include inter-pixel transfers, so do not capture within-watershed variations due to such transfers such as downstream runoff accumulation, but rather represent the portion of the...

Well information is provided by the well drillers during the permitting process and is updated regularly by MoDNR. This data set consists of well records that were drilled into or through the Mississippi River Valley alluvial aquifer in an approximately 7 county area in southeastern Missouri as reported by the well drillers. Records that met specific threshold criteria were identified and statistical analysis done to ensure that the well was open to the Mississippi River Valley Alluvial...

Water availability can be limited in some areas of the aquifer by high concentrations of salinity, measured as specific conductance. Boosted regression trees (BRT), a type of ensemble-tree machine-learning method, were used to predict specific conductance concentration at multiple depths throughout the MRVA and underlying aquifers. Two models were created to test the incorporation of datasets from a regional aerial electromagnetic (AEM) survey and evaluate model performance. Explanatory variables...
