This dataset includes 800m resolution long-term average estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 2000-2013 and annual estimates for the individual years. These estimates were developed with a new empirical regression for surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1434 gaged watersheds as a function of surficial geology type (USGS), precipitation (PRISM), and soil hydraulic conductivity (STATSGO). Irrigated water quantities reported in the 2000, 2005, and 2010 USGS Water Use datasets are also incorporated as effective additional precipitation. The contributing input datasets...

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 dataset includes 1km resolution monthly timescale estimates of evapotranspiration (ET) for the 2000-2015 timespan. These new SSEBop-WB estimates were developed by combining a previously published long-term annual average evapotranspiration map based on water balance constraints with the SSEBop remote sensing ET product (see Associated Items). The combination aims to leverage the advantages of each approach in gaining both the temporal resolution of remote sensing data and the long-term magnitude constraints of ground-based data. This data release also includes other supporting data associated with the publication of these estimation methods in a concurrent journal article. Analyses in the journal article included...

A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. 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 potentiometric surface map for 2016 was created as part of the U.S. Geological Survey (USGS) Water Availability and Use Science Program to support investigations that characterize...

These netCDF output files from the Soil-Water-Balance Model contain daily calculations for the Mississippi Embayment Regional Aquifer System model domain of irrigation and net infiltration (recharge) amounts for the years 1915 to 1999. Input files used in the SWB run included historical agricultural land use as estimated by Sohl and others (2015), soil properties derived from NRCS gSSURGO and STATSGO data (Wieczorek, 2014), and 20th century gridded precipitation and air temperature as estimated by Livneh and others (2013). Spatial extent of the output files is the approximate boundary of the Mississippi Embayment Regional Aquifer System. Further details about the generation and application of the data can be found...

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...

This dataset includes 1 km resolution monthly timescale estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 1895-2017. 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...

As demands on groundwater continue to increase, decision-makers need all available information to ensure the sustainability of this important natural resource. Since the 1940's, commercial, academic, and government hydrologists have used aquifer tests to estimate the hydrogeologic properties of an aquifer near test wells. Results from these tests are recorded in various files, databases, reports, and scientific publications. The Lower Mississippi-Gulf (LMG)-Hydrogeologic Aquifer Test dataset aggregates aquifer test results from Alabama, Arkansas, Louisiana, Mississippi and Tennessee into a single dataset that is publicly available in a machine readable format. The dataset includes the following information: Location...

The Missouri Department of Natural Resources’ (MoDNR) Well Information Management System (WIMS) is a repository for recent (1983–present) well information that includes date of completion, well construction, geology, and water level. 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...

These estimates were developed with new empirical regressions for (1) surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1509 gaged watersheds as a function of surficial geology type (USGS), precipitation (PRISM), and soil hydraulic conductivity (STATSGO); and (2) long-term evapotranspiration from water balance estimates at 679 gages as a function of land cover (NLCD), precipitation (PRISM), and maximum, minimum, and mean daily temperature (PRISM). The recharge quantites close the water...

These estimates were developed with a new empirical regression for long-term water balance ET data at 679 gaged watersheds as a function of land cover (NLCD), precipitation (PRISM), and maximum, minimum, and mean daily temperature (PRISM). A separate map is also included of evapotranspiration estimated over open-water areas from the empirical Meyer 1944 mass transfer equation, as a function of wind speed (gridMET data set, www.climateengine.org), temperature (PRISM), and dewpoint temperature data (PRISM).

Groundwater from the Mississippi River Valley alluvial aquifer (MRVA), coincident with the Mississippi Alluvial Plain (MAP), is a vital resource for agriculture and drinking-water supplies in the central United States. 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...
