USGS-MAP-gwmodels provides a single code base for preprocessing input data to the USGS Mississippi Alluvial Plain (MAP) project groundwater models. Input data are derived from other components within the MAP project and from external sources such as the National Water Information System (NWIS). Preprocessed data are output in clean formats that are independent of a particular model grid, allowing the model discretization to be easily changed without rerunning the preprocessing. By having a single code base that is well tested and documented, we avoid the many of the potential errors and confusion that are inherent in ad-hoc scripting. A single code base also facilitates reproducability in the modeling workflow,...
These annual water-use rasters estimate the total amount of groundwater used for aquaculture and irrigation purposes within the Mississippi Alluvial Plain. This dataset contains 114 annual water-use rasters for 6 different categories: aquaculture, cotton, corn, rice, soybeans, and all other crops. Units are in cubic meters per square mile.
These monthly water-use rasters estimate the total amount of groundwater used for aquaculture and irrigation purposes within the Mississippi Alluvial Plain during the growing season (April-October). This dataset contains 798 monthly water-use rasters for 6 different categories: aquaculture, cotton, corn, rice, soybeans, and all other crops. Units are in cubic meters per square mile.
This dataset is the raster, in meters, of the potentiometric-surface map, spring 2020, Mississippi River Valley alluvial aquifer (MRVA). The raster cell size is 1,000 meters; the raster was referenced to the North American Vertical Datum of 1988 (NAVD 88). The raster, in feet, was interpolated using most of the available groundwater-altitude (GWA) data from wells, surface-water-altitude (SWA) data from streamgages, and the potentiometric contours. Then the raster altitude data was converted to meters.
Towed transient electromagnetic (tTEM) data were acquired along levees at select area near Vicksburg, Mississippi during March 2018. During the survey, 13.7 line-kilometers were collected in the focus area. Data were collected by members of the U.S. Geological Survey, Technology Development and Transfer Team, and the Aarhus University Hydrogeophysics Group. tTEM data acquired along the approximately 14 line-kilometers atop and along the toe of a levee near the banks of the Mississippi River in Warren County, Mississippi. Data were collected to characterize the subsurface resistivity structure of levees in support of a technical demonstration for the U.S. Army Corps of Engineers. tTEM data were collected using an...
Airborne electromagnetic (AEM), magnetic, and radiometric data were acquired in late February to early March 2018 along 2,364 line-kilometers in the Shellmound, Mississippi study area. Data were acquired by CGG Canada Services, Ltd. with three different helicopter-borne sensors: the CGG Canada Services, Ltd. RESOLVE frequency-domain AEM instrument that is used to map subsurface geologic structure at depths up to 100 meters, depending on the subsurface resistivity; a Scintrex CS-3 cesium vapor magnetometer that detects changes in deep (hundreds of meters to kilometers) geologic structure based on variations in the magnetic properties of different formations; and a Radiation Solutions RS-500 spectrometer that detects...

Electrical resistivity results from four regional airborne electromagnetic (AEM) surveys (Burton et al. 2024, Hoogenboom et al. 2023, Minsley et al. 2021, Burton et al. 2021) over the Mississippi Alluvial Plain (MAP) were combined by the U.S. Geological Survey (USGS) to produce three-dimensional (3D) gridded models and derivative hydrogeologic products. The 3D models and products were first published using data from the earlier two AEM regional surveys, labeled with the year “2020” (Minsley et al. 2021, Burton et al. 2021). The 3D resistivity models and select derivative products were later updated by incorporating additional data from the two later AEM surveys, labeled with the year “2022” (Burton et al. 2024,...
Datasets are inputs and outputs of Aquaculture and Irrigation Water Use Model (AIWUM) 2.0. AIWUM 2.0 employs remote sensing data sets and machine learning utilizing Distributed Random Forests, an ensemble machine learning algorithm to estimate annual and monthly groundwater use for irrigation and aquaculture (2014–20) throughout this region at 1 km resolution, using annual pumping data from flowmeters in Mississippi and real-time flowmeters in Arkansas, Louisiana, Mississippi, Missouri, and Tennessee. Aquaculture and irrigation estimates contained in this data release are representative of groundwater withdrawal for six different categories: aquaculture, cotton, corn, rice, soybeans, and other crops. Model results...
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...

Electrical resistivity results from four regional airborne electromagnetic (AEM) surveys (Burton et al. 2024, Hoogenboom et al. 2023, Minsley et al. 2021, Burton et al. 2021) over the Mississippi Alluvial Plain (MAP) were combined by the U.S. Geological Survey (USGS) to produce three-dimensional (3D) gridded models and derivative hydrogeologic products. The 3D elevation grid was used to quantify across the MAP region 1) the occurrence and thickness of surficial (< 15 meter (m) depth) confining material, 2) the top and bottom elevation corresponding to the surficial confining material, and 3) a metric representing the degree of surface confinement or connectivity that ranges from fully confining conditions to high...
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...
The Mississippi Alluvial Plain (MAP) has become one of the most important agricultural regions in the US, and it relies heavily on a groundwater system that is poorly understood and shows signs of substantial change. The heavy use of the available groundwater resources has resulted in significant groundwater-level declines and reductions in base flow in streams within the MAP. These impacts are limiting well production and threatening future water-availability for the region. This product will help not only scientists in our center, but also at a national level. This product will also be part of a larger study encompassing the Mississippi Alluvial Plain region. The Mississippi Alluvial Plain extent was delineated...

Evapotranspiration (ET) is a key component of the hydrologic cycle, accounting for ~70% of precipitation in the conterminous U.S. (CONUS), but it has been a challenge to predict accurately across different spatio-temporal scales. The increasing availability of remotely sensed data has led to significant advances in the frequency and spatial resolution of ET estimates, derived from energy balance principles with variables such as temperature used to estimate surface latent heat flux. Although remote sensing methods excel at depicting spatial and temporal variability, estimation of ET independently of other water budget components can lead to inconsistency with other budget terms. Methods that rely on ground-based...
