Data

This data release contains two MODFLOW 6 simulations. Each simulation contains one groundwater flow (GWF) model and one groundwater energy (heat) (GWE) transport model. The GWF and GWE models are constructed to match the setup of the Barends analytical solution for two-dimensional heat transport. This allows the accuracy of the new GWE model to be verified so existing and prospective...

This U.S. Geological Survey data release presents raster geospatial data of modeled estimates of average total annual evapotranspiration by groundwater (ETg) and recharge (RCH), in millimeters, for Kenya for 2000 through 2022. Estimates were calculated by differencing Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) 2.0 precipitation data and Moderate Resolution...

This U.S. Geological Survey data release contains data from soil and storm water samples collected in and around areas in southern Nevada where a polymer-based dust palliative was applied. The applied palliatives were FSB-1000 (Soil Tech, 2012) or Soil-Sement (Midwest Industrial Supply, Inc., 2001) which contain water and the co-polymer butyl acrylate vinyl acetate (BAVA). Samples were...

This data release contains raster geospatial data for characterizing drainage basins in the Nevada StreamStats study area. Included are precipitation, temperature, elevation, slope, and land cover data. There are 70 full or partial 8-digit hydrologic units (HU8) represented in the Nevada StreamStats study area: 15010005 (partial), 15010006 (partial), 15010008, 15010009, 15010010...

This data release contains vector and raster geospatial data for delineating drainage basins in the Nevada StreamStats study area. Included are vector streamline, waterbody, and inner wall data used to hydrologically condition the digital elevation model. The hydrologically-conditioned digital elevation model, flow direction, flow accumulation, and stream delineation raster data are also...

This vector data set represents the evapotranspiration (ET) discharge quantification area polygon in the lower Walker River basin.

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They...

This data release contains MODFLOW 6 integrated hydrological model (IHM) that helps characterize the groundwater/surface-water interaction within the Sardon Catchment of western Spain. The model was used to quantify and reduce the overall model uncertainty to improve its reliability as a Decision Support Modeling (DSM) tool by improving the conceptualization and simulation of the...

This USGS data release represents the data from the following 2013 publication: Plume, R.W., and Smith, J.L., 2013, Properties of basin-fill deposits, a 1971–2000 water budget, and surface-water-groundwater interactions in the upper Humboldt River basin, northeastern Nevada: U.S. Geological Survey Scientific Investigations Report 2013-5077, https://doi.org/10.3133/sir20135077.

A three-dimensional groundwater flow model using MODFLOW-NWT was developed to evaluate historical and potential stream capture in the lower Humboldt River Basin, Nevada. The Humboldt River Basin is the only river basin that is contained entirely within the state of Nevada. The effect of groundwater pumping on the Humboldt River is not well understood. Tools are needed to determine stream...

This data release supports U.S. Geological Survey Scientific Investigations Report 2023-5106, Groundwater Discharge by Evapotranspiration from the Amargosa Wild and Scenic River and Contributing Areas, Inyo and San Bernardino Counties, California. Geospatial datasets presented are two polygon shapefiles representing the groundwater discharge areas and evapotranspiration units for the...

A proof-of-concept MODFLOW 6 groundwater model was developed to represent the bedrock, delta, and alluvially-deposited aquifers underlying the Mekong River Basin approximately between Phnom Penh, Cambodia and Cao Lanh, Vietnam. The model was constructed using square grid cells measuring 2,200 meters on each side. The proof-of-concept groundwater model was used to simulate environmental...
