Data

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 capture a

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 Amargosa Wild

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 baseline co

This U.S Geological Survey data release contains soil moisture, actual evapotranspiration, precipitation, and potential evapotranspiration by watershed for the United States from 1980 to 2020. Hourly values from NASA's North American Land Data Assimilation System Phase 2 (NLDAS-2) Noah model were aggregated to daily values and extracted by Geospatial Attributes of Gages for Evaluating Streamflow,

This data set contains two sets of measured water-level data collected on and near Offutt Air Force Base near Bellevue, Nebraska. Surface-water and groundwater-level data were collected for two synoptic water-level surveys completed in late summer of 2020 and in spring 2021. The elevations of surface-water features were surveyed with a rover receiver using a real-time network (RTN), where the rove

This U.S. Geological Survey data release consists multiple datasets used to simulate the extents of flood inundation along the Muddy River, near Moapa, Nevada. Flood-inundation extents equal the maximum area of flood inundation and were estimated using a coupled one-dimensional (1D) and two-dimensional (2D) hydraulic model. The modeled extents represent six annual exceedance probabilities simulate

A 3-dimensional (3D) synthetic model, using MODFLOW-NWT and MT3D-USGS, explores the new unsaturated zone heat transport capabilities in MT3D-USGS. Model simulations were used to explore various parameter sensitivities and unsaturated zone thicknesses and their impact on heat transport as water enters the subsurface as infiltration, flows through the unsaturated zone to the water table, and eventua

A 3-dimensional (3D) synthetic model, built for running with MODFLOW-NWT and MT3D-USGS, explores the new unsaturated zone heat transport capabilities in MT3D-USGS. Model simulations explore potential responses to within a watershed to climate warming along system pathways. The response analysis uses output from a 30-year warming period on a synthetic watershed patterned after a humid temperate cli

Six hypothetical 1-dimensional models are used to verify and demonstrate new unsaturated-zone heat transport functionality added to MT3D-USGS (version 1.1.0). Because the governing equations describing groundwater solute transport and heat transport have a similar form, MT3D-USGS may be applied to heat transport problems. Published examples of MT3DMS, from which MT3D-USGS is derived, as a heat tra

A three-dimensional MODFLOW-NWT groundwater flow model was developed to evaluate the impacts of alternative water management scenarios on the groundwater resources of Eagle, Dayton, and Churchill Valleys, Nevada. In addition, the resulting impact on flows in the Carson River and Lahontan Reservoir are also evaluated. During the economic boom that occurred from 2004-2006 in northwestern Nevada, mun

The hydrograph for well ER-5-3-2 in Frenchman Flat, southern Nevada, has previously unexplained water-level fluctuations. Four, three-dimensional, groundwater models (MODFLOW 6) were developed to evaluate potential stresses and hydrologic conditions affecting the well ER-5-3-2 hydrograph. Four model scenarios were developed that simulated: (1) wellbore leakage without recharge, (2) wellbore leakag
