D'Agnese and others (1998) developed a potentiometric surface to conceptualize the regional ground-water flow system and to construct numerical flow models of the Death Valley region, Nevada and...
-
A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well...
-
These data were compiled to improve our understanding of bat foraging along the Colorado River in Grand Canyon. Objectives of our study were to determine whether bat activity was influenced...
-
Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. This dataset presents latitude, longitude, altitude, and...
-
A digital three-dimensional (3D) hydrogeologic framework model (HFM) represents the geometry and extent of hydrogeologic units (HGUs) and major structures in the Death Valley regional...
-
We developed an approach to quantify Urban Heat Island (UHI) extent and intensity in 50 cities of CONUS and its surrounding area by using surface temperature from Landsat surface temperature...

This line vector dataset represents initial groundwater head contours used as input data for the Rio Grande transboundary integrated hydrologic model and water-availability analysis, New Mexico...
-
This digital data set defines the subregions of the transient ground-water flow model of the Death Valley regional ground-water flow system (DVRFS). Subregions are used to more readily describe...

These simulated potentiometric surface contours represent prepumping (or steady-state) conditions for model layer 16 of the Death Valley regional ground-water flow system (DVRFS), an...
-
This dataset contains annual Rio Grande Project surface-water allotments and diversion allocations from 1940 through 2014 to lands within New Mexico, Texas, and Mexico. Allotment and allocation...

These contours represent the simulated potentiometric surface at the end of simulation (1998) in model layer 16 of the Death Valley regional ground-water flow system (DVRFS), an approximately...
-
This point feature class contains 81,481 points arranged in a 270-meter spaced grid that covers the Spring Mountains and Sheep Range in Clark County, Nevada. Points are attributed with...
-
This data release presents data used for analyzing spatial and temporal differences in soil surface roughness within selected biocrust communities. These records were collected by ground-based...
-
This digital geospatial data set is a compilation of reference points representing springs in Nevada that were used for the regional ground-water potential map by Bedinger and Harrill (2004). ...
-
This digital dataset represents the surface hydrogeology of an approximately 45,000 square-kilometer area of the Death Valley regional ground-water flow system (DVRFS) in southern Nevada and...
-
The elevation contours in this dataset have a 2-foot (ft) interval and were derived from a digital elevation model (DEM) of beach topography and nearshore bathymetry of Lake Superior at Minnesota...
-
This tabular dataset contains the location and construction information of select wells in the Albuquerque area, central New Mexico, and groundwater-level measurements at those wells from 2014 to...
