This point shapefile represents 38 terrestrial laser scanner (TLS) survey scan locations collected by single-base real-time kinematic (RTK) global navigation satellite system (GNSS) surveys in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. Data were collected by two Topcon GR-3 GNSS receivers at one-second intervals for three minutes for each location.
This polygon shapefile represents estimated flood-inundation areas in Grapevine Canyon near Scotty's Castle, Death Valley National Park. Estimates of the 4, 2, 1, 0.5, and 0.2 percent annual exceedance probability (AEP) flood streamflows (previously known as the 25, 50, 100, 250, and 500-year floods) were computed from regional flood regression equations. The estimated flood streamflows were used with one-dimensional hydraulic models to compute water surface elevations that were mapped on a digital terrain model of the study area. Those locations where the water surface was higher than the land surface were defined as inundated. The inundation polygons are named by AEP flow (4, 2, 1, 0.5, 0.2-percent) and geometry...

This point shapefile represents ground observations collected by terrestrial laser scanner (TLS) surveys in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016, and filtered of extraneous data from features such as vegetation, fences, power lines, and atmospheric interference using an iterative process in I-Site Studio. The resulting 122,104 points were used to produce a digital terrain model of the area (GrapevineCanyon_TIN.zip in this data release).

Over the past 15 years Douglas County, NV has removed production wells in northern Carson Valley from use due to relatively high arsenic concentrations (Carl Ruschmeyer, January 2013, Douglas County Public Works Director, verbal communication). To maintain the supply of water to the public, the town of Minden has been providing water to Douglas County and Carson City. Due to the projected increases in municipal demand, water resource managers are concerned that increasing pumping rates from wells in Minden may change groundwater chemistry and degrade the resource by potentially drawing in arsenic enriched water. Naturally occurring arsenic is one of the most common contaminants in groundwater in the western United...
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.
This zip file contains 42 LAZ point cloud files surveyed by terrestrial laser scanner (TLS) from 38 locations in Grapevine Canyon near Scotty’s Castle, Death Valley National Park, from July 12-14, 2016. Data were collected by 360-degree scans using a Maptek I-Site 8810XR TLS and post-processed with I-Site Studio software.
This point shapefile represents four static reference locations collected by single-baseline Online Positioning User Service – Static (OPUS-S) global navigations satellite system (GNSS) surveys in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. Surveys were completed at three Federal Highway Administration benchmarks (FHWA) and one temporary reference point, Rebar1. Data were collected using Topcon GR-3 and Leica Viva GS14 GNSS receivers on two-meter fixed height tripods. Processing of static observations was done using the National Geodetic Survey (NGS) Online Positioning User System (OPUS).
This U.S. Geological Survey data release consists of a polygon geospatial dataset representing estimated flood-inundation areas in Grapevine Canyon near Scotty's Castle, Death Valley National Park, and the data acquired and processed to support the delineation of those areas. Supporting datasets include topographic survey data collected by global navigation satellite system (GNSS) and terrestrial laser scanner (TLS) in Grapevine Canyon from July 12-14, 2016; derivatives of those data; pebble count data collected in Grapevine Canyon; and an archive of the one-dimensional hydraulic model used to generate the flood-inundation area polygons. Specifically: 1)a point dataset of four static reference locations (StaticGNSS_x)...
This point shapefile represents 769 locations surveyed by single-base real-time kinematic (RTK) global navigation satellite system (GNSS) in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. The points were collected at 3-second intervals and include hard and soft surfaces and slopes throughout the study area. The points were used as vertical precision verification for a terrestrial laser scanner (TLS) survey.
This comma-separated values (CSV) file includes the results of five Wohlman-style pebble counts (Wolman, 1954), collected in Grapevine Canyon near Scotty's Castle, Death Valley National Park, on March 2, 2017. Pebble counts were performed to determine the size of channel bed particles and evaluate channel roughness to be input into a one-dimensional hydraulic model.

These data comprise air, plant (creosote bush, Larrea tridentata), and unsaturated-zone tritium measurements and plant metrics collected during 2012 to 2016 from three sampling areas at the Amargosa Desert Research Site (ADRS) near Beatty, Nevada: (1) within a low-level radioactive waste facility, (2) buffer area adjacent to the waste facility, and (3) reference area 3 kilometers from the waste facility. Plant metrics include foliage-water content and canopy and stem dimensions. Supporting information includes a list of publications that provide descriptions of methods used to collect the data and results of previous tritium research at the ADRS. All data and supporting information are compiled in an electronic...
These data represent the extent and spatial distribution of irrigated acreage delineated from maximum Normalized Difference Vegetation Index (NDVI) derived from Landsat scenes in the Walker River Basin, California and Nevada, at five-year intervals from 1975-2010. The field boundaries in this data set are digitized from one-year composite maximum NDVI data derived from atmospherically corrected Landsat 2 Multispectral Scanner (MSS), Landsat 5 MSS, and Landsat 5 Thematic Mapper (TM) scenes. NDVI was calculated from the corrected reflectance data for each selected scene during the growing season (May through early October) and a single, composite image of maximum NDVI values was derived for each 5-year interval. Selecting...
