This U.S. Geological Survey data release consists of a geospatial dataset containing information on estimated streamflow extent, stream velocity, and stream depth at Soldier Meadows Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada, and the data acquired and processed to support the estimation of those attributes. Supporting datasets include topographic survey data collected using a global navigation satellite system (GNSS) in Soldier Meadows from August 13-15, 2019, and an archive of the two-dimensional hydraulic model used to generate a polygon dataset for streamflow extent as well as raster datasets for stream velocity, and stream depth. The data release includes: 1) a polygon...
A digital elevation model represented by a triangulated irregular network (TIN) was developed for proposed channel restoration at Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. The TIN was derived from lidar (light imaging, detection, and ranging) of quality level 1 collected in April 2018 by Quantum Spatial (Quantum Spatial Inc, 2018) for the Bureau of Land Management. The DEM also includes points surveyed in August 13-16, 2019, using a real-time kinematic (RTK) global navigation satellite system (GNSS). The lidar data are not included in this USGS publication due to BLM data-release restrictions for this dataset. Contact Bureau of Land Management, Nevada,...
This point shapefile contains information on 476 locations surveyed using a single-base real-time kinematic (RTK) global navigation satellite system (GNSS) in Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada, August 14-15, 2019. The points were collected at 30-second intervals at control points and hydraulic structures and 5-second intervals at topographic points throughout the study area. The points were used as vertical precision verification for lidar data, editing the triangulated irregular network in locations of dense vegetation and surface water, locating streamflow measurement sites, creating hydraulic structures in the hydraulic model, and determining...
This polygon shapefile contains information on estimated streamflow extent for proposed channel restoration at Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. Streamflow extents were estimated by differencing water-surface elevations computed using a two-dimensional hydraulic model from mapped land surface elevations using a digital elevation model of the study area.
This digital raster dataset contains information on estimated streamflow depth for proposed channel restoration at Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. Streamflow depths were estimated by differencing water-surface elevations computed using a two-dimensional hydraulic model from mapped land-surface elevations using a digital elevation model of the study area.
This digital raster dataset contains information on estimated streamflow velocity for proposed channel restoration at Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. Streamflow velocities were estimated using a two-dimensional hydraulic model.
A triangulated irregular network (TIN) developed to create a digital elevation model was modified to represent areas of proposed channel modification at Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. This polygon shapefile contains the TIN modifications for locations of selected channels and ditches to be infilled or excavated for proposed restoration.
This U.S. Geological Survey data release consists of a tabular dataset containing stream temperature data. Data were collected every 12-hours from 15 sites in Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. The sites were established by the Bureau of Land Management - Winnemucca District Office in 2017. The data release includes tabular data of site names, date and time of temperature measurement, and stream temperature in degrees Celsius. The site locations are included below as a shapefile, exported from the National Water Information System (NWIS) Mapper. A site list can be accessed here: National Water Information System site list
This model archive contains all relevant files to document and run the Hydrological Engineering Center-River Analysis System (HEC-RAS) two dimensional hydraulic model used to simulate streamflow extent, depth, and velocity under proposed restoration at Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. The model archive includes information on: 1) The modeling software version and website (model-software-version.txt) 2) The model documentation report, data release, and bounding box coordinates (modelgeoref.txt) 3) How to run the model (model_run_files) 4) Selected model output from the model runs (model_output folder) 5) Water surface elevations surveyed on...
This point shapefile contains information on one static reference location collected using three single-baseline online positioning user service – static (OPUS-S) global navigation satellite system (GNSS) surveys in Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada, August 13-15, 2019. Surveys were completed at one temporary benchmark, TBM1. Data were collected by a Leica Viva GS14 GNSS. Processing of static observations was done using the National Geodetic Survey (NGS) online positioning user system (OPUS).
