Geospatial data and surface-water model archive for evaluation of streamflow extent and hydraulic characteristics of a restored channel at Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada
Description
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 dataset of the filled and excavated channel locations (Channel_Modification_p.zip);
2) a digital elevation model (SoldierMeadows_TIN.zip) edited for proposed restoration work as a triangulated irregular network (TIN) in North American Vertical Datum of 1988;
3) a point dataset of 476 points (RTKSurvey_x.zip) collected using real-time kinematic GNSS surveys;
4) a point dataset of one static reference location (StaticGNSS_x.zip) collected using a single-baseline online positioning user service – static (OPUS-S) GNSS survey;
5) a raster dataset of the streamflow depth (SoldierMeadowsStreamflowDepth.zip);
6) a polygon dataset of the streamflow extent (SoldierMeadowsStreamflowExtent_p.zip);
7) a rater dataset of the streamflow velocity (SoldierMeadowsStreamflowVelocity.zip;
8) a zip file containing all relevant files to document and run the Hydrological Engineering Center-River Analysis System (HEC-RAS) two dimensional hydraulic model used to generate a polygon dataset of streamflow extent and raster datasets of stream velocity and stream depth (SWmodel_Archive.zip);
