Geospatial data, flood-frequency analysis, and surface-water model archive for streamflow extents and hydraulic characteristics of Meadow Valley Wash at Stuart Ranch, near Rox, Nevada

This U.S. Geological Survey data release consists of multiple datasets used to simulate the streamflow extents and hydraulic characteristics of Meadow Valley Wash at Stuart Ranch near Rox, Nevada. Streamflow extents equal the maximum area of flow inundation and were estimated using a two-dimensional (2D) hydraulic model. The modeled extents represent baseflow and six annual exceedance probabilities simulated for the current (2021) topography and modified topography associated with possible restoration of Stuart Ranch along Meadow Valley Wash. The data release includes:
1) a zip file containing a shapefile of a polygon dataset of the streamflow-inundation extents (Stuart_streamflow_extent.shp);
2) a zip file containing all raster datasets of streamflow depth (Stuart_Depth.zip);
3) a zip file containing all raster datasets of streamflow velocity (Stuart_Velocity.zip);
4) a zip file containing all relevant files to document and run the PeakFQ flood-frequency analysis used as input into the hydraulic model (09418700_Stuart_Flood_Frequency_Archive.zip);
5) a zip file containing all relevant files to document and run the 2D Hydrological Engineering Center-River Analysis System (HEC-RAS) hydraulic model used to generate a polygon dataset of streamflow-inundation extents (Stuart_SWmodel_Archive.zip);
6) a zip file containing a raster dataset of a digital elevation model (Stuart_DEM.tif) derived from survey points;
7) a zip file containing two polygon datasets of the restoration modifications used in conjunction with the Stuart_DEM to model possible restoration conditions (Beaver_Dam_Modification.shp and SideChannels_IrrigationDig_Modifications.shp);
8) a zip file containing a point dataset of survey points (SurveyData.shp) collected from December 14, 2020 to January 11, 2024, using real-time kinematic global navigation satellite system (GNSS), static GNSS, total station (TS), manual entries, and filtered ground observations from TLS surveys; and
9) a point dataset of lidar points (Stuart_Raw_TLS.las) collected at 44 scan locations by TLS surveys.
