The mapped area boundary, flood inundation extents, and depth rasters were created to provide an estimated extent of flood inundation along the Greenbrier River within the community of Alderson, West Virginia. These geospatial data include the following items: 1. greenbrier_ald_bnd; shapefile containing the polygon showing the mapped area boundary for the Greenbrier River flood maps, 2. greenbrier_ald_hwm; shapefile containing high-water mark points, 3. polygon_greenbrier_ald_hwm; shapefile containing mapped extent of flood inundation, derived from the water-surface elevation surveyed at high-water marks, 4. depth_hwm; raster file for the flood depths derived from the water-surface elevation surveyed at high-water...

Hurricane Harvey made landfall near Rockport, Texas on August 25 as a category 4 hurricane with wind gusts exceeding 150 miles per hour. As Harvey moved inland the forward motion of the storm slowed down and produced tremendous rainfall amounts to southeastern Texas and southwestern Louisiana. Historic flooding occurred in Texas and Louisiana as a result of the widespread, heavy rainfall over an 8-day period in Louisiana in August and September 2017. Following the storm event, U.S. Geological Survey (USGS) hydrographers recovered and documented 2,123 high-water marks in Texas, noting location and height of the water above land surface. Many of these high-water marks were used to create flood-inundation maps for...

The dataset contains GPS survey data from two surveys conducted after a flow event on September 19, 2018, at the USGS streamgage 09487000 - Brawley Wash near Three Points, AZ. The first survey, on October 1, 2018, documents cross section geometry and high-water marks from the flow event in the reach downstream from the gage. The second survey, on January 31, 2019, documents additional high-water marks and provides ground control for a small unmanned aircraft system survey. The surveys were performed using Leica GS14 RTK GPS equipment, S/N base-2806898, S/N rover-2806883.

The dataset contains GPS survey data from the second of two surveys conducted after a high flow event on August 20, 2018, at the USGS streamgage 04087088 - Underwood Creek at Wauwatosa, WI. This survey, on July 17, 2019, documents cross section geometry. The survey was performed using Trimble R10 RTK GPS unit (SN: 5326439561) and Trimble S7 Robotic Total Station (SN: 37430018).

These polygon boundaries, inundation extents, and depth rasters were created to provide an extent of flood inundation along the Lumber River within the community of Fair Bluff, North Carolina. The upstream and downstream reach extent is determined by the location of high-water marks, not extending the boundary far past the outermost high-water marks. In areas of uncertainty of flood extent, the model boundary is lined up with the flood inundation polygon extent. This boundary polygon was used to extract the final flood inundation polygon and depth layer from the flood water surface raster file. The passage of Hurricane Matthew through central and eastern North Carolina during October 7-9, 2016, brought heavy rainfall...

Continuous slope-area sensors are installed at four cross sections downstream from Flume 6 operated by the Agricultural Research Service (ARS) at the Walnut Gulch Experimental Watershed. The CSA reach was installed to test the CSA method and determine channel roughness using the known discharge measured by Flume 6. A flow event occurred on July 28, 2017. A GPS survey was conducted on August 2, 2017, to document the CSA pin elevations, cross section geometry at the CSA sensor locations, and high-water marks from the flow event.
