The dataset consists of a shapefile of measurements of surface velocity magnitude and direction at the Colorado River at Compact Point near Lees Ferry, AZ, on March 18, 2021. The dataset contains approximately 1.2 km of river length. The surface velocity measurements were made by applying Large-Scale Particle Image Velocimetry (LSPIV) techniques, using overlapping videos collected by small Unmanned Aircraft Systems (sUAS). Total time to capture all videos was less than one hour, and all frames (except frame 1, see Process Steps below) from all videos were used. Additional attributes, including divergence, curl, shear, and strain, were calculated from the surface velocity measurements and are included in the dataset.
For over 125 years, the U.S. Geological Survey streamgage network has provided important hydrologic information about rivers and streams throughout the Nation. Traditional streamgage methods provide reliable stage and streamflow data but typically only monitor stage at a single location in a river and require frequent calibration streamflow measurements. Direct measurements are not always feasible, therefore improved sensors and methods are being deployed at gages to better document streamflow conditions between measurements. The technology and techniques of reach-scale monitoring allow the U.S. Geological Survey to collect more data across the full range of streamflow without requiring that a hydrographer be present....
The dataset consists of a shapefile of measurements of surface velocity magnitude and direction at the Colorado River at Salt Wash near Moab, UT, on October 7, 2020. The dataset contains approximately 3 km of river length. The surface velocity measurements were made by applying Large-Scale Particle Image Velocimetry (LSPIV) techniques, using overlapping videos collected by small Unmanned Aircraft Systems (sUAS). Additional attributes were calculated from the surface velocity measurements and are included in the dataset.
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.
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.
A train derailment occurred in Marana, Arizona, on July 10, 2018. Runoff from a severe thunderstorm was flowing over the tracks at the time and may have contributed to the derailment. At the request of the Pima County Regional Flood Control District, USGS collected high-water marks for the flood event upstream from the derailment area.
365149109492300 - Laguna Creek below Dennehotso near Kayenta, AZ - 2020/06/02 Terrestrial Lidar Data
This is a terrestrial LiDAR laser scanner dataset of an intermittent waterway named Laguna Creek near the community of Dennehotso, AZ collected on June 2, 2020. The reach scanned for this study is located at the bridge where State Route 160 crosses the waterway. The river channel on the upstream side of the bridge has experienced bank erosion over recent years. A bank stabilization project was implemented by the Arizona Department of Transportation in 2018. This scan is intended to capture the condition of the bank in 2020 and be used to measure any changes to the bank protection that has occurred since the installation.. A Leica MS-60 Multistation was used for the laser scanner data collection. Multiple scans were...
Field measurements of water depth were acquired from a reach of the Colorado River near Lees Ferry, Arizona, March16-18, 2021, to support research on remote sensing of water depth from satellite images. The depth measurements included in this data release were obtained along a series of cross-sections using a SonTek RiverSurveyor M9 acoustic Doppler current profiler (ADCP) deployed from a boat. The spatial location of each measurement was obtained using a differential GPS included as part of the RiverSurveyor M9 ADCP instrument package. The map projection and datum for these data are UTM Zone 12S and WGS84, respectively. The USGS Qrev software program was used to ingest and process the raw ADCP data. The Qrev data...

The dataset contains GPS survey data collected at Colorado River at Salt Wash near Moab, UT, as part of a surface velocity mapping effort. The survey was conducted on June 9, 2020, and documents ground control points for a small unmanned aircraft system (sUAS) survey. The survey was performed using Leica GS14 RTK GPS equipment, S/N base-2806898, S/N rover-2806883.
The dataset contains data from two GPS surveys conducted after a flow event on September 8, 2020, at the USGS streamgage 09471580 - San Pedro River at St David, AZ. The first survey, conducted on October 14, 2020, documents CSA cross section geometry, CSA pin elevations, and high-water marks at CSA cross sections from the flow event in the CSA reach downstream from the gage (09471588 - San Pedro River below Dragoon Wash at St David, AZ). The second survey, conducted on December 8, 2020, documents CSA pin elevations and additional high-water marks in the CSA reach from the flow event on September 8, 2020, and the elevation of the thalweg from the CSA reach to the streamgage (09471580) at the bridge.
A GPS survey was conducted on June 12, 2019, to document the cross section geometry at the streamgage 09471580 - San Pedro River at St David, AZ, and CSA pin elevations and cross section geometry at the CSA sensor locations at CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ. One cross section was surveyed at streamgage 09471580 - San Pedro River at St David, AZ; and four CSA pin elevations and cross sections were surveyed at CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ.
