This data release consists of a set of tiled orthophotos of the Salcha River in Alaska acquired on July 25, 2019. The orthophotos were produced from images obtained using a Hasselblad A6D-100C 100 megapixel digital mapping camera deployed within a pod mounted on the landing gear of a Robinson R44 helicopter. Images were acquired as the helicopter transited a series of flight lines designed to provide complete coverage, with ample overlap, of the study area along the Salcha River. Also within the pod was an ATLANS GPS/Inertial Motion Unit (IMU) that recorded the position and orientation of the platform during the flight. This information was used to geo-reference the images by performing aerial triangulation and...

The U.S. Geological Survey conducted a bathymetric survey of a reach of the Deschutes River near Bend, OR, between Benham Falls and Dillon Falls on July 25, 2016, to support research on remote sensing of river discharge and characterization of habitat for amphibians, particularly the Oregon Spotted Frog (Rana pretiosa). The bathymetric survey data were obtained with an ITER Systems Bathyswath-1 468 kHz multi-beam echo sounder deployed from a customized research cataraft. The Bathyswath Swath Processor software package was used to acquire the raw data, which then were post-processed, filtered, and gridded using the Bathyswath Grid Processor program. The final output file included in this data release consists of...

Bathymetric and topographic surveys were collected along an approximately 5.7-kilometer reach of the Colorado River upstream from the USGS streamgage located near the Colorado River Road (Catamount) bridge. The surveys were collected using real-time kinematic Global Navigation Satellite System (GNSS) receivers by USGS personnel between May 13 through September 9, 2021, using a combination of sonar and wading techniques. The wading surveys include point data that are provided as comma-delimited text files of northing, easting, elevation, and code. The sonar surveys include point data that are provided as comma-delimited text files of northing, easting, bed elevation, water-surface elevation, and depth. All spatial...
Optical measurements collected from the Colorado River, near Lees Ferry, Arizona, September 23, 2019
To support an investigation of the feasibility of measuring river bathymetry using a polarizing lidar sensor, optical measurements were collected from the Colorado River near Lees Ferry, Arizona on September 23, 2019. Optical measurements were collected with a WET Labs ECO which measures the turbidity and concentration of colored dissolved organic matter (CDOM) and chlorophyll. Absorption and attenuation coefficients were collected with a WET Lab ac-s instrument.

Twenty one submersible pressure transducers were deployed along the Green River near Jensen Utah in late February 2018. At some locations two transducers were deployed at different elevations to capture the expected range of water level fluctuations, an "upper" and "lower" transducer. Two additional transducers were left out of the water to correct for barometric pressure fluctuations. At the time of deployment, the position of a reference point located on a t-post to which each transducer was mounted was measured with real-time kinematic GPS equipment. In addition, a tape down or the distance between the reference point to the water surface was recorded.The transducers collected a depth measurement every 15 minutes...

A Bell 407 helicopter with a gyro-stabilized gimbal was used to collect aerial videos of Illinois River Water Science basin riverine study sites on June 7, 2022. Videos were collected during three flights on June 7, 2022 and focused on study sites along the Illinois River near Starved Rock. The videos are in a natural color camera channel (CH_1) and a thermal infrared camera channel (CH_2).
This data release consists of a series of videos used to derive remotely sensed estimates of surface flow velocity via particle image velocimetry (PIV). These data were acquired from the Tanana River near Nenana, Alaska, on July 24, 2019, along with field measurements of flow velocity used to assess the accuracy of image-derived velocity estimates. The videos were obtained using a Zenmuse X5 video camera deployed within a Meeker mount attached to the nose of a Robinson R44 helicopter. The data release includes a total of 14 individual videos obtained while the helicopter hovered at a series of different locations above the river channel to provide reach-scale coverage. Each of these videos was recorded at 30 frames...
This archive contains results of flow and sediment transport simulations of a reach of the Middle Channel of the St. Clair River delta, Michigan using the iRIC modeling system and the Flow and Sediment Transport with Morphologic Evolution of Channels (FASTMECH) solver. Two hydraulic model simulations were used to determine lateral eddy viscosity and roughness settings. A third simulation contains results of the Wilcox-Kenworthy (WK) two-fraction sediment transport model. The WK model was used to simulate the movement of fine grained sediment into coarser immobile substrate. The coarse rock rubble substrate (reefs) constructed in the Middle Channel in 2012 began filling with sand within a year. However, detailed...

Evaluating technologies and approaches to detect the infiltration of fines into coarser materials has implications for monitoring the condition of habitat restoration sites. This goal motivated testing the efficacy of Fiber Optic Distributed Temperature Sensing (FO-DTS) as a technique for detecting the infiltration of fine sediment into gravels. Experiments were conducted in a laboratory flume at the USGS Geomorphology and Sediment Transport Laboratory (GSTL) in Golden, Colorado. A 10 meter fiber optic cable was placed in the flume with one half of the cable buried approximately 6 centimeters in a substrate (gravel, sand, and mixtures of the two) along the length of the flume, while the other half was placed at...

The U.S. Geological Survey in collaboration with the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL) collected topographic LiDAR surveys of four rivers in Alaska from August 8-9, 2017 to support research related to remote sensing of river discharge. Data were acquired for the Knik, Matanuska, Chena and Salcha Rivers using a Riegl VQ-580 LiDAR. The LiDAR was installed on a Robinson R44 Raven helicopter in a HeliPod that was designed and operated by CRREL. The LiDAR data included as part of this release include: a bare earth digital elevation model (DEM), an intensity or reflectence digital surface model (DSM) both in GeoTiff format, and compressed binary LAS files (LAZ) for each...

A topographic and bathymetric survey was collected along a reach of the Green River downstream of Dinosaur National Monument. The surveyed reach extends approximately 16 kilometers upstream and 6 kilometers downstream of the U.S. Route 40 bridge near Jensen, Utah. The topographic and bathymetric data include survey point data for 382 cross sections over 22 kilometers and are provided as a text file of easting, northing and elevation, in meters. The cross-section location data were collected using real-time kinematic Global Navigation Satellite Systems (GNSS) by USGS personnel from March 26, 2018, through March 29, 2018 using a combination of Sound Navigation and Ranging (SONAR) and wading techniques.

Field measurements of depth-averaged flow velocity and water depth were acquired from the Tanana River near Nenana, Alaska, August 18, 2021, to support research on estimating surface flow velocities and water depths from remotely sensed data. The depth and velocity measurements included in this data release were obtained using a TRDI RiverRay acoustic Doppler current profiler (ADCP) deployed from a boat with an outboard motor. These data were collected along 8 cross-sections on the Tanana River; two passes across the channel were made at each cross-section. This data release provides depth-averaged flow velocities and total flow depths derived from the raw ADCP data using the TRDI WinRiver II processing software....

This data release includes a video acquired from a satellite and field measurements of flow velocity from the Tanana River in Alaska that were used to derive remotely sensed estimates of surface flow velocities via particle image velocimetry (PIV). The field data were collected on July 24, 2019, in cooperation with the USGS Alaska Science Center, and the satellite video was obtained on July 14, 2020. The purpose of this study was to assess the feasibility of inferring flow velocities from video acquired from a satellite in orbit above the river by tracking water surface features via a Particle Image Velocimetry (PIV) algorithm. Remote sensing of flow velocity could provide a more efficient, cost-effective alternative...
