The U.S. Geological Survey collected field spectra collected from three rivers in Alaska September 19–21, 2016, to support research on remote sensing of river discharge. Reflectance measurements were made from bridges across the Chena River, Salcha River, and Montana Creek using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The original *.asd files are provided in this data release. This data release supports the following article: Legleiter, C.J., Kinzel, P.J., and Nelson, J.M., 2017, Remote measurement of river discharge using thermal particle image velocimetry (PIV) and various sources of bathymetric information: Journal of Hydrology, v. 554, p. 490-506, https://doi.org/10.1016/j.jhydrol.2017.09.004.

Field measurements of water depth were acquired from a reach of the upper Sacramento River in northern California, September 12-14, 2017, to support research on salmon habitat and geomorphic change along the Sacramento River and, more broadly, remote sensing of rivers. The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the water's edge and bed elevations within the channel; depths were calculated by subtracting bed elevations from the nearest water surface elevation. For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor...

Field spectra were collected from the Deschutes River near Bend, OR, July 26-28, 2016, to support research on remote sensing of river discharge. Reflectance measurements were made from a raft in the reach of the Deschutes River between Benham Falls and Dillon Falls using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The depth at each spectral measurement location was interpolated from field measurements of depth obtained with an echo sounder. This data release provides both the reflectance spectra and the interpolated depths and can be used to develop relationships between depth and reflectance for mapping river bathymetry from field spectra or passive optical remotely...

A reach of the North Santiam River, Oregon, was used as a case study in an ongoing effort to develop and test image velocimetry algorithms for estimating surface flow velocities in river channels from remotely sensed data. Video was acquired from an unoccupied aircraft system, UAS, and used as input to the image velocimetry algorithms. Direct measurements of flow velocity were obtained using an acoustic Doppler current profiler, ADCP, and used to assess the accuracy of the image velocimetry algorithms. The UAS-based video was acquired from a DJI Matrice 210 quadcopter equipped with a Zenmuse X4S optical camera on July 25, 2022. The video is provided in its native form, with a frame rate of 30 Hertz and an *.mov...

A vertical profile of downwelling spectral irradiance at different depths within the water column was measured on the Deschutes River near Bend, OR, July 28, 2016, to support research on remote sensing of river discharge. Downwelling spectral irradiance data were collected using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in irradiance mode and deployed from a customized measurement crane. The measurements were made near a boat launch downstream of Benham Falls. In addition, the depth at which each downwelling spectral irradiance measurement was made was obtained using an Onset Hobo pressure transducer mounted next to the spectroradiometer foreoptic on the crane. This data release provides...

Field spectra were collected from the Snake River in Grand Teton National Park, WY, August 23, 2015, to support research on remote sensing of rivers. Reflectance measurements were made from a raft in the Swallow Bend reach of the Snake River using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The depth at each spectral measurement location was interpolated from field measurements of depth obtained with an acoustic Doppler current profiler. This data release provides both the reflectance spectra and the interpolated depths and can be used to develop relationships between depth and reflectance for mapping river bathymetry from field spectra or passive optical remotely sensed...

This data release includes the data and code used for the paper titled "A framework to facilitate development and testing of image-based river velocimetry algorithms", published in the journal Earth Surface Processes and Landforms. Three *.csv files and five *.m files with MATLAB source code are included below. Each *.csv file contains output from a hydrodynamic model of a reach of the Sacramento River near Glenn, California, with a separate file for each of three different discharges (i.e., streamflow rates): 90, 191, and 255 cubic meters per second. The hydrodynamic model used for this purpose was the Nays2DH solver available within the International River Cooperative Interface (iRIC). Provided below is a link...

The U.S. Geological Survey collected field spectra collected from the Niobrara River in Nebraska August 15–18, 2016, to support research on remote sensing of river discharge. Reflectance measurements were made by wading the Niobrara River near Norden Notch using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The original *.asd files are provided in this data release.

Force gage measurements were used to parameterize a force balance model for the initiation of sediment motion and thus characterize bed mobility for two reaches of the lower Merced River in California's Central Valley. These data were acquired to support research intended to evaluate the extent to which large-scale restoration projects provided improved salmon spawning habitat. A related goal of this study was to improve our understanding of the geomorphic factors influencing spawning site selection by salmon. The force gage measurements were made at the Merced River Ranch and Robinson Reach field sites and involved using a spring-resisting force gage to push a given submerged particle in a bed-parallel downstream...
