The dataset consists of a .csv and shapefile of measurements of surface velocity magnitude and direction at the Colorado River at Windy Gap near Granby, CO, on June 13, 2022. The dataset contains approximately 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). Additional attributes, including divergence, curl, shear, and strain, were calculated from the surface velocity measurements and are included in the dataset. This data is ideal for instantaneous discharge, shear, strain, and divergence, but less so for eddies and mean reach values. This is because...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
