Summary

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.

Purpose

The data were collected to fulfill the objectives of a proposal funded by the U.S. Department of the Interior (DOI) Inland Oil Spill Preparedness Project (IOSPP). Reach-scale measurements of water surface velocity magnitude and direction can be used to predict the travel time of the leading edge of contamination and identifying areas where contaminants will accumulate during riverine oil spills, increasing the readiness and response capabilities of DOI in the event of an inland oil spill. This dataset, on March 18, 2021, documents a low-flow condition (approximately 4,200 cfs) during the Spring Disturbance Flow below Glen Canyon Dam. Data collection and processing techniques were built upon methodology being researched by the USGS Surface Velocity Workgroup and the USGS Hydrologic Remote Sensing Branch.
