This data release includes measurements of surface velocity magnitude and direction from the Colorado River at Compact Point near Lees Ferry, AZ, on March 18, 2021. These data were used to develop a remote sensing technique for measuring reach-scale river surface velocity magnitude and direction from overlapping video data. The dataset contains approximately 1.2 km of river length. The purpose of this study was to assess the feasibility mapping surface velocity from overlapping video acquired from a small unmanned aircraft system (sUAS) hovering above the river by applying Large-Scale Particle Image Velocimetry (LSPIV) techniques, and to establish best practices for creating reach-scale surface velocity maps. The...
