Legleiter, C.J., and Kinzel, P.J., 2021, Helicopter-based videos and field measurements of flow depth and velocity from the Tanana River, Alaska, acquired on July 24, 2019: U.S. Geological Survey data release, https://doi.org/10.5066/P9A7J0AN.

Summary

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 per second while [...]

Purpose

The purpose of this study was to assess the feasibility of estimating surface flow velocities and water depths from optical image sequences acquired from a helicopter hovering above the river by tracking water surface features via PIV and inferring depths via a flow resistance equation. Along with field measurements of flow velocity and water depth used for accuracy assessment, these data were used to assess the potential to estimate surface flow velocities and water depths in sediment-laden rivers from helicopter-based videos using particle image velocimetry (PIV) techniques and flow resistance equations. Remote sensing of flow velocities and depths could provide a more efficient, cost-effective alternative to conventional field-based methods of measuring channel hydraulics and thus become an important component of non-contact approaches to streamgaging.
