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

Field measurements of flow depth and depth-averaged velocity were acquired from a reach of the Tanana River near Nenana, Alaska, July 24, 2019, to support research on estimating surface flow velocities and water depths from remotely sensed data via particle image velocimetry (PIV) and flow resistance equations, respectively. The depth and velocity measurements included in this data release were obtained using a TRDI RiverRay acoustic Doppler current profiler (ADCP) deployed from a boat with an outboard motor. This data release provides depths and depth-averaged flow velocities derived from the raw ADCP data using the TRDI WinRiver II processing software. The WinRiver II output was then imported into the USGS Velocity Mapping Toolbox [...]

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. 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. This field-based data set was used to assess the accuracy of remotely sensed estimates of surface flow velocity and water depth derived from helicopter-based videos via PIV and flow resistance equations, respectively.
