Acoustic Doppler Current Profiler (ADCP) field measurements of flow velocity from the Tanana and Nenana Rivers, Alaska, collected on August 18, 2021

Field measurements of depth-averaged flow velocity were acquired from the Tanana and Nenana Rivers near Nenana, Alaska, August 18, 2021, to support research on estimating surface flow velocities from remotely sensed data via particle image velocimetry (PIV). The 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. These data were collected along 7 cross-sections on the Tanana River and 7 cross-sections on the Nenana River; two passes across the channel were made at each cross-section. This data release provides depth-averaged flow velocities derived from the raw ADCP data using the TRDI WinRiver...

Acoustic Doppler Current Profiler (ADCP) field measurements of flow depth and velocity from the Tanana River, Alaska, collected on August 18, 2021

Field measurements of depth-averaged flow velocity and water depth were acquired from the Tanana River near Nenana, Alaska, August 18, 2021, to support research on estimating surface flow velocities and water depths from remotely sensed data. 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. These data were collected along 8 cross-sections on the Tanana River; two passes across the channel were made at each cross-section. This data release provides depth-averaged flow velocities and total flow depths derived from the raw ADCP data using the TRDI WinRiver II processing software....

Digital orthophotos of the Tanana and Nenana Rivers, Alaska, acquired from a fixed-wing aircraft on August 19, 2021

This child data release provides the information needed to download from the USGS EarthExplorer portal digital orthophotos acquired along the Tanana and Nenana Rivers near Nenana, Alaska, on August 19, 2021. The primary goal of this study was to assess the feasibility of estimating surface flow velocities from optical image sequences acquired from a fixed-wing aircraft flying along the river by tracking water surface features via particle image velocimetry (PIV). Remote sensing of flow velocities 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. Moreover,...
