Summary

This data release includes digital orthophotos acquired from a fixed-wing aircraft and field measurements of flow velocity from the Tanana and Nenana Rivers near Nenana, Alaska, obtained on August 18 and 19, 2021. This parent data release includes links to child pages for two data sets produced during the study: 1. Acoustic Doppler Current Profiler (ADCP) field measurements of flow velocity from the Tanana and Nenana Rivers, Alaska, collected on August 18, 2021. 2. Digital orthophotos of the Tanana and Nenana Rivers, Alaska, acquired from a fixed-wing aircraft on August 19, 2021. Please refer to the individual child pages for further detail about each data set. Overall, these data were used to assess the potential to estimate [...]

Purpose

The purpose 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, the ability to collect such data from a moving aircraft opens up the possibility of examining longer river reaches via remote sensing.
