Key Points
- Satellite video acquired along 12.6 km of the River Darling,
Australia, at 5 Hz for 28 s during a 1-in-5-year storm event.
- Satellite video-based velocity measurements estimate riverine
discharges to within 15% of in situ gauging station
observations.
- Parametrization of non-contact velocimetry and choice of a
depth-averaging coefficient (α ) influence the accuracy of
discharge estimates.
