Velocity and Discharge
The child item includes discharge measurements, channel area, surface velocities, and derived discharges using the entropy-based probability concept and four image velocimetry algorithms. The probability concept parameter ϕ (phi_ was computed using field methods and derived from pairs of mean and maximum velocities. The dataset provides a comparison of remote sensing-derived discharges versus discrete acoustic Doppler Current Profiler measurements, highlighting the percent errors and mean absolute differences.
