Satellite video remote sensing for estimation of river discharge - Research Data

This repository contains data used to estimate river discharge from a satellite video of the Darling River at Tilpa (Murray-Darling basin, Australia) during a flood event. It includes satellite video footage (acquired 5 February 2022, 23:12 UTC) of the flood, and data and results from HEC-RAS 2D hydraulic model simulations of the flood. Velocities from the satellite video footage were extracted using the PIVLab algorithm, available on the Mathworks File Exchange Service (http://pivlab.blogspot.com/). PIVLab masks and images used in the analysis conducted in the paper are included in this data repository.
