Supplementary data and software for "Robust surface velocimetry in challenging environments using Image Wave Velocimetry Estimation (IWaVE)"

Supplementary data and codes for article Dolcetti G., Winsemius, H., and Peña-Haro, S., "Robust surface velocimetry in challenging environments using Image Wave Velocimetry Estimation (IWaVE)", submitted to Hydrology and Earth System Sciences: This dataset includes: source videos B1, B2, R1, S1, S2, S3; python recipes for estimating surface velocity distribution with PYORC and IWaVE; estimated surface velocity distributions with PYORC, IWaVE, and STIV; ground-truth ADCP data. The data refer to four measurement sites: Breskens (Zeeland, The Netherlands) - B1, B2; Rhine River (Germany/France) - R1; Sarca River (Trentino-South Tyrol, Italy) - S1, S2, S3.
