This data set contains supplementary material and the raw data for the Esurf paper Weisscher et al (2020). The supplementary material includes four supplementary figures to the paper and a movie for visual comparison between measured and modelled flow. In addition, there is a supplementary manual that explains how to remodel the hydrodynamics of scale experiments (i.e., the iRIC manual). The raw data of the meandering and braided river scale experiments was collected by Van Dijk et al (2013a). The raw data include for each river type both a DEM file (CSV format) and a .mat data file for that contains the measured and analysed data as presented in Van Dijk et al (2013a). Consult the iRIC manual on how to use the CSV files to remodel the resu...
