Does the new catchment delineation method works on small islands (Seychelles as an example) ?

Best regards

I just tried the Seychelles, and could not get the tool to work. However, it does work for the Galapagos Islands in Ecuador. So the threshold is somewhere between those two. All of this depends on the digital elevation data pulled by WEAP to delineate the catchments. The dataset used is HydroSHEDS. More information about HydroSHEDS is available at https://hydrosheds.cr.usgs.gov/datasource.php
