Channel: Hans van der Kwast
Date: 2022-05-10

This video covers section 4.9 of the book QGIS for Hydrological Applications, Second Edition, by Hans van der Kwast and Kurt Menke. You'll learn how to delineate the catchment polygon for an outlet. The catchment is first delineated as a raster using the catchment tool from the PCRaster Tools plugin. Next, the catchment is converted from raster to polygon vector.
