Tutorial: Delineate Multiple Subcatchments

1. Introduction

In another tutorial you've learned how to delineate a catchment of a specific outlet. Sometimes, however, you want to do this for multiple outlets or for all subcatchments in a catchment.

After this tutorial you'll be able to:

  • Snap digitized pour points to a delineated river
  • Delineate the catchments of snapped pour points
  • Create pour points for all subcatchments in a catchment
  • Delineate all subcatchments in a catchment
The data provided with this tutorial contains a GeoPackage with a filled DEM, catchment boundary layer and hydrography.

Please note that this tutorial only works with the QGIS 3.10 LTR version and not (yet) with 3.14.
