Stream and Catchment Delineation in QGIS 3 using GRASS tools

This video shows how to delineate streams and a catchment using the GRASS tools from the QGIS processing toolbox. In another video the same was demonstrated using the SAGA tools in QGIS (https://youtu.be/Ro-RRzMMw-c). At the end of this video both methods are compared.
