    Hello.. Thank you for the video.Iit is so useful.I have a questions regarding of delineating the catchtment. Inside the catchment i want to derive several subcatchments. Is it possible? For example in arcmap we can insert several pourpoints and after that we can delineate the subcatchment for those pourpoints. I want to do it in qgis but i cant figure out how to do. I tried to add a shape file With multipoints and adding the pourpoints in the strahler order and use the upslope area but it requires the coordinates for only one point. Also tried to run as a batch process, where i added the coordinates, but is doesnt worked. Please can you help me how to operate? Thank you!

    Thanks for this important tutorial but on installing OSM do you need internet to zoom in? Anytime zoom in the OSM disappears and the DEM will not overlay on the OSM.
    What is the reason?

      Yea it need internet to load map, even internet is not connected DEM should overlay at correct location, you need to check projection system of DEM and Map is same
