Based on this excerpt from the manual, it seems the main external/perimeter watershed boundary, as well as the internal ridges need inputted? "The raster map layer depicting ridges should include the ridge which defines the perimeter of the watershed. The coded stream network can be generated as part of the r.watershed program, but the map layer of ridges will need to be created by hand"
My question is really about the need to manually digitize ridges inside the watershed boundary delineated by r.watershed. As opposed to running r.watershed with a smaller threshold to get these smaller basin delineations within a given study area. If one has to manually digitize the internal ridges in a watershed, I wondered what the point of the module was. It obviously has application, but it seems I am missing something obvious. Hope that is more clear.
