r.basins.fill -
r.basins.fill generates a raster map layer depicting subbasins, based on input raster map layers for the coded stream network (where each channel segment has been "coded" with a unique category value and for the ridges within a given watershed. 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 digitizing using the v.digit program.
