Hi list!
In the documentation of r.watershed (grass 6.4) I found that it's
possible to use the following (optional) input map:
flow
Input map: amount of overland flow per cell. This map indicates the
amount of overland flow units that each cell will contribute to the
watershed basin model. Overland flow units represent the amount of
overland flow each cell contributes to surface flow. If omitted, a value
of one (1) is assumed. The algorithm is D8 flow accumulation.
How is it possible to obtain this map, starting from a DEM?
Thank you
