Dear GRASS users,
I would like to get the elevation difference between the watershed pixel and its closest related river pixel (box pixels are in the same sub-basin).
The watershed pixels and the river pixels should be in one sub-basin, thus the elevation difference is not be computed based on the river pixel which is closer but in the another sub-basin.
Also does somebody have and algorithm to flood the floodplain in several steps with user defined water levels? I would appreciate any hint here.
Thanks a lot,
Rado

I'm sorry but I don't understand. Maybe if you could explain
it otherwords? Sorry.
