[GRASS-user] upslope contributing areas

[Rainer M Krug]

It depends on what the OP was looking for - it sounds to me that he is
looking for a kind of "dynamic" approach, where one can determine the
upslope drainage area for an arbitrary location. Unfortunately, I don't have
a solution, but would be quite interested in the answer.

Cheers,

Rainer
