Hello,
I need a grass program that can give me, for any location on an
elevation model, which pixels are contribution to the water flow.
r.watershed is not exactly what I want, because you cannot choose
the point where your watershed ends (I have several mesure and
simulation along a river, and look for contributing area at each
location)
Does anybody have such tool or any other idea ?

Hi, Michel
You'll want to use r.water.outlet in conjunction with a drainage map
generated by r.watershed.
