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.<br>

Hello Francesco,<br>
<br>
you could use something like the AddOn r.stream.basin (<a href="http://grass.osgeo.org/wiki/R.stream.*" target="_blank">http://grass.osgeo.org/wiki/R.stream.*</a>)<br>
to delineate the basins. Every basin gets a unique number. Afterwards you can just query how<br>
many cells do have a certain number.<br>
<br>
best regards!<br>
