[GRASSLIST:5168] area/volume depression

Hi Grassusers,
The r.fill.dir and r.mapcalc are a good way to find depressions in a DEM.

The next step is often : how to obtain the following curves :
- volume = V(depth)
- area = A(depth)

Does anybody have such a script or command , or an idea to calculate
these curves ?

Thanks.

You may want to look at the manual pages of
r.volume
r.surf.area
