Hi dear GRASS users,

I´m writing my diplom thesis in Freiburg Germany. I have a
high accuracy DEM (res=0.5m). There are a lot of small
(2-20m diameter, up to 30m deep) deprssions/holes (almost
spherical) in the DEM. I would like to classify them with
the watershed algothm. But the basins don´t fit to the real
deprssions. There are too many basins in one hole and
sometimes there is one basin but two holes... 

Any ideas? Do I have to change the settings? Is there a
better algorithm?

Thank you,
Johannes
