[GRASS-user] r.watershed identify inland watershed

[Micha Silver]

Hello:

You might try `r.param.scale`, or even better `r.geomorphons` modules to 
identify geomorphology features, then filter out all pixels identified 
as pits.


r.watershed is purposely designed to overcome depressions, and find flow 
routing thru these spots. So I don't think you can use that module to 
identify depressions.
