[GRASS-user] how to only fill small sinks with r.fill.dir

[Bryan Keith]

Hello,

Is there a way to only fill sinks in a DEM if they are smaller than a
certain tolerance?  I have a couple areas of internal drainage that
really are correct (and quite large), and I have a quite few small
sinks that are incorrect and artifacts of the interpolation.  Any
ideas how to this?  r.fill.dir attempt to fill all the sinks.

I'm trying to improve the results from r.flow  Too many tracks end in
small holes where I'd like them to continue downstream.  Thanks.
