[GRASS-user] trace channel from accummulation raster

Is there a way to extract a channels from the accumulation raster, e.g.
accumulation from r.watershed?
Somehow r.drain delivers something which is not following the accumulation
raster. In theory the accumulation along the drainage shoult always increase
and never decrease. My results show a nice increasing trend, which is
interrupted with very low values.
Did anybody came across similar problems?
thanks for your help!
