Dear Grassers,

I want to define the catchment boundary using Grass4.1. I've used r.watershed program in Grass but
I still have a problrm at the catchment outlet where the terrain is mainly flat which results in a
boundary which is not well defined at the downstream flat end of the watershed. However, r.water.outlet
sounds promising in this case but I couldn't find it in Grass raster programs. I want to define 
the outlet of the basin to give a more realistic unique boundary.

Please, if anyone can help me.....

Thanks,
