Hi All,

I´m beginner in Grass and need work with hydrological Analysis. Is it possible define a watershed from one point (x,y) like ArcHidro Extension? I didn´t find this tool in Grass.

Thanks in advance and sorry for my bad English.

See

http://grass.osgeo.org/wiki/Hydrological_Sciences#Watershed_modules
-> r.water.outlet: Generates a watershed basin from a drainage direction map
    (from r.watershed) and a set of coordinates representing the outlet point
   of watershed.

I hope this is what you look for.
