I have a DEM of a river basin and I want to delineate sub-basins for certain points of which I have the coordinates.
Can you suggest an AUTOMATIC method in MATLAB or in GIS to do it?

You can also download HEC-GeoHMS to work in GIS environment and delineate sub basins. It is really good one to delineate sub basins.

Leônidas Luiz Volcato Descovi Filho I have already used that algorithm and after w.watershed.outlet, but it is not an automatic procedure. I also have a problem with the Python code if I send this last algorithm in series.
Thanks a lot for the answer|
