[GRASS-user] river network modelling

[Hamish]

ISTR that the streams and the subbasins share the same category number,
which should make selecting out the subbasin quite easy.

Thank you very much for the suggestion! I will try that after selecting the subbasin that contains at least one of my points.

I used r.watershed to get the streams channels and now I am looking for an

interest for my application.



Is that any tool to do that with GRASS?




Dafne,



  Yup. Make a mask (see r.mask) and use that to either select the subbasin

you want or to remove the portion you don't want.
