Thank you very much for the suggestion! I will try that after selecting the subbasin that contains at least one of my points.<br><br>Dafne<br><br><div class="gmail_quote">On 12 August 2010 17:51, Rich Shepard <span dir="ltr"><<a href="mailto:rshepard@appl-ecosys.com">rshepard@appl-ecosys.com</a>></span> wrote:<br>

I used r.watershed to get the streams channels and now I am looking for an<br>
automatic way to dismiss the part of the network above the points of<br>
interest for my application.<br>
<br>
Is that any tool to do that with GRASS?<br>

Yup. Make a mask (see r.mask) and use that to either select the subbasin<br>
you want or to remove the portion you don't want.<br>
