   There are several hydrologic modules available for your use. The raster
manual (r.*) has details on each, and the wiki has a section on hydrological
modeling.

   The question you need to answer in order to get more focused help here is
just what it is you want to do. What problem are you trying to solve? What
behavior(s) do you want to explore? Specificity, and telling us what you've
done so far to educate yourself, goes a long way to helping you.
