Hi.

I was reading the manual of CASC2D and found it rather interesting.
However I noticed that it's setup is rather complicated. Has anyone
experienced with this model for the modelling of water balance equation
in Grass?

Being this my first approach in watershed modelling I was thinking I
would rather try using a more simpler approach, especially in
consideration of the fact that I have rather scarce data, only temp. e
rainfall of the meteo stations.

I was thinking I would try to obtain a temp map with s.surf.rst and a
rainfall map with the same program. Then maybe, use r.mapcalc for
obtaining an watershed runoff map by subtracting it from the other (I
have an infiltration map).

Any considerations?

Thanks
