Hi Steeve,

I did apply GRASS in order to generate data for surface runoff and
soil erosion computer simulations (WEPP). This worked just
perfectly as several commands within GRASS such as r.watershed,
r.aspect, ... are very usefull to analyse watersheds and get
information on surface runoff. I also know that GRASS has been
integrated with several of the many runoff and erosion models such as
AGNPS, ANSWRS, Topmodel,... they are all very recomendable!

I though do have no experience in the application of GRASS conserning
subsurface runoff, I am sorry.

Please contact me directly for detailed questions!

Merry X-mas and a happy new one!

regards, Bernd
