Rural Non-Point Source Pollution Models?

[Nandish Mattikalli]

Hi,

Are there any models (capable of predicting non-point source
loadings, and their transportation in RURAL watersheds) that have
been integrated with GRASS? I am looking for models that can handle
effects of land-use/ land-cover change, and agricultural
intensification etc. on surface and ground water quality.

I appreciate any help.
