Hi Jeremy, 
one application to GRASS is the AGNPS-Modell. The AGricuktural Non-Point
Source is a distributed parameter model. It predicts soil erosion and 
nutrient transport/loading from agricultural watersheds for real or
hypothetical storms i.e., it's an event-based model.
In WWW you will find all about AGNPS at the following page:	

		http://soils.ecn.purdue.edu/~aggrass/agnps/


You will find further information about a "GRASS Program for Determining
the Topology of Stream Networks" (r.watershed, r.tribs) at:

Hope this will help you.
