AnnAGNPS - Continuous Simulation Model Processes

overview
The AnnAGNPS Pollutant Loading Model predicts (1) water; (2) sediment by particle size class & source of
erosion; and (3) chemicals-nitrogen, phosphorus, organic carbon, & pesticides. These "loadings" are generated
from land areas (called AGNPS cells) and routed through stream systems on a daily basis. Special land use
components such as feedlots, gullies, field ponds, and point sources are included. Details about the
specific processes modeled are given below:
