The approach of the US working group to the development of a hierarchy of mathematical models dealing with non-point-source pollution at the field level is described. The objective of the group is to use this system of models for assessing non-point-source pollution, quantifying responses from alternative management practices, and evaluating the best ones. Each model should be simple, but physically based. The following phenomena are described consecutively, with discussions of approaches to their modeling: surface and subsurface flow, deep percolation, erosion, sediment transport, and dissolved and adsorbed chemical output due to use of fertilizers and pesticides. The system is not considered to be an end in itself, but a first step towards the development of user-oriented comprehensive models.
