Abstract
ABSTRACT: A model called SPNM from the words “sediment‐phosphorus‐nitrogen model” was developed for simulating agricultural contributions to water pollution. SPNM is designed to predict sediment, P, and N yields for individual storms on small basins and to route these yields through streams and valleys of large basins. Users need no computer programming experience because the model is a problem‐oriented computer language. SPNM is useful in planning water resources projects and in research. Tests of the model on a watershed provided realistic results.
