AGNPS is a tool for use in evaluating the effect of management decisions impacting water, sediment and chemical loadings within a watershed system. The term "AGNPS" now refers to the system of modeling components instead of the single event AGNPS, which was discontinued in the mid-1990's. These enhancements have been included to improve the capability of the program and to automate many of the input data preparation steps needed for use with large watershed systems.
