The article offers information on the stimulation of phosphorus transport in an agricultural watershed using the water erosion prediction project (WEEP) model. The authors state that the WEEP model has been tested for its ability to predict soil erosion, runoff, and sediment delivery over a wide range of conditions and scales for both hillslopes and watersheds. They explain that the study aims to program, incorporate, and test the ability of WEEP to estimate total phosphorus (TP) loss with sediment at the small watershed scale. They also point out that the study suggests that further developments of the phosphorus model could lead to the incorporation of a nutrient cycling routine in the WEEP model to adjust the amount of phosphorus [...]
