The study compared different models used to predict soil erosion from bare fallow areas during rainfall events. The USLE-M, RUSLE2, and WEPP models were tested using data from erosion events on four plots at different locations. The USLE-M, which calculates soil loss based on runoff, storm energy, and rainfall intensity, provided the most accurate estimates. RUSLE2 also performed well, while WEPP produced the least accurate results. Overall, the USLE-M was the most effective model for predicting event soil loss from bare fallow areas.
