The USLE scheme cannot be used at the Sparacia experimental area (near Palermo,Sicily) to predict event soil loss per unit plot area, Ae, because experimental data suggest that, generally, Ae does not increase with plot length, λ. The USLE-MM scheme uses the runoff coefficient, QR, as an additional independent variable in order to develop an empirical model allowing prediction of storm soil loss values that do not necessarily increase with λ. This model allows Ae predictions that both increase and decrease with plot length. Improving runoff coefficient prediction at the field scale is desirable
