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

This paper presents the results of rill experiments accomplished in Andalusia (at Negratin, Freila, Salada and Belerda) in September 2008 using a novel experimental set up. Rill cross sections, slope values, flow velocities and sediment
concentrations were measured and these values were used to calculate sediment detachment and transport. In rill experiments, 4 different natural rills were flooded with the same experimental setup. Several processes like transport of loose material, erosion, bank
