The water erosion potential is calculated using the Revised Universal Soil Loss Equation (RUSLE. It is based on the rainfall erosivity (R), soil erodibility (K), slope steepness (S), and tolerable soil loss (T) is calculated as R*K*S / T where T is the tolerable soil loss. The water erosion potential assumes that there is no cover and no management practices and is base on in the instrinsic properties of the soil and the local climate and topography.
