Inherent relationship of the USLE, RUSLE topographic factor algorithms and its impact on soil erosion modelling
Original language description
The accurate representation of the Earth s surface plays a vital role in soil erosion modelling. Topography is parameterized in the Universal Soil Loss Equation (USLE) and Revised USLE (RUSLE) by the topographic (LS) factor. For slope gradients less than 20 percent, soil loss values are similar for both models, but when the gradient is increased, RUSLE estimates are only half of those of USLE. The study aims to assess the validity of this statement for complex hillslope profiles. To that end, both models were applied at eight diverse mountainous subwatersheds. The USLE and RUSLE indices were estimated utilizing the SEAGIS model and a European dataset, respectively. LS factors were in a 3 to 1 ratio (i.e. USLE to RUSLE) considering the entire basin area. For areas with slopes less than 20 percent, gross erosion estimates of both models converged. Sites of strong relief (greater than 20 percent) USLE yielded significantly higher values than RUSLE.
