Abstract

[automatically translated] In the present work it is evaluated the potential to couple the USLE with the soil water content pre-event or the estimated outflow, to improve the accuracy of the estimate of soil loss at the single erosive event scale. For this purpose, they used two approaches for which the loss of soil and the erosivity factor are related by a power law. The first is the USLE-MM model estimated runoff from a runoff inflows model, SCRRM, importing water content data. The second approach is that of SM4E model that utilizes the water content of pre-event data to correct the erosivity factor of the rain. The two models were tested using the measurements made on land of 22 m made to the experimental stations of Masses and Sparacia. The results show that the USLE-MM, which employs discharge measurements, it leads to better estimates of soil loss. In place, the simulation of the flow or use of soil water content leads to a model of the worst performances of the one found with the original USLE. Further investigations should be carried out to improve prediction of runoff in the plot scale, also by turning to a more extensive measures database.
