The potential risks of hydric erosion are determined using the USLE in a pilot area in the olive grove of the south of Spain. The analysis of the different parameters in the area allows to give constant values for the factors R, C and P. The value K shows a gradient between 0,1 and 0,55, depending on the texture and nature of the clays. The topographical factor (LS) is essential to define the different erosion classes. The results are based on the field observations and the histograms of the thematic maps elaborated using the GIS IDRISI.
