Descripción
The Revised Universal Soil Loss Equation (RUSLE) is applied in Spain, as in other countries, to determine the rate of water erosion on agricultural soils as well as to evaluate the efficiency of consequent conservation practices. The rainfall erosivity factor (R-factor) involved in RUSLE equation is based on kinetic energy of falling rain (KE) and maximum 30-min intensity of storms (I30). In particular, the R10 factor represents the erosivity of a storm with a 10 year return period. This value is used to calculate transportation capacity and deposition for concave slopes, vegetatition strips and channels; reduction of erosion by ponding; effectiveness of contouring; and critical slope length for contouring. The aim of this paper is to propose a new method to calculate the R10 factor considering new available data. Our approach uses regionalization methods and the SQRT-ET max function for analysing precipitation distribution. In addition, the relationship between kinetic energy and daily rainfall is obtained. The kinetic energy is estimated with potential equations from daily rain. The results have been processed using GIS and AJAX techniques allowing to design a new software, through which it is possible to obtain the R10 in somewhere of Spain The R10 factor values should be proposed as constitutive standards for the whole country. This change will result in more efficient conservation practices and will lead in future to better protection of soil from erosion
