Análisis espacial de las tendencias de la agresividad erosiva de la lluvia en la Comunidad Valenciana

A Cramer von-Mises test modification is used to detect spatial patterns of rainfall trend signs. Test is performed under two ways. In the first approach, unidimensional model, the clasification criterion selected has been rainfall isoyet. For convenience, this criterion can be modified by using differents index such as erosion, fire risk and so on. In the second approach, the bidimensional model, classification criteria have been latitude and longitude coordinate system, and have been applied to PCI rainfall erosivity index (Oliver 1980). The results obtained by appliying test to a selected meteorological station in Valencia Region let us to define with great detail areas with uniform rainfall trend and uniform rainfall erosivity trends between 1961-1990 normal period.
