    Abstract
    Rainfall erosivity is the primary cause of soil erosion establishing an environmental constraint that restricts and conditions land use and soil management. Thus, in the context of the climate change, the understanding of the alteration in rainfall characteristics and their influence on soil erosion is one of the main concerns of soil conservation studies. In this work, the seasonality rainfall index (SI) of Walsh and Lawler, precipitation concentration index (PCI), and modified Fournier index (MFI) for rainfall erosivity have been estimated and analyzed for East Andalusia region. Monthly rainfall data (from 1945 to 2005) of 277 rainfall gauges distributed over the region have been used. The region is characterized by high year-to-year variability in rainfall and a marked irregular distribution of the rainfall over the year and thus monthly rainfall erosivity. The spatial variability of the analyzed indexes is shown in maps. Their temporal data series are also analyzed in order to detect tendencies by using the non-parametric test, based on the range, of Mann-Kendall.
