Abstract

In this paper, rainfall erosivity based on different time intervals was evaluated for the Penedès region in Barcelona province, an area affected by high erosion processes. Rainfall erosivity was estimated from hourly data (1997–2013), recorded at 4 observatories, and daily data (1960–2013) recorded at 2 observatories of the study area. Spatial and temporal variabilities were evaluated for the analysed periods, considering annual and monthly rainfall erosivities, the number of erosive events and its distribution within the year, the maximum event erosivity and the maximum precipitation event. Annual rainfall erosivity in the study area presented a high degree of variability from year to year. A change in rainfall erosivity within the year was observed, with an increase in spring rainfall erosivity. In autumn, the number of erosive events decreased in September, but the individual event erosivity increased reaching very high values
