Abstract

Through a composite analysis of long-term climatic controls on rain erosivity in the Calore River Basin (northern Campania, southern Italy) for the period 1869-2006, and based on a parsimonious interpretation of rainstorm processes, a model(comparable with the Revised Universal Soil Loss Equation) was adapted to generate erosivity values on different time-aggregation scales (yearly and seasonal). The evolution of the generated series of cumulated and extreme erosivity events was assessed by 2 return period quantiles. The results indicate that soil erosion risk tends to rise as a consequence of an escalation of the climate erosive hazard, predominantly between April and November (associated with cultivation and tillage practices)
