Hillslope erosion by rainstorms–a magnitude-frequency analysis
Authors:Jan De Ploey  Michael J Kirkby  Frank Ahnert
Abstract:Daily rainfall data for four stations in Europe and east Africa are used to obtain, by means of magnitude-frequency analysis, a measure of the Cumulative Erosion Potential (CEP) that takes into account rainfall characteristics, soil water storage, and granulometric properties of soils. The CEP has the advantage of being calculated from generally available published rainfall data, so that wide regional coverage is possible. Together with additional data on the surface configuration and on seasonal variations of rainfall and plant cover, the CEP can provide a basis for estimating hillslope erosion by overland flow.
Keywords:Soil erosion  Erosion potential  Magnitude-frequency analysis  Wash denudation
