Abstract
An index-approach to catchment-scale soil erosion modelling in six catchments in Cyprus is presented. Within a geographic information system, the four factors commonly accepted to control soil erosion processes are investigated: climate erosivity, soil erodibility, land cover and topography. The factors are combined in a compound index describing the spatial distribution of erosion susceptibility. Sensitivity to spatial resolution and quantitative errors is analysed, and the potential reservoir sedimentation is estimated via a delivery ratio.
