Abstract

The results are presented of an intensive monitoring programme to determine eroded volumes due to observed rainfall events on a hillslope surface. The surface investigated has been reproduced through a digital elevation model and analysed in terms of drainage network, contributing area and slope by performing planimetric and altimetric analysis. Erosion maps were derived from a comparison of consecutive digital elevation models relative to time. These maps reveal the spatial and temporal evolution of the erosion process at the hillslope scale. The erosion was uniform across the surface, supporting the assumption of randomness in the erosion process commonly used in surface drainage development models. The observed value of erosion has been estimated at approximately 0·11 m/m2 per year with almost 500 mm of total annual rainfall.
