Abstract

This study aimed to evaluate the performance of a simple empirical model (Morgan, Morgan and Finney model, MMF) in predicting spatial patterns of erosion at 2 small catchments in the East African Highlands : Kwalei (Tanzania) and Gikuuri (Kenya). Erosion maps predicted by the MMF model were compared with erosion maps obtained by direct survey. The spatial pattern of erosion predicted by the MMF model was driven by the accumulation of surface runoff, which did not consider the possibility of re-infiltration along the slope. The model predictions could be improved by introducing a more realistic hydrological component for the prediction of surface runoff along the hillslope
