Abstract

This study investigates the spatial and temporal patterns, causes and consequences of landslides in the Gilgel Gibe catchment in SW Ethiopia, and assesses the contribution of the landslides to the high sediment load in the rivers of the Gilgel Gibe catchment. In total, 60 landslides were mapped. High annual rainfall, lithology and steep slopes are preconditions for the landslides. Distance to rivers is significantly the most important precondition, as slopes near rivers are less stable than slopes further away from the rivers. Deforestation caused higher runoff and hence more landslides along the rivers. Heavy rainfall is the main triggering factor
