Description :
This study examines the role of different soil surface features and their influence on runoff formation and on soil erosion in an area seriously affected by overgrazing. Two main surface features were identified and hydraulically characterised, namely : 1) crusted surfaces with embedded gravel widespread on gentle slopes which induce high runoff and erosion rates; and 2) stony surfaces, where freepebbles and blocks protect the top soil against raindrops and overland flow kinetic energy and lead to reduce runoff and soil losses.
