On average, a gully density of 1.14 km km −2 was measured in 1935-1936 of which the larger portion (75%) were vegetated, indicating they were not very active. Over 80 years, gully density has significantly increased to 1.59 km km −2 with less vegetation growing in their channel, but 66% of these gullies were treated with check dams.Saunders and Young (1983) in their review of rates of slope erosion indicate downcutting exceeding 1 mm/yr in semi-arid climates, whereas in arid regions the values are on the order of 0.01 mm/yr. In semi-arid zones, in areas composed of easily erodable material, the rates of denudation are arguably the highest in the world.
