2012). The soil loss rate by water ranges from 16 to over 300Mgha 1 yr 1 in Ethiopia, mainly depending on the degree of slope gradient, intensity and type of land cover and nature of rainfall intensities (Tamrie, 1995; Tesfaye et al., 2014). Studies made in 5 di erent parts of Ethiopia also reported that annual soil loss show spatial and temporal variations.
