Estimating the Best Exponent and the Best Combination of the Exponent and Topographic Factor of the Modified Universal Soil Loss Equation under the Hydro-Climatic Conditions of Ethiopia

The effect of the topographic factor Modified Universal Soil Equation (MUSLE) on soil erosion and sediment yield is not clear. Except for coefficient, erodibility, cover, conservation practice factors MUSLE, an individual exponents MUSLE can be seen by applying model at different watersheds. A primary objective this paper to estimate best under hydro-climatic conditions Ethiopia. For sake calibration procedure, main that directly affect process, such as practice, factors, are estimated based past experiences from literature comparative approaches, whereas parameters do process or have no direct physical meaning (i.e., coefficient a exponent b) through calibration. We verified 1 irrespective factor, which results in maximum performance approximately 100%). corresponds equation 0.57; case, greater than equal 80% all watersheds our consideration. expect same other Ethiopia, while decreases. Therefore, original changed 0.56 0.57, equations provided paper.
