Improving the Modified Universal Soil Loss Equation by Physical Interpretation of Its Factors

A primary objective of this paper is to change the input data requirement Modified Universal Soil Loss Equation (MUSLE) for calculation its runoff factor possible application in data-scarce areas. Basically, MUSLE was developed a small agricultural watershed, where extent erosion from sheet rill erosion, but we cannot exactly tell whether it considers gully or not. The underlying physical assumption improve that amount potential energy proportional shear stress sediment transport slope field and kinetic at bottom formation. improved tested four watersheds Ethiopia, showed better performance (i.e., minimum 84%) over original 80%), all under our consideration. We expect same be true other Ethiopia.
