Abstract

Empirical models specially event-based versions for estimating erosion are site specific, so calibration is essential for designing soil conservation practices measures. In this study, the efficiency of Universal soil Loss Equation and other event-based versions include USLEM, MUSLE-S and AUSLE evaluated in semi-arid region of khorasan Razavi. Because of small plot size (20 m2 area with annual shrubs cover), The amount of estimated soil loss equaled with measured sediment. Result showed that in addition to overestimation of USLEM and MUSLE-S, models showed temporal variation of sediment significantly. With respect to high and negative values of RMSE and ME of Nash-Shatklyf, models have no significant efficiency. Also, because of the same model structure of AUSLE and USLE models, thay have not significantly efficiency.
