Abstract

Evaluation of soil erosion by existing models is required as an important tool for appropriate water and soil conservation purposes. The present study aimed to assess the applicability of Hill slope Erosion Model (HEM) as one of the newest erosion models for prediction of storm-wise sediment yield. This study was conducted in Khosbijan rangeland with 9, 15, 20 and 25 percent slope steepness by using soil erosion standard plots. Runoff depth, vegetation cover density, land surface cover, soil texture, slope steepness and length were determined for 16 storm events. The results showed that the uncalibrated HEM didn’t simulate the observed sediment yields, properly. Calibration of soil erodibility parameter and developing regression between observed and estimated data indicated that the model could not predict sediment yield in plots with 9 and 15 percent slope steepnesses with determination coefficient of less than 0.4 (p≤0.135). The model could successfully predict the soil erosion rate in plots with 20 and 25 percent slope steepnesses by applying soil erodibility parameter of 0.8 with determination coefficient of 0.355,0.803 and estimate error of 56 and 35 percent, respectively.
