erosion, Way Khilau Sub-Sub-Watershed, USLE, MUSLE, RUSLE.


Soil erosion and ecological environmental damage cause environmental and resource problems in the Way Khilau Sub-Sub-Watershed. The purpose of the study was to compare the predictions of the soil erosion rates of the universal soil loss equation (USLE), its revised model (RUSLE), and its modified version (MUSLE). This study comprises several stages; literature review, data collection, and erosion calculations. The erosion calculations were based on 3 methods; THE USLE, RUSLE and MUSLE methods, which were then analyzed for the results of the comparison. The largest erosion values of all the methods on steep slope land (25-45%) were 526.5485 tons/Ha/th with the USLE Method, 585.3 tons/Ha/th with the RUSLE Method, and 13202.38 tons/Ha/th with the MUSLE Method. The lowest erosion values of all methods on sloping slope land (0-8%) were 0.879 tons/Ha/th with the USLE Method, 0.94 tons/Ha/th with the RUSLE Method, and 22.04 tons/Ha/th with the MUSLE Method. The results of the calculations of the average erosion per year in the Way Khilau Sub-Sub-Watershed with the USLE and RUSLE methods fall into the medium category (S), while with the MUSLE Method, it falls into the very heavy category (SB). In conclusion, the USLE and RUSLE soil erosion models had relatively similar results, yet the MUSLE model showed a higher spatial difference in erosion potential than the other models.
