A Study Case on Estimation of Soil Loss and Sediment Yield in Curtin University, Malaysia

Because of human activities, soil erosion has been one the most concerning issues in Malaysia past decades. This study aimed to estimate amount loss and sediment yield at Curtin University, by using Revised Universal Soil Loss Equation (RUSLE) Modified (MUSLE), respectively. The parameters RUSLE include rainfall erosivity factor (R), erodibility (K), slope length (L), steepness (S), cover-management (C) support practice (P). data (10 years) from Sarawak Meteorological Department was used determine R-factor. K-factor determined sieve analysis, hydrometer Standard Proctor Test (SPT), organic content testing. L-and S-factors were performed measuring on site Google Earth. C-and P-factors based ground surface cover condition (bare this study). In MUSLE, runoff comprises V Qp, while other are same as RUSLE. depth, V, is equivalent intensity. Rainfall intensities recorded a rain gauge. highest intensity for depth. Rational method utilized calculate Qp. estimated 119.97 tons/ha/year 0.76 ton/storm event Malaysia.
