The ultrabasic soils exhibit sources of natural geogenic contamination and potential to contaminate soil and water resources. In Ranau basin area, Malaysia, there are three sub-basins which locate adjacent to the ultrabasic soil. The transport of metals concentration can be assessed using the riverine heavy metal flux analysis based on the empirical erosion models. The erosion models such as the Revised Universal Soil Loss Equation (RUSLE) give a common and extensive framework for evaluating soil erosion and its causative factors. RUSLE examined rainfall (R), topography (LS), soil erodibility (K), cover management (C), and support practice (P) as prominent factors influencing soil erosion. Several heavy metals (Co, Cr, Ni, Pb, Cu, and Zn) and a toxic element (As) were analyzed in this study using the standard laboratory analysis.
