Estimation of the Rate of Soil Erosion in the Tasik Chini Catchment, Malaysia using the RUSLE Model Integrated with the GIS

The Tasik Chini Catchment, located at the southeast region of Pahang, Malaysia is experiencing soil erosion problems which are of environmental concern. So a study was conducted that involved the integration of the Revised Universal Soil Loss Equation (RUSLE) with the Geographic Information System (...
