This study focuses on assessing the predictive accuracy of soil and nutrient loss models within the Lake Chini Watershed in Pahang, Malaysia. Soil erosion and nutrient loss can have detrimental impacts on water quality, agricultural productivity, and ecosystem health. To address these concerns, various predictive models have been developed. However, their performance in the specific context of the Lake Chini Watershed remains largely unexplored. This research entails the collection of field data on soil erosion and nutrient loss, which will be used to validate existing models and refine their predictions for this unique watershed. The study aims to enhance our understanding of soil and nutrient dynamics, ultimately contributing to more effective watershed management practices.
