KBS-RWQ show how best to classify rivers and embark on necessary strategic decisions. Load duration curve has been identified as one of the assessment tool that offers a practical approach to watershed management. The assessment of water quality was based on pollutant loading model establishing the load capacity of the river to determine specific limit for the river in receiving pollutant. The case study demonstrates the system capability in assessment of water quality using LC, important assessment in analyzing individual parameter to the receiving capacity of the river based on...
