Longitudinal variation of water quality in Sungai Jarum catchment - linking ecology with hydrology for reservoir management

In recent years, human activities, such as urbanization and agriculture, have been blamed for the degradation of water quality in many developing countries. Rivers draining agricultural land are susceptible to diffused or non-point source pollution. A study was conducted in Timah Tasoh catchment are...
