Mohamed, Maketab and Tengku Yahya, T. F. and Tang, H.S. (2004) Water quality modeling and flow augmentation - Sg Merlimau case study. In: International Conference on Water & Wastewater 2004, 30-31 March 2004, The Mines International Exhibition and Convention Centre, Kuala Lumpur . (Submitted)



Sg. Merlimau study is a cooperative program called Partnership in River Enhancement Program to implement a river rehabilitation program that would improve the water quality of small watersheds with relatively minimal cost and time. High pollutant loads during the low flow period during the dry season was the main cause of water quality deterioration of Merlimau River. The low flow condition was exacerbated by the presence of a dam controlled by an oil palm plantation upstream. The water quality model, QUAL2E was used to model the river water quality and to predict the wasteload allocation and flow augmentation needed to improve river water quality of Sg. Merlimau. Results from the modeling indicated the need to decrease the pollution loads from the major sources of pollution even though the effluents discharged were complying with the environmental regulations. The flow augmentation of about 0.2 m3/s is need from the reservoir above the dam to allow for the dissolved oxygen downstream to be increased to 3 mg/L.
