Abstract

Integrated watershed management is a holistic approach of understanding all the factors affecting the river system. The carrying capacity, point sources and non-point sources loads have to be Measured or estimated and accounted for. The accounting tool for calculating the waste and allocation and the total maximum daily loads (TMDLs) are water quality models. The use of water quality, models in wasteload allocations is not a new concept but their applications in the Malaysian watershed management is. Most water quality models are used for wasteload allocation for the sustainabilitv of the designated river-water quality. To achieve the targeted mater quality certain policy changes and the imperative cooperation of various government departments and agencies including but not restricted to local councils, Department of Irrigation and Drainage (DID). "Ministry of Housing and Local Government, Department of Forestry, Ministry of Agriculture and water companies. The policy changes needed would include the pollution loads limits of point sources. There would be also the need to assess the non point sources pollution of both urban and rural agricultural environment and the necessity of pollution load assessment from the usually, ignored sources such as wet market, hawkers and untreated household sullage. There are many water models available for water quality managers- from the ones available in the public domain for free to the expensive ones where license has to he purchased annually. The water quality model users need to provide certain data such as water quality parameters, stream discharge, river hydrogeometry and pollution sources locations and loads. Water quality simulations from the calibrated model in the long run would help water quality managers to efficiently and effectively manage their respective rivers.
