Abstract: The River Mahananda, which runs past Siliguri City,WB, is at present one of the most polluted rivers in North Bengal. Presently Siliguri is a very densely populated and will be one of the important cosmopolitan cities of West Bengal. However, only a small fraction of the total wastewater being generated in the city is treated. Consequently, the amount of untreated wastes, both domestic and industrial, being released into the Mahananda is tremendous and is increasing day by day. Therefore, the objectives of this study were to investigate the status of the river water quality by using mathematical modeling [1] in terms of some cardinal water quality parameters, and to simulate the dissolved oxygen (DO) level. In order to fulfil the objectives, a comprehensive datas were collected from West Bengal Pollution Control Board (W.B.P.C.B). Then, a one-dimensional water quality model was developed for the Mahananda river system for a dry and monsoon period of last ten years.. In this paper an attempt has been taken to study and simulate the environmental condition along the river by mathematical tools and predict the pollution status.

Keywords: Siliguri City; River Mahananda; pollution; mathematical model; DO, dry season, monsoon season.
