More College , Dhanbad ABSTRACT: The quantity and quality of water now a day a very serious problem in many region especially in industrial and mining area of India. Damodar river basin is repository of 45% of India coal reserve. Exploitation of coal & related industries in the area has exerted a great impact on the water pollution. In this paper an attempt has been made to develop a mathematical model to obtain concentration levels of Damodar river under different dumping policies so as to select the policy which disposes maximum waste without exceeding acceptable limits. An analytical solution is obtained to study the concentration levels of pollution for different time histories in Damodar river. The model can be useful in guiding engineering and management decision concerned with the efficient utilization of Damodar river water & protect their quality.

Latitudes to 24˚31’30”N. Latitude and 84˚41’ 00”E. Longitude to 86 51’45” E. Longitude. The basin starts from high hills of Palamu in Jharkhand to Hooghly in West Bengal and stretches over nearly 18,100 Sq.Km.
