Abstract

Water is essential part of human and ecology on earth. The quantity and quality of water now a days a very serious problem in many region especially in industrial and .mining area of India. Since ecology of river depends upon the quantity of dissolved oxygen in the water and due to disposal of waste produced in river Subarnarekha, organic pollution increase and disturbed ecological balance. Here we make a steady state model which is a pair of coupled reaction diffusion advection equation of pollution and dissolved oxygen concentration. Such a model and its solution will aid on a decision support restriction to be imposed on forming an urban practices and simulation enable scenario to be tested for fish survival which is usually taken as above 30% of the saturated dissolved oxygen concentration.
