ABSTRACT
In the present paper, it is attempted to carry out computer simulation studies for Kanhan river stretch using MIKE-11 modeling tool to evaluate Assimilative Capacity (AC) based on existing and projected waste load scenarios. AC of Kanhan river was estimated in relation to biochemical oxygen demand (BOD) and dissolved oxygen (DO). MIKE-11 model simulates the DO and BOD parameters in a one dimensional fashion by calibrating with field data different constant and model parameters. The modeling studies would help in deciding the appropriate waste load allocation based on stream's AC rather than simple effluent standards. The model studies will provide vital information and greater insight into the impact of point and non-point sources of pollution on quality of Kanhan river in a stretch of 120 km.
