The results suggested that water quality of the canal towards closed Oil Jetty was highly deteriorated due to stagnant pond condition and discharges from a refinery. A scenario assessment was also carried by increasing the flows from various sources to understand the site-specific relationships between pollution sources and water quality conditions and also to calculate the assimilative capacity of Hoogly with respect to waste discharged from the industrial units at Haldia. Modelling was never attempted in this region because it was generally felt that simulating such a complex system would not be easy with limited data availability but MIKE 21, a hydrodynamic and water quality model, was used to simulate BOD and DO profiles in the study area and simulation provided reasonably good predictions. This study aims at analysing the impact of wastewater load of industrial units in Haldia on the water quality of the Hoogly estuary using numerical modelling techniques.
