Krishna River is the fourth-biggest river in terms of water inflows and river basin area in India. It has been polluted with agricultural, industrial and domestic pollutants. Since the Krishna river stream is polluted as a result of urbanization and industrialization, its biochemical oxygen demand (BOD) concentration is increasing gradually and other quality parameters also violating the standards. It is necessary to use a versatile water quality model to assess the BOD concentration and other quality parameters and make policies for pollution control. In the current study, the QUAL2Kw model has been applied to evaluate the spatial distribution of water quality parameters Dissolved oxygen and NO3-N in a reach of Krishna river. QUAL2Kw is calibrated and validated using the actual field measurements. This study demonstrated the usefulness of the QUAL2Kw model as a tool to validate critical water quality parameters
