| Description |
An appropriate pollutant species transport model has been applied for the prediction of water quality parameters along the Damodar river stretch. This paper addresses the incorporation of various influencing parameters in water quality dispersion phenomena such as velocity variation over the cross section, variation in river dimension and settleable bio-flocculated particulate parameters. A computer aided model has been developed and applied to compute accurate and rational flow rate as the flow rate is one of the most important parameter for accurate water quality prediction. As most of the existing models assume the river as one dimensional while predicting water qualities, the application of such models in wide rivers can’t return the accurate results, which may not reliable for devising suitable mitigative measures. The river Damodar is considerably wide and many tributaries carry the effluents of different industries such as coal mines, coal washeries, coke plants and townships with various types of pollutants, which have different characteristics in nature to degrade the river ecosystem. The present study has been conducted to simulate water quality along the stretches of Damodar river in Dhanbad district during winter season. The velocity variation over the cross section, changes in river dimension, the impact of river course, and the percentage and the settling velocity of particulate maters duly incorporated in the present model. It has been observed that the model is effective and economic to study the water quality dispersion along the river stretches with 3 to 7% of error compare to the analyzed data. Non-conservative water quality parameters such as Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Biological Oxygen Demand (BOD), Dissolved Oxygen (DO) and Chemical Oxygen Demand (COD) have been predicted in order to study the dispersion phenomena of the river stretch blended with washery effluents. The present study may be useful for decision makers, industrialists and environmentalists to devise suitable Environmental Management Plan and to design appropriate meditative measures
