Abstract
The river restoration scenario analysis was carried out using steady state US-EPA Water Quality Analysis Simulation Program (WASP8) for Hindon River in India which has been classified as Class E by Central Pollution Control Board (CPCB). Restoration scenarios for load reduction, flow augmentation, reaeration and dredging were generated after fairly calibrating and validating the model. The scenario analysis indicated that reductions in municipal waste load and reduction in sediment oxygen demand would significantly improve the water quality along the river. Flow augmentation scenario also seemed to improve the water quality to some extent however it does not fulfil the criteria set by CPCB for the propagation of wildlife and fisheries. However, it may prevent stagnation of water along the river stretch. Therefore, high levels of sewage treatment work are required to strengthen the restoration activities and render the water quality better.
