Abstract
The Qiantang Estuary is characterized by strong tidal bore, high sediment concentration, severe erosion/deposition and frequent human activities. The law of saltwater intrusion is different from other general tidal estuary. This chapter reveals the law of interaction among runoff, channel volume and salinity by means of the analysis of the long-term hydrological and measured salinity data of the Qiantang Estuary. Based on the concept of water, sand and salt mixture density, the muddy water control equations have been derived, and the mathematical model coupling with strong tidal bore-sediment-salinity has been developed as a result, and the model has also been verified, which shows that the result adopting movable-bed numerical simulation model in calculation agrees more with the actual condition.
