【Abstract】 Hangzhou Bay of Zhejiang, including Qiantang River mouth, is a major megatidal estuary in middle coastal waters of China. In its natural environments such unique features and particularities as a typical funnel shape, giant submarine sand bars, a strong hydrodynamic regime, coarsend sediments, and a weakness in resistance to erosion result from the influences and controls by the Changjiang River, Qiantang River and offshore waters. The bay is extremely rich in untapped natural resources such as those available for land reclamation, harbors and navigation channels, fresh water supply, aquatic products, tourism, tidal energy development, etc. However, at present only land reclamation and harbor and navigation channel construction have been planed. The tapping of other resources, with the tidal energy in particular, could be hardly realized in near future due to unconventionally large project scale, tremendous amount of investiment and complexity of factors involved.更多还原
