| 摘 要： | In this paper the characteristics of tidal flow and seasonal variation of seidment content in theHangzhou Bay and their affecting factors are studied.Field investigations and data analysis indicate thatthe sediment movement is mainly influenced by the Yangtze estuary and the sediment of the Yangtze estua-ry is induced by wind wave and tidal flow.Owing to the variation of dynamic conditions,the instanta-neous sediment content is controlled by tidal flow,wind wave,depth of water and tidal range synthetically.A sediment content relationship formula is established with related factors.A non-equilibrium2-dimensional numerical model of suspended sediment transportation is set up,and the finite element meth-od is applied.The computation results of the model is in accordance with field data.

| Abstract: | In this paper the characteristics of tidal flow and seasonal variation of seidment content in the Hangzhou Bay and their affecting factors are studied. Field investigations and data analysis indicate that the sediment movement is mainly influenced by the Yangtze estuary and the sediment of the Yangtze estuary is induced by wind wave and tidal flow. Owing to the variation of dynamic conditions, the instantaneous sediment content is controlled by tidal flow, wind wave, depth of water and tidal range synthetically. A sediment content relationship formula is established with related factors. A non- equilibrium 2-dimensional numerical model of suspended sediment transportation is set up, and the finite element method is applied. The computation results of the model is in accordance with field data. |
