| 摘 要： | I~crIOWIn the coastal area, especially at the sandy seashore, wave and nearshore current are the major factors which affect sediment transPOrt and the motyhChdynamics.The numerical models of predicting the beach evolution can be classified intO the medi~term and long-term models according to their space and time scales (De Briend et al., 1993;Watanabe, 1990; Watanabe et al., 1986; Tao, 1996). In the medium-term model the effects ofwave, nearshore current and sediment transport are conside…

| Abstract: | A systematic study of waves, nearshore currents and sediment transport related to the coastal evolution of sand beach under the action of wave, has been carried out. On the basis of the re sults, a numerical model of sand beach evolution around coastal structures has been established. To pre dict the bed topography, the sediment transport rates of bedload and suspended load under the action of wave and nearshore current as well as the effects of wave on the sediment are considered. The sand beach evolutions caused by a breakwater and a settled ship near the shore are simulated. |
