| 摘 要： | The siltation induced by wind waves in an entrance channel is one of the prime factors influencing the operation efficiency of a port.It is necessary to predict the siltation accurately for dredging and ship operation passing through the entrance of the port.However,it is difficult to apply the traditional method to predicting entrance siltation because of its complex computational procedure and lacking the data of ocean dynamic elements in the specified sea area.From the view of energy conservation,a direct relationship between wind conditions and sediment deposition can be founded.On the basis of the above methodology,an empirical formula expressed by wind conditions for forecasting the siltation in the entrance channel is set up.The wind conditions are easily obtained from the local meteorological stations or weather maps,so the formula established in this paper is more convenient and practical than the traditional method.A case study is provided,in which the emopirical formula is calibrated and verified utilizing the measured wind and siltation conditions in the entrance channel of the port.Comparisons between computed values and measured data show satisfactory agreement. |
