Study on tidal current and sediment mathematical model of Pingyang Port West Bay Operation Area in Aojiang Estuary
摘要
Abstract
Aiming at the Pingyang Port West Bay Operation Area in Aojiang River Estuary,a two-dimensional tidal current and sediment mathematical model considering wave action was established.On the basis of comprehensive verification of the model,the variation law of tidal current movement after the construction of the port project was simulated,and the characteristics of tidal current field and transverse flow at the wharf front were analyzed.The sediment siltation intensity and distribution of the harbor under normal wind and wave conditions were analyzed,providing a scientific basis for the design of Pingyang Port.The results show that the engineering sea area has strong wave and tidal current dynamics,abundant sediment sources,and high sediment concentration under normal wind and wave conditions.After the construction of the port project in the Pingyang Port,the maximum cross-flow at the wharf front would not exceed 0.5 m/s.Under normal wind and wave conditions,the average annual siltation intensity of the harbor is 2.0 m/a,and the maximum annual siltation intensity is about 2.4 m/a.Compared with the previous research results of the trial channel,the siltation rate of the sediment has decreased.关键词
