摘要
同安湾鳌园沙滩岸段处于湾顶,该水域潮流、波浪动力较弱。该海域清淤工程会对鳌园沙滩水动力环境及泥沙运动产生影响。本文分析了清淤工程后鳌园沙滩上波浪、潮流动力变化特点,以及在此动力条件下泥沙含沙量变化,分析了鳌园沙滩上不同位置泥沙淤积及泥沙运动。表明清淤整治工程后,鳌园沙滩潮流依旧很弱,波浪动力略有增加,含沙量降低平均为0.025 kg/m^3,沙滩上泥沙淤积量在1.18 cm/a以内,沙滩上沿岸净输沙方向为由东向西,净输沙867 m^3/a。清淤工程利于鳌园沙滩的维持。
Aoyuan Beach is at the top of Tongan Bay, whose power of tidal and wave is weaker. The dredging project will affect the hydrodynamic environment and sediment movement of the beach. The characteristics of wave power and tidal power after the dredging project, sediment concentration changes in this dynamic conditions, and sediment deposition and movement at different locations on Aoyuan Beach were analyzed. The result showed that the tide of Aoyuan Beach was still weak after the dredging project, the wave power increased slightly, sediment concentration reduced 0.025kg/m^3 on average, sediment deposition was within 1.18cm/a, the direction of the net sediment transport was from east to west, and the net sediment transport was 867m^3/a. Therefore, the dredging project was conducive to the maintenance of Aoyuan Beach.
