对威海九龙湾海域进行二维水动力-谱波和水动力-水质的耦合计算?分析,研究堤防建设工程前后潮流场、波浪场的变化,并对工程导致的水质变化进行数值计算、分析。潮流场的数值计算结果与实测潮位、流速、流向值进行对比,验证了该模型的准确性。计算结果表明,工程建设对海域潮流场的影响主要集中在距工程位置1.3km范围以内海域;工程建设改变了周边的波浪传播方向,使得掩护范围内的水域的波浪作用明显减弱,有利于后方岸滩的保护;施工期所产生悬浮泥沙对海洋环境的影响主要位于施工区1km范围内,其范围以外海域受到的影响不大。
The calculation and analysis of two-dimensional hydrodynamic-spectral wave and hydrodynamic-water quality in the waters of Kowloon Bay in Weihai are carried out to study the changes of tidal current and wave field before and after the embankment construction project, and the numerical calculation and analysis of the water quality changes caused by the project are carried out. The numerical results of tidal flow field are compared with the measured tidal level, velocity and flow direction to verify the accuracy of the model. The calculation results show that the influence of engineering construction on the tide field in the sea area mainly lies in the sea area within 1.3km away from the project location. The project construction changes the direction of wave propagation in the periphery, making the wave action in the waters within the scope of protection significantly weakened, The protection of the beach; the suspended sediment produced during the construction period has an impact on the marine environment mainly within 1km of the construction area, and the impact on the sea area outside the scope is not significant.
