摘  要:
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。

摘  要:
2-D coupled hydrodynamic-wave model and hydrodynamic-water quality model are established to study the influence of renovation project in Jiulong Bay.Changes of tidal current field and wave field are calculated before and after the project construction,also the influence on water quality is calculated during the project renovate.The tide level and tidal current field are compared with the observed data,with good agreement,proving the accury of the basic hydrodynamic model.The influence on tidal current field in the range of 1.3km away from the project area.The wave direction turns sharply and wave height decreases due to the sheltering of the newly-built dike.The water quality change mainly occurs in the area within 1km from the project.
