摘要
在淤泥质海岸建设大型海岸工程,会对周边海域的水沙环境产生一定影响。文章以连云港为例,应用波浪潮流泥沙数学模型,模拟计算了连云港海域大型海岸工程实施后对于水流泥沙运动的影响。研究结果表明:连云港区、徐圩港区以及灌河口双导堤工程实施后,工程区以外的大范围海域潮流场和含沙量场基本没有改变,变化主要集中在工程区和工程区附近近岸海域,总体呈现出动力减弱、含沙量减少的趋势。
Constructing large-scale coastal engineering in muddy coast may influence hydrodynamics and sediment transport in the surrounding sea area to some extent. In this paper, taking Lianyungang Port as an example, a numerical model of wave, tidal current and sediment was used to study the changes of flow current and sediment concentration before and after the construction. The results show that： after the projects of Lianyungang Port, Xuwei Port and the regulation of the Guanhe estuary, tidal current field and sediment concentration field are not changed outside the project region, while the changes appear in the engineering water area and the surrounding near-shore region. The hydrodynamics will be weakened, and the sediment concentration will be reduced, respectively.
