中文摘要: 河口围涂工程建设将不同程度影响工程海域的水沙输移特性。运用平面2维潮流数学模型,以浙江温州瓯飞滩围涂工程为例,研究河口大规模围涂工程对周边水动力环境的影响。基于三角形网格,采用有限体积法对模型进行求解,通过9个实测潮位过程和9个流速测点对模型进行验证,验证结果良好。瓯飞工程实施后,海域高潮位呈现一定程度的降低,围堤前沿水域流速大幅度降低,但对温州核心港区影响较小,飞云江口进出潮量有所降低,研究成果可为工程决策提供重要参考依据。
Abstract:The local landform will be changed after reclamation through sea-dike building.It will affect the character of tide and tidal current,and the sediment transporting near the reclamation region.Taking the shore reclamation between Oujiang and Feiyunjiang Estuary as example,a tidal current mathematical model was used to study the effects of the hydro-dynamic environment due to the large-scale reclamation.Based on triangle grid and finite volume method,the flow model was examined by observed tidal level stations and synchronous vertical lines.Tthe comparison between computed result and measured solution showed very good agreement.After the project building,the high tide level reduced to some extent and the flow of front reclamation line reduced by a big margin.But it had a little influence on the core ports of Wenzhou.And the tidal influx through Feiyunjiang Estuary kept decreasing.The result can be used as a reference and inspiration for the effects of the large-scale reclamation projects on hydro-dynamic environment.
