中文摘要：

该文基于MIKE21／3技术平台，将CoupledModelFM模型应用于瓯江口海域水动力环境的数值研究。在现场实测资料验证的基础上，对温州浅滩围涂工程周边二维波流耦合作用下的水动力环境进行了数值模拟，并对工程实施前后的波流场进行了对比分析。研究结果表明，围涂工程对S向及偏S向的波浪起到阻挡作用，并且不会大范围的改变瓯江121海域潮流的水动力特征，仅对工程附近水域产生影响，且影响幅度很小。

英文摘要：

Based on the technology platform of MIKE21/3, the Coupled Model FM model has been applied to the numerical study on hydrodynamic environment in the Onjiang Estuary. On the basis of model verification of filed measured data, the model has been applied to the numerical simulation on the two-dimensional, wave-current coupling hydrodynamic environment due to the land-making project at Wenzhou shoal. According to the simulation, the wave field and tidal flow before and after the project are compared. The study shows that the land-making project can block the spread of the S wave and partial S wave, and the project does not change the hydrodynamic characteristics of tidal flow in the whole area, but only affect the vicinity of the project, and the amplitude of the effect is slight.
