    摘要
  • 基于ROMS海洋模式，结合近年的地质实测资料，建立了渤海湾西部地区风暴潮漫滩的数值模型。对模型进行验证后,对渤海湾西部区域重现期为50a、100a、200a及500a的风暴潮漫滩进行了数值模拟，分析了不同重现期风暴潮漫滩发展的动态过程及最大漫滩淹水范围。结果表明，数值模型基本能反映风暴潮的增水趋势，能够模拟风暴潮漫滩发生发展的动态过程。随着风暴潮强度的增加，渤海湾西部地区淹水范围具有从东海岸向西部内陆区域扩展的趋势。通过曲线拟合发现，风暴潮最大漫滩面积比值与高水位之间基本呈线性关系。
    Based on ROMS (Regional Ocean Modeling System) ocean model and the geological measuring data obtained in recent years, the authors developed a storm surge and inundation numerical model for the west zone of Bohai Gulf. The numerical model was verified. After that, the inundations caused by storm surge with return periods of 50a, 100a, 200a and 500a in the west zone of Bohai Bay were simulated. In addition, the dynamic development process and the maximum inundated area of storm surges for different return periods were analyzed. The results showed that the numerical model could basically reflect the change trend of storm surges elevation and the dynamic process of the occurrence, and the present model could simulate the development of storm surge inundation. With the increment of the density of the storm surge, there was an obvious trend that the inundated areas expanded from east coast to western inland in the west zone of Bohai Bay. Through the curve fitting method, it was found that the relation between the ratio of maximum inundated areas and the flooding level was approximately linear.
