Abstract:

In order to facilitate engineering design and coastal flooding protection, the potential storm surge induced by a typhoon is studied. Using an unstructured mesh, a coupled model which combines the advanced circulation(ADCIRC)hydrodynamic model and simulating waves nearshore(SWAN)model is applied to analyze the storm surge and waves on the coast of Jiangsu Province. The verifications of wind velocity, tidal levels and wave height show that this coupling model performs well to reflect the characteristics of the water levels and waves in the studied region. Results show that the effect of radiation stress on storm surge is significant, especially in shallow areas such as the coast of Jiangsu Province and the Yangtze estuary. By running the coupled model, the simulated potential flooding results can be employed in coastal engineering applications in the Jiangsu coastal area, such as storm surge warnings and extreme water level predictions.

为了方便工程设计以及沿海防洪减灾, 对可能由台风引起的风暴潮进行了研究.利用三角形非结构网格建立ADCIRC水动力模型和SWAN波浪模型的耦合模型, 并将其应用于江苏沿海风暴潮和波浪研究.风速、潮位和波高的验证表明该ADCIRC+SWAN耦合模型可以很好地模拟研究区域的水位和波高.研究结果表明辐射应力对风暴潮计算结果有影响, 且在如江苏沿海和长江口此类的浅水区域影响更为显著.模型计算的水位结果在江苏沿海得到工程应用, 例如风暴潮预警和极端水位预测.
