Storm surge inundation can induce great disasters in coastal regions, and Laizhou Bay (LZB), located in the Bohai Sea, is a bay that frequently experiences coastal storm flooding. In this study, we perform a numerical study of the effects of wind and waves on the storm surge-induced coastal inundation in the LZB using the coupled model ADCIRC+SWAN. Two historical typhoons (No. 9216 Typhoon Polly (TY9216) and No. 1909 Typhoon Lekima (TY1909)) are considered, wave effects in terms of wind-wave-induced surface stress and radiation stress are included, and two widely used wind data sources (CFS and ERA5) are used. The results indicate that the total inundation area and average inundation depth in the LZB during TY1909 are 10.70%-19.16% larger than during TY9216, and the CFS wind field reproduces a 14.31%-23.05% more intense inundation simulation than does the ERA5 wind field. The wave-induced surface stress plays the primary role in increasing the inundation area and average depth by up to 11.42%-18.50% and 5.82%-8.75%, respectively, and the wave-induced radiation stress also increases the inundation area and average depth by 3.80%-6.60% and 3.70%-4.57%, respectively. The results highlight the importance of considering wave effects in storm surge-induced coastal inundation simulations, and we demonstrate that the wave effects on the inundation area can be quite sensitive to the choice of wind field source.

风暴潮淹没会在沿海地区引发巨大灾害，而位于渤海的莱州湾（LZB）是沿海风暴洪水频繁发生的海湾。在这项研究中，我们使用耦合模型 ADCIRC+SWAN 对 LZB 风暴潮引起的沿海洪水影响进行了数值研究。考虑两个历史台风（9216 号台风波利（TY9216）和 1909 号台风利奇马（TY1909）），包括风波引起的地表应力和辐射应力方面的波浪效应，以及两个广泛使用的风数据源（CFS 和 ERA5）被使用。结果表明，TY1909期间LZB的总淹没面积和平均淹没深度比TY9216期间增加了10.70%-19.16%，CFS风场再现了14.31%-23。比 ERA5 风场强 05% 的洪水模拟。波致地表应力对增加淹没面积和平均深度起主要作用，分别增加了11.42%-18.50%和5.82%-8.75%，波致辐射应力也增加了淹没面积和平均深度分别为 3.80%-6.60% 和 3.70%-4.57%。结果强调了在风暴潮引起的沿海淹没模拟中考虑波浪效应的重要性，并且我们证明了波浪对淹没区域的影响对风场源的选择非常敏感。波浪引起的辐射应力也使淹没面积和平均深度分别增加了3.80%-6.60%和3.70%-4.57%。结果强调了在风暴潮引起的沿海淹没模拟中考虑波浪效应的重要性，并且我们证明了波浪对淹没区域的影响对风场源的选择非常敏感。波浪引起的辐射应力也使淹没面积和平均深度分别增加了3.80%-6.60%和3.70%-4.57%。结果强调了在风暴潮引起的沿海淹没模拟中考虑波浪效应的重要性，并且我们证明了波浪对淹没区域的影响对风场源的选择非常敏感。
