Abstract

This study presents a case study of Typhoon Maria (2018) affecting Yacheng Town, Xiapu County, Fujian Province, China, to investigate how typhoon landfall timing relative to the astronomical tide influences seawall breaching and flood evolution under storm surge conditions. The study employs the MIKE 21 model, SWAN model, and DLbreach model to simulate the breach process and flood inundation under different typhoon landfall timings. The findings indicate that the storm surge effect intensifies with earlier typhoon landfall, and the typhoon waves are positively correlated with the water level. Additionally, adjusting the typhoon landfall time by three hours earlier or later significantly reduces the flood inundation area, but adjusting it by one hour has little effect. The quantitative results are specific to this case study of Typhoon Maria at Yacheng Town. These findings provide a crucial scientific basis and reference for the formulation of disaster prevention and mitigation measures for seawalls and the design of coastal engineering projects.

台风登陆时间对海堤决口及洪水演变的影响——以台风玛丽亚（1808）为例

本文以台风“玛丽亚”（2018）为例，探讨风暴潮条件下，台风登陆时间相对于天文潮汐对海堤溃决和洪水演变的影响。本研究采用MIKE 21模型、SWAN模型和DLbreach模型模拟了不同台风登陆时间下的决口过程和洪水淹没。结果表明，台风登陆时间越早，风暴潮效应越强，台风波浪与水位呈正相关。另外，将台风登陆时间提前或推迟3小时可显著减少洪水淹没面积，但将台风登陆时间调整1小时影响不大。定量结果是针对雅城台风玛丽亚的个案研究。这些研究结果为海堤防灾减灾措施的制定和海岸工程项目的设计提供了重要的科学依据和参考。

期刊介绍： The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
