2018年台风“飞燕”在日本大阪湾一带造成了严重破坏。风暴过后，日本土木工程师协会（JSCE）的海岸调查小组调查了大阪湾和太平洋沿岸的海岸影响，并记录了水位。在大阪潮汐站，潮汐仪记录的最高风暴潮为3.29米，这是大阪湾的历史最高值。几乎所有地区的沿海洪水都由风暴潮和波浪上升组成，大阪湾内部和太平洋沿岸的洪水分别比平均海平面高出5米和12米。位于海岸屏障之外的地区，如港口和港口，海岸破坏严重，而由于海岸防护系统，住宅区主要得到了很好的保护和幸免。此外，由于风暴潮沿几条小河扩散，神户-阿希亚地区发生了一些内陆洪水。本调查报告总结了JSCE的事后调查结果，并分析了最高水位与造成的破坏之间的关系。
Typhoon Jebi in 2018 caused severe damage along areas of Osaka Bay, Japan. After the storm, a Japan Society of Civil Engineers (JSCE) coastal survey group surveyed the coastal impacts and recorded watermarks inside Osaka Bay and along the Pacific. The maximum storm tide recorded by a tide gauge was 3.29 m at the Osaka Tide Station, which is a historical high for Osaka Bay. Coastal flooding consisted of both storm surge and wave run-up in almost all locations, with flooding exceeding 5 m and 12 m in elevation from mean sea level in the inner parts of Osaka Bay and along the Pacific coast, respectively. Coastal damage was severe in areas located outside of coastal barriers, such as ports and harbors, while residential areas were mainly well protected and spared due to coastal protection systems. In addition, some inland flooding occurred in the Kobe-Ashiya regions due to the storm surge propagating up several small rivers. This survey report summarizes the findings of the post-event survey by JSCE and analyzes the relation between maximum water level and resulting damage.
