：了解海浪和风暴潮的未来变化对于评估和减轻气候对沿海、海洋和海洋环境以及工程问题的影响非常重要。本文综述了气候变化对日本沿海灾害影响的最新研究成果。首先，基于MRI-AGCM集合实验总结了未来波浪气候和风暴潮的变化。其次，将沿海灾害预测在沿海结构和海滩剖面上的应用总结为一系列气候影响评估项目。日本等西北太平洋中纬度热带气旋主导区波高和风暴潮极值明显增加。考虑到海平面上升、极端波浪条件和针对日本太平洋一侧的风暴潮，讨论了未来气候变化对沉箱防波堤的影响。
: Understanding future changes of ocean waves and storm surges is important for assessing and mitigating the impact of climate on coastal, marine and ocean environments and on engineering problems. This paper reviews the latest research results of climate change impacts on coastal hazards in Japan. First, future changes of wave climate and storm surges based on MRI-AGCM ensemble experiments are summarized. Second, the applications of coastal hazard projections to coastal structures and beach profiles are sum-marized as a series of climate impact assessment projects. There are clear increases in extreme values of wave heights and storm surges in the tropical cyclone dominant regions around the middle latitudes of the Western North Pacific including Japan. The influence of future climate change on caisson breakwaters is discussed considering sea level rise, extreme wave conditions and storm surges targeting the Pacific side of Japan.
