本研究旨在评估沿海地区混合基础设施的功能，并确定影响其可持续性的因素。本研究针对的混合基础设施位于日本德岛县南部的大户地区，由海岸、海岸堤防、海岸森林、水稻桨和沙丘组成。本研究对海啸和风暴潮进行了数值分析和实地观测。在海啸分析中，假设发生海啸、风暴潮和海平面上升等复杂灾害，评估了淹没区对参考水位的响应。在风暴潮分析中，评估了2019年日本第19号台风海贝思（Hagibis）造成海岸森林海滩变形和破坏的机制，并对历史沙丘形成过程进行了探讨。最后，讨论了混合基础设施所需的设计策略。
This study aims to evaluate the functioning of hybrid infrastructures in coastal areas and identify the factors influencing their sustainability. The hybrid infrastructure targeted in this study is in the Osato area in southern Tokushima Prefecture, Japan, and consists of a seashore, coastal embankment, coastal forest, rice paddles, and dune. Numerical analysis and field observations of tsunamis and storm surges were conducted in this study. In the tsunami analysis, the response of the inundation area to the reference water level was evaluated assuming a complex disaster involving a tsunami, storm surge, and sea-level rise. In the storm surge analysis, the mechanism of beach deformation and damage in the coastal forest caused by Typhoon Hagibis (No. 19 in Japan) in 2019 was evaluated, and the historical dune formation process was discussed in this case study. Finally, the design strategy required for hybrid infrastructure is discussed.
