Outline of Final Research Achievements	In recent years, flood disasters have often occurred due to floods, tidal waves, and tsunamis. The authors focus on protecting houses, property, and lives from damage caused by flood disasters. In this study, a floating disaster prevention house was proposed. The authors focus on protecting houses, property, and lives from damage caused by flood disasters. In this study, a floating disaster prevention amphibious house was proposed. The following research tasks were carried out: 1) development of the flood disaster reproduction device using a circulating water channel, 2) consideration of the disaster prevention performance of the flood wall and the floating unit, and 3) preparation of the numerical simulation method using the MPS method. Finally, the results of the water tank experiment and the numerical simulation revealed the essential disaster prevention performance of the floating disaster prevention house.

Academic Significance and Societal Importance of the Research Achievements	現在、世界的な地球温暖化に伴う水害に対する住居の防災・減災対策が求められている。近年、我が国では数年に一度沿岸域の津波被害が発生しており、また洪水等の水害は毎年のように発生している。しかしながら、現状においては堤防などの治水による防災対策やハザードマップによる避難指示が中心であり、陸域への浸水が発生してしまった状況における対策は十分に検討されていない。住居を守ることは被災者の生命および財産を守ることである。浮上式防災住居はそのような課題を解決することができる可能性を有しており、浮上式防災住居が実用化されれば、水害に対する防災・減災対策および人命の保護に大きく寄与できると考えられる。
