Outline of Final Research Achievements

Using a discrete damage estimation method, damage to water pipelines was estimated. A numerical analysis model was developed to evaluate functionality of water for firefighting based on pipe network analysis in EPANET. The analysis of water use for firefighting against recent fires in buildings was conducted. It was shown that firefighting water use for building fires is dependent on fire hydrants. The relationship between the amount of water discharged per building fire, the area of fire damage, and the time of water discharged was examined.
A " platform" was created for industry, government, and academia in the fields of water supply and firefighting to discuss and examine the future firefighting capability of the community in a interdisciplinary approach. It was indicated that it is important to ensure the future firefighting capability of the community and to create a safe and secure community through interdisciplinary and industry-government-academia collaboration.

Academic Significance and Societal Importance of the Research Achievements

本研究では，人口減少社会に向けた水道管路の減径と地域の消防水利とはトレードオフ関係があり，地域の消防力確保においては，水道分野と消防分野での連携技法が必要不可欠であることを指摘した。すなわち，既往の検討においては，水道分野、消防分野でのそれぞれの検討にとどまるものであったが、本申請研究成果により、将来の地域の消防力を担保し、安全・安心な社会の創生のため，今後，これらの学問分野の連携を図り、地域主体での分野横断的かつ産官学連携の取り組みに資するものである。
