AboutAbout the lab
Reducing water disaster risk through technology and policy
The Disaster Prevention Technology and Policy Lab conducts research to reduce the risk of water disasters such as floods and inundation.
Based on hydrology, the lab models the whole process from rain falling on mountains, to its runoff into rivers, to its overflow into towns.
The lab also studies how climate change will alter disasters, and how land use and the way recovery is carried out affect risk.
The technologies the lab develops are used in the field by local governments and national government, and the knowledge gained there is fed back into research.
Key terms
- Hydrology
- The study of how water moves around the Earth, including rain, rivers, and groundwater
- Rainfall-Runoff-Inundation (RRI) model
- A model that calculates, in one continuous process, how rainfall runs off into rivers and how water overflows from rivers and spreads
- Extreme value statistics
- A statistical method for estimating from past records how likely rare, large events are to occur

ResearchResearch themes
The lab advances research on reducing water disaster risk from both technology and policy sides. While modeling the mechanisms of rainfall runoff and flood inundation, it also captures the social factors that shape risk through field surveys.
*Illustrative imageAdvancing flood prediction and its applications
Through field observations and theoretical analysis, the lab clarifies how heavy rain falling on mountains runs off into rivers. By applying the Rainfall-Runoff-Inundation (RRI) model nationwide, the lab has achieved real-time flood prediction that includes small and medium-sized rivers.
*Illustrative imageAssessing the impacts of climate change
To predict how the frequency and scale of water disasters will change in the future, the lab develops methods themselves, such as bias correction and multivariate extreme value statistics.
*Illustrative imageWater disasters and society
Focusing on rural areas in the Philippines, peatlands in Indonesia, and disaster recovery in Brazil, the lab examines the relationship between water disasters and society through field surveys and questionnaires.
