Our research laboratory aims to elucidate natural and social phenomena related to water disasters and to propose new technologies and policies for risk reduction, and we conduct our research and education activities based on the following three approaches.
Research Approach ①:
Understanding diverse aspects of water-related disasters
Our work begins with observing and modeling hydrological processes, especially the mechanisms linking rainfall-runoff and inundation. We also study social factors that shape disaster risks, combining quantitative and qualitative methods such as field surveys, interviews, and questionnaires. Post-disaster investigations are another key approach, helping us capture the realities of damage and better understand how risks are formed.
Research Approach ②:
Developing technologies and policies for risk reduction
We explore new directions in both technology and policy to reduce water-related disaster risks. Our research includes integrated rainfall–runoff–inundation prediction, real-time flood forecasting, analysis of extreme events under climate change, compound disaster modeling, and extreme value statistics. Beyond physical hazards, we also study social dimensions such as exposure and vulnerability, aiming to clarify the structural drivers of disaster impacts. From this, we propose measures on land use, disaster recovery, and governance that support disaster risk reduction.
Research Approach ③:
Putting knowledge into practice
We place strong emphasis on applying our findings in real-world contexts. Through projects such as SIP (Cross-ministerial Strategic Innovation Promotion Program), we work with governments and municipalities to implement new technologies in disaster risk reduction. These efforts also provide feedback from the field, helping us refine research agendas. Our faculty engage in policy-making committees and collaborate with private companies in construction, engineering, weather services, insurance, and risk management. By gradually introducing innovations into society and sharing our practices globally, we aim to enhance resilience and contribute to broader social change.
