京都大学防災研究所防災技術政策研究分野

Welcome to Sayama Lab.

Our laboratory is the Innovative Disaster Prevention Technology and Policy Research (Sayama Lab.) at the Disaster Prevention Research Institute (DPRI), Kyoto University, and belongs to the Research Division of Disaster Management for Safe and Secure Society, under Integrated Arts and Sciences for Disaster Reduction Research Group.

Our team includes faculty members, researchers, and staff at DPRI, together with students from Undergraduate School of Civil, Environmental and Resources Engineering and Department of Civil and Earth Resources Engineering, Graduate School of Engineering.

We share a common mission: to reduce water-related disaster risks. To achieve this, we combine technology and policy perspectives and carry out our research around three core missions.

1. Scientific understanding of water-related disasters from nature to society
   We observe, understand, and model natural processes such as rainfall–runoff and flood inundation based on hydrological science. At the same time, we focus on social factors that shape disaster risks, analyzing their structures through field surveys and both qualitative and quantitative data. Through this integrated approach, we aim to clarify the multi-layered mechanisms of water-related disasters.
2. Analyzing water-related disaster risks and proposing innovative solutions with technologies and policies
   We work on developing new technologies such as real-time flood forecasting, statistical analysis of extreme events, and modeling of compound disasters. By combining these with social factors including exposure and vulnerability, we analyze water-related disaster risks. Based on these findings, we propose policy options on land use and disaster recovery that contribute to disaster risk reduction (DRR).
3. Translating knowledge into practice and contributing to reducing disaster risk step by step
   In collaboration with governments, municipalities, and private sectors, we put our research into practice in the field while feeding back field-based insights into research. By disseminating research outcomes domestically and internationally, we contribute to reducing water-related disaster risks and enhancing societal resilience.
