Knowledge Notes　～ Learning from Japan's Experience in Integrated Urban Flood Risk Management～

Cutting-edge information on urban flood management

The four-part series “Learning from Japan’s Experience in Integrated Urban Flood Risk Management: A Series of Knowledge Notes” was prepared by a World Bank team and Yachiyo Engineering Co., Ltd. This series of knowledge notes contains many of the key lessons learnt from Japan’s IUFRM efforts. While any strategy for reducing disaster risk must be developed based on a close understanding of local contexts, the aim of this series is to help members of the international community improve their own approaches to managing urban floods. Importantly, IUFRM considers multiple types of floods that may occur individually or in combination: river floods, surface water floods, and storm surge floods. These notes are not intended to provide a comprehensive analysis but rather a snapshot highlighting key aspects, practice, and lessons learnt from Japanese practice.

The four knowledge notes in this series cover urban floods from assessment and planning through the implementation and maintenance, in the following order:

1) Urban Flood Risk Assessment and Risk Communication
2) Urban Flood Risk Reduction Investment Planning and Prioritization
3) Designing and Implementing Urban Flood Risk Management Investments
4) Ensuring Sustainability through Operations and Maintenance
