Natural disasters are social phenomena (human activities) triggered by natural ones. Measures preventing and mitigating the disasters should match with society development. Intangible or non-monetary damages and non-structural measures should be more considered besides tangible damages and structural measures.
Based on the results of analysis and reviews on typical policies, practices and past lessons including good and bad examples around the world, particularly in Japan, the authors propose a basic framework of flood risk management adapting to climate change. Basic but crucial philosophies, policies and measures systematically are integrated into the framework and it encompasses structural and non-structural measures, and three phases risk management of before, during and after disaster. The strategies of short-term, medium and longer term flood management plans are proposed. The typical examples and technical documents useful for the management also are introduced in the paper and presentation. The framework is certainly referable for developed and developing countries and particularly useful for young engineers in flood risk management. The framework was also introduced in “Draft Guideline for Water-related Disaster Risk Management” prepared and released in November 2009 by the Task group on Disaster Risk Management in Word Federation of Engineering Organizations. The further discussions will make the framework better.
