名古屋市民100万人に避難勧告の出た2011豪雨-2000東海豪雨との比較による豪雨災害への対応-

抄録

On a heavy rainfall in September 2011, Nagoya city issued evacuation recommendation to more than a million citizens and resultantly only around 4800 citizens followed. When we have to prepare for coming serious disaster due to climate change to overcome remained vulnerability, it is necessary to study how to manage risk against severe heavy rainfall and subsequent flood disasters. Then it is important to compare this time event with Tokai heavy rainfall disaster in 2000 when we discussed how to overcome urban flood disaster due to a torrential downpour and continued improvement of preparedness against it. This study aim to compare two events in 2000 and 2011 each other, to clarify how we have advanced our preparedness against heavy rainfall disasters, and how to overcome remaining difficulties, from the conceptual discussion of risk management composed of the concepts of hazard, exposure and vulnerability (or resilience).
