Abstract: Thailand has been recently assessed by several organizations for the risk and vulnerability to climate change disasters (Floods, Drought, storms). By the same time, the coping capacity especially, adaptations have never been completely investigated. This was evidenced by the 2011 great flood which Thailand could not cope with great disasters causing significant impacts on both human and assets. This event has been recorded as the most economic damage, approximately 1.44 trillion Baht reported by the World Bank. Looking back in the past 10 years (1995-2006), there were 54flood events causing 2,682 deaths, 30 million affected people, and 135 billion-Baht total losses. Bangkok suffered severe floods in 1983,1995,2006 which was the initiation of several flood defense projects. However, Bangkok is still under threat of flooding, especially the increasing flood risk due to climate change and the rapid urbanization in the floodplain. The frequency of devastating floods tends to be higher and the loss of human lives and property show increasing sign. The present paper investigates the flood behavior for the 2011event which includes the lesson learnt, pre-during-post flood management. The flood impact assessment has been done considering the climate change impacts in term of increasing rainfall and sea level rise according to the IPCC SRES scenario. Finally, preliminary assessment is made to study suitable structural measures to mitigate the flood impact following the 350 billion-Baht water management project.
