Abstract
Taiwan is on the typhoon path of the west Pacific Ocean Region. During summer and autumn season, typhoons always bring heavy rainfall. Extreme weather in recent years often causes severe flooding and result in serious losses of life and property. With the rapid industrial and commercial development in recent years, people care about not only the quality of life, but also the safety of life and property. So theimpact of life and property due to disaster is the most serious problem concerned by the residents. For the mitigation of the disaster impact, in addition to works by proactive way, including the disaster prevention and safety drills, mobile training relief workers to reduce the occurrence of disasters, and flood warning system, the flood hazard and risk analysis play an important role for the disaster prevention. In this study, the vulnerability of Kaohsiung city was evaluated by statistics of social development factor. The hazard factors of Kaohsiung city was calculated by simulated flood depth of six different return periods（5 years, 10 years, 25 years, 50 years, 100 years and 200 years） and four typhoon events（Tarmi, Haitang, Morakot and fanapi typhoon） which result in serious flooding in Kaohsiung city. The flood risk can be obtained by combining the flood hazard and social vulnerability. The analysis results provide authority to strengthen disaster preparedness and to set up more resources in high risk areas. The threat score of flood risk can improve the accuracy in flood warning, hence resources and relief supplies can be efficient allocated to protect lives and property during the disaster occurs.
