Abstract:

Flood is one of the most serious natural disasters in the world. The evaluation on economic loss or risk from flood disasters is the basic task in the domain of flood prevention and disaster reduction, and the research on vulnerability is key to the evaluation. This paper briefly describes the methods of vulnerability assessment, emphasizing on stage-damage curves. The origin, the methods to structure them and the compositive application are discussed then. Compared to the rich research results overseas on the damage curves, the research on vulnerability is far from enough in China yet and the application at a lower level can neither satisfy the damands for decision- support, nor correspond to the high flood risks in China. At present, scientific research, insurance and government should cooperate in the vulnerability investigation in order to reduce the influence of floods.

Key words: economic loss, flood, risk, stage-damage curve, vulnerability
