Methodology for Storm Surge Risk Analysis

China is largely affected by marine disasters because of her long coastal line, and storm surge is the most of all. The loss of storm surge disaster annually reaches tens of billion RMB. With the change of focus from disaster reduction (DR) to disaster risk reduction (DRR), risk reduction is paid more attentions and it is gradually considered as an important step in real disaster mitigation activity. In this paper a preliminary methodology for storm surge disaster risk analysis is provided. Disaster risk is controlled by disaster affecting intensity and disaster stakeholder character. The concept model is like this, risk = hazard ^* vulnerability. How to measure and calculation hazard and vulnerability is the key question to answer in this paper. An operational hazard index and vulnerability index system is designed to measure hazard intensity and disaster stakeholder characters. Based on geographic information systems(GIS), a case study is provided in Huanghua county of Hebei province in China, the risk analysis model is used to create storm surge disaster risk index map in case study area. The result is useful in storm surge disaster mitigation planning and other activities.
