On the Risk Assessment of Storm Surge Disasters in the Coastal Areas of Qingdao

Based on the regional disaster system theory, the risk and vulnerability of storm surges in the coastal areas of Qingdao are assessed quantitatively and qualitatively respectively, and a risk index system of storm surge disasters in coastal areas of Qingdao is constructed in this paper. A storm surge inundation model is employed to calculate and determine the storm surge inundation areas and depth of the maximum probability, and the risk assessment of storm surges in different regions is performed. Based on the land classification for exploitation and utilization, the vulnerability of different regions is evaluated and classified. The risk of storm surge disasters in the coastal areas of Qingdao is classified with the aid of GIS spatial analysis. This assessment and classification system is scientific and user friendly, and the assessment results can be used straightforwardly to determine the risk of a hazard-bearing body, which provides guide and suggestions to hazard prevention and land utilization.
