The hazard-formative environment evolution of storm surge hazard in Yang Shan Port, China

Oceanic disasters, especially the storm surge hazard, occur with increasing frequency and intensity in coastal areas. Yang Shan Deep-water Port, the most important gateway of China to the world, is exposed to a high disaster risk. The analysis of its hazard-formative environment is the basic work to find appropriate measures to reduce the risk. In this work, the evolution of the hazard-formative environment of storm surge hazard in Yang Shan Deep-water Port is studied systematically by Geographic Information System (GIS) spatial analysis techniques. The results indicate that the hazard-formative environment in Yang Shan Port has changed a lot due to human disturbance in recent years, and the evolution of this environment will lead to a higher potential risk of disaster with global climate change.
