Abstract

The invention discloses a typhoon storm surge risk assessment method and a system based on an ArcGIS platform. The method has the advantages that compared with a traditional storm surge risk zoning strategy, the risk quantitative evaluation strategy is provided, and quantitative calculation is conducted on each factor (H, E, V and R) influencing the final risk value of the area to be evaluated. Therefore, the final risk value can be measured from two perspectives, one is a traditional risk level form, the other is an innovative quantitative mode, and a specific risk value can be obtained. Andthe method has important significance for disaster prevention, disaster reduction and disaster relief deployment. Meanwhile, only three parameters are considered at most in traditional risk division,an algorithm is provided for detailed calculation of each parameter, meanwhile, the disaster prevention and reduction capacity is considered, and therefore the completeness and reliability of an evaluation result are further improved.

Description

technical field [0001] The invention relates to the fields of disaster prevention and mitigation and disaster assessment, and mainly refers to the risk assessment and planning of typhoon storm surges in coastal areas based on the ArcGIS platform. Background technique [0002] A storm surge is a rise and fall of sea water due to severe atmospheric disturbances, such as strong winds and sudden changes in wind pressure (usually referring to disastrous weather systems such as typhoons and extratropical cyclones), causing the affected sea area to greatly exceed the normal ultramicro Phenomenon. Storm surges are often accompanied by strong winds and huge waves. If they are superimposed with astronomical tides, they will often result in tidal protection in coastal areas and lead to huge disasters. China is located on the west coast of the Pacific Ocean, with a continental coastline of more than 18,000 km. It is one of the few countries in the world most severely affected by storm ...
