Characteristics and numerical simulation of typhoon storm surge in the Eastern Guangdong sea area

The Eastern Guangdong coastal region is one of the most developed economies in China,and is also one of areas suffered the storm surge disaster.The characteristics of typical storm surge since 1969 is analyzed.In order to better relief the storm surge disaster of the Eastern Guangdong coastal region,a new storm surge mod-el is established to simulate and forecast the storm surge.The model,with a variable grid,could not only cover a large enough area,but also distinguish the tiny topography of bays,estuaries and so on.The model is used to simulate an historical worst typhoon storm surge event,and shows its excellent applicability.The model can also be used in other areas to better serve the work of marine disaster prevention and mitigation.
