China is one of the most serious countries of marine disasters in the world, and the main marine disasters comprise storm surge, tsunami, sea ice, sea wave, red tide and the like, wherein the marine disasters with the greatest harm belong to storm surge and tsunami. In 2017, typhoon "Tiange pigeon" lands just in astronomical tides, and brings about great damage to areas such as the Zhuhai, hong Kong and Macau, which causes 24 deaths and economic loss of $ 68.2 hundred million. Tsunami 3 months and days in 2011 caused 8133 deaths, 12272 losses and more than 2000 billion economic losses. In 1953, a strong storm surge which occurs on the coastal areas of the Netherlands causes the water level of the storm surge to be more than 3 meters higher than the normal tide level, the protection dike is washed out, 80 ten thousand acres of land are submerged, and more than 2000 people die.
