Waterlogging refers to a meteorological disaster caused by excessive precipitation for a long time or regional rainstorm, which causes River flood overflow, inundates farmland and urban and rural areas, or generates ponding and runoff to inundate low-lying areas, resulting in agricultural or other property losses and casualties. This atlas mainly analyzes the rainfall and waterlogging in humid and semi nirun areas in China.
Most areas of China have suffered from rain and waterlogging disasters, among which most of the Northeast, the east of North China, Huanghuai, Jianghuai, Jianghan, Jiangnan, South China, and the east of Southwest China generally have an annual rainfall frequency of more than 5%. The high frequency of rainfall and waterlogging is mainly located in most of South China, most of Jiangnan, east of Jianghan, west of Jianghuai, Southeast of Huanghuai, North and west of Sichuan Basin, southwest of Guizhou, south of Yunnan and east of Liaoning. The annual frequency of rainfall and waterlogging is generally more than 30%, and more than 50% in some areas.
