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.
