Rivers in China are divided into inland rivers and outflow rivers, and inland rivers mainly rely on snowmelt water for water supply. During the high temperature period from May to September, the amount of snowmelt increased, forming a flood season.

The outflow of river water depends on atmospheric precipitation, and the rainy season forms the flood season. The precipitation is mainly concentrated in the southern coast, which affects the Yangtze River basin.

In June, July and August, the rainfall in Northeast China and North China began to withdraw southward in September, so it takes about 5-9 months for the flood season to flow into and out of the river.
