Spring flood season is also called "peach flood season" and "peach flood season". The phenomenon that the water level of the river rises in spring. It is mostly caused by spring climate warming and melting of snow and ice, and there are also heavy rains and even heavy rains caused by alternating cold and warm air currents.

What is a summer flood?

1, rainy season is frequent in summer, and heavy rain is concentrated during this period, which is easy to cause waterlogging.

2. In fisheries, summer is the season of concentrated fishing for certain fish or aquatic products.

PS:: 1。 Most inland rivers in northwest China are in the summer flood period. Because their river recharge type is glacial meltwater! In summer, the temperature is the highest and glaciers melt the fastest, so rivers supply the most.

Most rivers in the northeast of China are in spring. Because their river recharge type is seasonal snowmelt water! In spring, the temperature warms up, and the snow on the mountain melts quickly, increasing the water volume of the river.

River recharge in North China, Huanghuai and South China is generally groundwater and rainfall recharge, and there is much precipitation in summer, which is easy to form summer floods.

2. Ice flood, commonly known as ice raft, is a hydrological phenomenon of river flood caused by ice jam. Ice sometimes converges into an integrated ice plug or dam, which leads to a sharp rise in water level and eventually floods the beach or bursts its banks. This is the so-called Hong Ling. Ice flood may occur during the interception period in winter and the river opening period in spring.
