Flood season is a water conservancy term, which refers to the period when the river flows regularly and significantly in a year.

Due to the different geographical location and flood season, the length and time sequence of flood season are also different. In spring, the climate gets warmer, seasonal snow melts, river ice melts or spring rain causes the river to rise, which is called spring flood.

In northern China, the phenomenon that the water level rises due to the melting of river ice in spring is called ice flood. In summer, the torrential rain in the basin or the melting of snow in alpine glaciers make the river rise sharply, which is called summer flood. In our country, it is customary to call the floods around the dog days in summer as the flood season. In autumn, due to heavy rain, the river surges, which is called autumn flood season.
