This year's floods have caused disasters, so how did the domestic floods form?

The frequent floods in the south this year have had a great impact on the lives and work of the people in the south. The country is also doing its best to rescue and provide disaster relief, and many soldiers come to the front line to protect people's lives and property.

The formation of floods is largely related to natural factors. We know that in ancient times, the floods in the south of the Yangtze River were very serious, which also became a problem that troubled many generations of monarchs. During the Spring and Autumn Period and the Warring States Period, the completion of Dujiangyan and Zheng Guoqu solved the flood disaster to a great extent and was also beneficial to farmland irrigation, which was a major project in ancient times. It can be seen that flood disaster has been a problem since ancient times.

First of all, the most common cause of floods is continuous high-intensity precipitation. In the southern summer flood season, there is more rain and continuous rainfall. In this way, a large amount of rainwater flows into the river, and urban rainwater will also be discharged into the river, resulting in a large number of rivers. At this time, if the relevant government departments do not take measures to prevent floods, it will lead to the outbreak of floods.

Secondly, the storm surge is coming. When we watch the weather forecast, we often hear the words ocean current, monsoon and typhoon. Due to the movement of ocean currents, summer monsoon and winter monsoon are formed, and summer peak brings a lot of precipitation to China's coastal areas, which is also the reason for the large increase in rainfall in the south. I often hear about typhoons landing recently, so the recent continuous precipitation in the south is largely due to the arrival of storm surges.

Thirdly, the melting water of icebergs will replenish the river. In summer, due to the sharp rise in temperature, the blood after melting icebergs will flow into the river along the valley and become an important part of river water supply.

Finally, because of some special disasters, such as earthquakes and tsunamis, the earth is also a living body. When natural disasters break out, it will also have a linkage effect on other aspects.
