Danger of flood:

Among all kinds of natural disasters, flood is the most common and harmful. Floods occur frequently, spread widely, are fierce and extremely destructive.

Floods not only flooded houses and people, causing a large number of casualties, but also swept away everything in people's homes, including food, flooded farmland and destroyed crops, resulting in a substantial reduction in food production, which led to famine. Floods will also destroy factories, workshops, communication and transportation facilities, thus causing damage to the national economic sector.

There are many reasons for the formation of floods, mainly the destruction of the earth's vegetation, which leads to the deterioration of the natural environment and floods. For example, in Weinan, Shaanxi Province, because the water of Weihe River, Luohe River and Yellow River meets in Tongguan, the water of the three rivers can't flow downstream in time, and the whole water is collected in Huayin and Tongguan, Weinan, which makes the water of Weihe River start to flow backwards and form a flood.

The main reason is that people arbitrarily cultivate and cut down trees, resulting in the loss of protection of the surface soil on the slope, loose soil, a large amount of soil erosion, and a large amount of sediment deposited on the riverbed, which makes the riverbed rise and causes flooding. This is actually the punishment of nature for wanton destruction of the environment.

Chongqing Municipal People's Government-Chongqing issued a red flood warning for the first time in history, and the Chongqing section of the Qijiang River basin suffered the biggest flood on record.
