Excuse me, why are there so many floods in the south?

Because the southeast of our country faces the sea and belongs to the monsoon climate, every summer, the southeast monsoon blows from the sea, bringing a lot of rain, first to the south, and then to the north as the monsoon continues, but if you stay in the south for a long time, the south will produce water and the north will be short of water.

The plain of the two lakes has been one of the worst flood disaster areas in China for many years, because the Jingjiang River, the most dangerous in the Yangtze River, is here, where there are many rivers and lakes. When there is a flood, catastrophic floods often occur because of the water level difference (coming out of the Three Gorges) and the vast plain.

Extended data:

Flood control method

1. Increase vegetation coverage, especially forest coverage, increase storm and flood cycle, reduce peak flow and increase flow in dry season.

2. Floods are mainly caused by heavy rains, and the whole basin systematically reduces the reservoir capacity before the rainy season.

3. When the rainstorm forms a flood peak, the reservoirs in the whole basin block the flood peak, that is, reduce the total flood peak.

4. Restore occupied flood control rivers, natural lakes and reservoirs, flood storage and detention areas, and intercept flood storage peaks.

5. Passive flood control method, sensitive buildings and important production and living facilities are arranged above the flood control level.
