Liuyang River in Xiangjiang River has become a mandarin duck pot. What's going on here?

One day in Xiangjiang River in recent years, a strange thing happened. According to our understanding, this river is called Liuyang River. Just in July of these years 1 1, one side of this big river became clear, but the other side turned yellow, and it was so turbid that it was scolded by many people? Yuanyang pot? . ?

As far as we know, this interesting photo was taken by Xie Ming, a photographer in Changsha, Hunan Province, with a drone. In recent years, in July of 10, there was a heavy rain in Liuyang, which lasted for a long time and then there was a flood. On July 1 1 day, Liuyang River turned yellow, but Xiangjiang River was crystal clear. Teacher Xie Ming showed that this is because the velocity of Liuyang River and Xiangjiang River are different, and the width of the river is also different. Every time there is a flood in these places, the river will change and the color will change strangely after the flood comes, which is different.

Most of the reason is that the flash floods after the rainstorm have flowed into Liuyang River, because their water levels are different. It is understood that the largest flood peak in history passes through Changsha. Xiangjiang Changsha Station is located at 38.3 1 m, the warning water level is 2.3 1 m, and the flow reaches 25,300 cubic meters per second. After testing, the historical maximum flow rate is about 20800 cubic meters per second.

It is difficult to be polluted in such a terrible current. That is to say, the Liuyang River in Xiangjiang River is not so horrible, and because the flow is not very large, it is easy to be polluted, so it is very small compared with the Xiangjiang River with large flow, so this will happen. Therefore, it has formed a turbid and crystal-clear spectacle. Therefore, while enjoying the beautiful wonders, we should also remind everyone to pay attention to flood control and disaster relief, because floods will bring us a lot of harm and trouble, so we should be prepared for flood control. For everyone's personal safety, we must remember to protect our environment so as to avoid disaster.
