There is a beautiful "sand painting" case in the bed of the Yellow River. How did this spectacle come into being?

Is the bed of the Yellow River beautiful now? Sand painting? Patterns are the wonders of nature, which are formed by the impact of the river on the riverbed.

Because the water and sediment regulation of Xiaolangdi Water Control Project on the Yellow River ended before the flood season, the riverbed of the valley was exposed after the water level of the winding river dropped, so people saw the Yellow River formed by the impact of the river on the riverbed. Sand painting? . Each sand painting records the traces of water erosion and various shapes formed by mud and water fission. These shapes are more like moving reliefs when shooting at high altitude.

1, water and sediment are unbalanced.

An important reason for siltation in the lower reaches of the Yellow River is the imbalance of water and sediment. Therefore, before the flood season comes every year, the Xiaolangdi reservoir hub of the Yellow River needs to carry out sediment adjustment treatment to discharge the river sediment deposited by the reservoir into the sea. However, it is precisely because of this characteristic that after the water level drops, it can form a good fission mud, and then there will be a relief seal similar to a winding path leading to a secluded place, also like a Yue Long shape, which is lifelike, magnificent, smooth and spectacular.

2. The river is suspended on the ground, and the current is swift.

The Yellow River is famous for its suspended rivers on the ground. Because it is above the ground, its riverbed can be exposed more after water transfer before the flood season. In addition, the Yellow River has its own unique characteristics. The Yellow River is choppy, the current is swift, and the upstream gap is large. It is easy to form a shape under the impact, and there are many rivers downstream, which can form rich modeling characteristics, so there are landscape paintings with different shapes. Due to the emphasis on greening, this landscape painting has evolved into a colorful oil painting. ?

3. The unique shape of the Yellow River.

The Yellow River has the characteristics of big bend and big bend, and it is shaped like a rectangle. There are many lakes and rivers, and it is easy to form beautiful lines after drying up. Didn't do it How many? The shape of the word. This is a picture of nature, lifelike.

With the strengthening of people's awareness of environmental protection, the protection of nature is getting better and better. I believe that we will have more opportunities to see nature's paintings and receive feedback from nature in the future.
