The main functions of Xiaolangdi and its role in harnessing the Yellow River

The main functions of Xiaolangdi and its role in harnessing the Yellow River are as follows:

The Yellow River in Wan Li is vast. The Yellow River is the mother river and life river of the Chinese nation, and it is also an unruly river of worries. The sediment concentration of the Yellow River runoff ranks first in the world, and a large amount of sediment is deposited on the downstream riverbed, forming a suspended river on the ground. Whenever the flood season comes or there is a sudden flood, it is easy to overflow and divert.

As the largest regulating reservoir in the middle and lower reaches of the Yellow River, Xiaolangdi Reservoir is like a huge sapphire embedded in the mountains where Chinese civilization originated. Xiaolangdi water control project is the key control project of the Yellow River regulation and development.

On September 14, the reporter from China Industrial Network came to Xiaolangdi Water Control Project with the interview group of the Yellow River An Lan theme publicity activities to experience the achievements of decades of struggle to control the Yellow River.

Flood control has become the only way for a long river. In 202 1 year, the worst autumn flood occurred in the middle reaches of the Yellow River since the founding of the People's Republic of China. Facing the severe test, Xiaolangdi Water Control Project has avoided the forced relocation of the people in the downstream beach area and ensured the safety of the middle reaches of the Yellow River.

Yellow river expansion

1, using the relatively large storage capacity of Xiaolangdi to intercept the flood in the case of upstream flood. For example, at the Huayuankou of the Yellow River in Zhengzhou, this is a weak link in the flood control of the Yellow River.

2. Before the flood season every year, Xiaolangdi Water Control Project will carry out water and sediment regulation. In this way, the large flow is manually controlled to scour the downstream river channel, and the flood discharge capacity of the downstream river channel is increased.
