Tune the Yellow River, Security Lan!Visit the Xiaolang bottom water conservancy cubs Century Project

Huanghe Ning, the world is flat. As a key control project for the development of the Yellow River governance, the small wave base project controls 92%of the watershed area, 91%runoff and nearly 100%sediment in the Yellow River. On September 14th, the interview group of "Yellow River Anlan" online theme publicity activities walked into the small wave bottom water conservancy hub to appreciate the charm of this century project.

Small wave bottom of the test

"In 2021, the small wave bottom reservoir has undergone a test." Li Peng, director of the Water Resources Division of the Water Conservancy Hub Management Center of the Langlang bottom, said that in the autumn flood last year, the Xiaolang bottom reservoir reached a historical highest water level of 273.5 meters. The small wave bottom water conservancy hub located in the middle of Sanmenxia Tongguan Station and Garden Estuary Station needs to be adjusted in the middle to avoid the upstream floods that cause threats to the downstream.

Li Peng introduced that in the test of the autumn flood, the small waves reservoir achieved the function of precisely regulating the water volume, and fully invested in the application of flood control, effectively ensuring the safety of floods in the lower reaches of the Yellow River and the safety of the lives and property of the people.

Since its completion, the small wave bottom water conservancy hub has effectively responded to the "West China Autumn Flood" flood in the Yellow River in 2003, the floods in the middle of the Yellow River in 2005 and the fall of 2011, and floods in the full flood season of 2012, 2018 and 2019.

Xiaolang bottom condenses wisdom and creation

The Yellow River is the mother river and life river of the Chinese nation, and it is also an unpleasant river. The content of the Yellow River runoff is the first in the world. A large amount of sediment is accumulated on the downstream riverbed to form a hanging river on the ground. Whenever the flood season comes or the flood is emerging, it is easy to overflow the road. After more than 30 years of exploration design and demonstration, the Yellow River Water Conservancy Committee has successfully passed the completion acceptance in April 2009 after decades of struggle.

The artificial "cleaning" the Yellow River is the creation of small waves to condense China's wisdom. Since 2002, the Yellow River water adjustment sand has been relying on the artificial adjustment of large reservoirs by relying on the power of natural reservoirs. By regulating the reservoir, the sediment that has been accumulated in the Yellow River and the reservoir will be sent to the sea in a timely manner, and the river bed is flushed. , Thereby reducing the accumulation of the storage area and the riverbed, so that the hanging river above the ground will not be raised, and the flooding ability of the main slot of the dry stream of the Yellow River is increased.

The Xiaolang bottom water conservancy hub broke the danger of "river silt high, people racing". The joint scheduling of the small wave bottom and the Yellow River dry tributary reservoir can effectively alleviate the flood threats of the lower reaches of the Yellow River, and increase the flood control standards from the Yellow River from 60 years to thousands of years; it can stop the upstream of 7.8 billion tons, so that the river bed in the lower reaches of the Yellow River In the past 20 years, it will not be raised because of the accumulated sediment, which has created a valuable time for the upstream soil and soil loss treatment and downstream river governance; using the artificial flood peak The effect of stabilizing the river, the Yellow River has become more and more secure.

Let the flood season become a "golden business card"

The flood season of the previous discussion has now become a "golden business card" here. When the small waves are adjusted with water and sand, the Yellow River flowing out of the cave on the dam. The Central Plains, which was born, looked at the sea -Xiaowei Xiaowang Waterfall, which was also unprecedented, attracting tourists not far away.

After the reservoir storage, the vast water surface, the twists and turns alleys, and the majestic mountains formed on the upper reaches of the dam. The reporter of the interview group said that after understanding the history of the small wave bottom, the dedication and wisdom of the builders of generations were convinced.
