The Yellow River 22022 Water adjustment before the flood and the successful end of reservoir sand discharge and ecological hydration and other established goals

In order to maintain the Zhongshui River tank in the lower reaches of the Yellow River, realize the sand discharge of the small wave bottom reservoir, implement the Yellow River ecological scheduling and the Ecological replenishment of the Delta, and the Ministry of Water Conservancy has closely grasped the "beef nose" of the regulation of water and sand. Combined with the requirements of the Yellow River reservoir, the Yellow River Water Conservancy Committee ("Yellow Committee") organized the Yellow River Water Resources Committee ("Yellow Committee") from June 19 to July 7, and implemented the Yellow River before the flood of the Yellow River in 2022.

Li Guoying, deputy commander of the National Defense General Defense and Minister of Water Resources, attaches great importance to the work of the Yellow River's water and sand, and puts forward clear requirements. Wang Annan, executive deputy commander of the general executive of the Yellow River Defense and the director of the Huang Committee of Huang, presided over a special meeting and went to the Xiaolangdi Reservoir to guide. The Yellow Committee overcame the unfavorable factors such as the upstream water, the coexistence of droughts and floods in the basin, the underwater and the Dawen River Water System of the downstream. Increase the under -leakage flow level by step, and accurately connect the process of large traffic. From the early morning of July 4th, the small wave bottom reservoir entered the sand discharge stage. As of 22:00 on July 7, the adjustment process was over. The maximum traffic of the station is 4660 cubic meters per second, and a total of 166 million cubic meters of ecological hydration from the estuary Delta ecology has been cumulative. The comprehensive benefits such as hydration and inspection of the adaptability of downstream river channel rectification projects have explored the laws of reservoir sand and downstream rivers and sediment togans, and enriched the theory of water regulation.

In order to ensure the safety of engineering, beach areas, and wading production, before the water regulation, the Yellow Committee issued a notice to relevant departments such as Shanxi, Shaanxi, Henan, Shandong and other provinces, and water conservancy hubs and power grid management units to report the relevant situation of water adjustment and sand. Subscribe clear requirements for the prevention of water and drought disasters during the water -regulating period. Strict implementation of various responsibility systems along the yellow governments at all levels, do a good job of investigating and rescue, and strengthening the water -related safety management; the river affairs department strengthens hydrological monitoring and forecast, strengthens the joint dispatch of water engineering The scheduling instructions ensure the smooth progress of water and sand and sand.
