Tongguan station will have the biggest flood since 1996. How will the relevant departments respond?

According to the report of relevant departments, the flood of the Yellow River will reach 6600 cubic meters per second, which may become the biggest flood in Tongguan Station since 1996. The personnel of relevant departments said that they will take countermeasures in advance in combination with the flood situation in the upper, middle and lower reaches. The Three Gorges Reservoir continued to discharge flood, and at the same time started the defense of flood control or drought and flood protection in the middle and lower reaches of the Yellow River. Under the joint dispatch of relevant departments, the flood discharge capacity of Xiaolangdi Reservoir can reach 4000 cubic meters per second. It has affected the normal production and life, because the recent heavy rainfall in the middle reaches of the Yellow River has greatly affected the normal production and life of nearby residents. On the 20th, the first flow of the Yellow River reached 2750 cubic meters per second. Due to the confluence of the Weihe River and the North Yellow River and the water from the central region, the relevant departments predict that the Tongguan Station of the Yellow River will have a peak flow of 6600 cubic meters per second at around 2 1, and the relevant personnel predict that the flood volume will reach about 3.2 billion cubic meters in the next seven days.

In response to the flood, the relevant departments combined various methods to prevent the fifth flood of the Yellow River. For example, flood interception and peak shaving, reservoir sediment discharge, river scouring and silting, and combined water and sediment regulation in the middle and lower reaches have been carried out. Since August 20th, the relevant departments have opened three dredging tunnels and a hollow slab, and dispatched generators to discharge them evenly at a speed of 4,000 cubic meters per second. It is estimated that the discharge process will not be less than 6 days.

Rational use of flood resources, officials of relevant departments said that during the flood season this year, there was a lot of water coming from the upper reaches of the Yellow River, and many reservoirs have been operating at a high water level. The relevant departments predict that there is a greater possibility of autumn rain in the Yellow River this year, and it is necessary to further prepare for flood control according to the overall demand. The flood discharge of Xiaolangdi Reservoir can be increased in time. This can not only prevent the water level in the reservoir area from rising too fast in the subsequent flood interception operation, but also make full use of the flood in the middle reaches to help the Xiaolangdi and Three Gorges reservoirs be washed away. At the same time, it also takes into account the safety of water resources in the lower reaches of the river, which can maximize the rational use of flood resources.

The staff of relevant departments also issued prevention and control notices in advance, strengthened organizational leadership, implemented flood control responsibilities, overcame fluky psychology, and strengthened the defense and inspection of the project. Do a good job in the corresponding safety management, but also send relevant personnel to assist in the ideological work of the masses to ensure flood control safety.
