Will Tongguan Station have the biggest flood since 1996?

That's right. On August 20th, according to the news of the Yellow River Conservancy Committee of China Ministry of Water Resources (hereinafter referred to as the Yellow River Conservancy Committee), the hydrological department predicted that the continuously evolving No.5 flood of the Yellow River would reach 6,600 cubic meters per second at Tongguan Hydrological Station on August 2nd/day 10, the largest flood since this station 196.

Combined with the flood situation in the upper, middle and lower reaches of the Yellow River, the Yellow River Commission implemented the joint operation of water and sediment in the middle and lower reaches of the Yellow River on August 20 12, Sanmenxia Reservoir continued to open floodgates to discharge water, Xiaolangdi Reservoir opened three silt-discharging tunnels and 1 orifices, and the units generated electricity and discharged water, and simultaneously started the Class IV emergency response for flood control and drought relief in the middle and lower reaches of the Yellow River.

Extended data:

Experts from the Yellow River Water Conservancy Commission of the Ministry of Water Resources told reporters:

During the flood season this year, there was obviously more water coming from the upper reaches of the Yellow River, and Longyangxia and Liujiaxia reservoirs have been running at high water levels. In addition, there is a greater possibility of autumn rain in West China in the Yellow River basin this year. Therefore, it is necessary to increase the discharge of Xiaolangdi Reservoir in time to plan the overall flood control needs in advance.

This can not only prevent the water level in the reservoir area from rising too fast in the subsequent flood interception process, but also make full use of the flood process of the main tributaries in the middle reaches to further scour the siltation of Xiaolangdi and Sanmenxia reservoirs, promote the inter-annual adjustment of sediment in the reservoir channels, take into account the shaping adjustment of the downstream channels and the safety of water resources, and maximize the use of flood resources.

The Yellow River Conservancy Commission of the Ministry of Water Resources also issued a notice to the relevant river affairs departments and local flood control departments, demanding to strengthen organizational leadership, compact flood control responsibilities, overcome paralysis and luck, strengthen dike inspection and engineering defense, do a good job in wading safety management in low beach areas and pontoons, and send a working group to the downstream flood control line to ensure flood control safety.

Public trust. Com- Yellow River Conservancy Commission: Tongguan Station will have the biggest flood since 1996.
