Will the flood of the Yellow River flood Zhengzhou City?

The flood of the Yellow River will not flood Zhengzhou City. On August 7, 2020, the reporter learned from the Yellow River Water Conservancy Commission of the Ministry of Water Resources that due to the recent rainfall, there was a peak flow of 5060 cubic meters per second at the Tongguan Hydrological Station of the Yellow River at 23: 54 on the 6 th, which was the third flood of the Yellow River in 2020. According to the weather forecast and the water conditions in the middle and lower reaches of the Yellow River, Sanmenxia Reservoir opened at 20: 00 on the 6th.

Xiaolangdi Reservoir stopped the flood at 20 o'clock on the 6th according to the outflow rate of 1000 cubic meters per second. In order to do a good job in this flood control work, the Yellow River Conservancy Commission has issued a notice to the Water Conservancy Departments of Shanxi, Shaanxi, Henan and Shandong provinces, requesting the relevant provinces (regions) and units to attach great importance to it and do their best to do a good job in flood control in the Xiaobei main stream of the Yellow River and Sanmenxia reservoir area and related flood control work downstream.

The relevant person in charge of the Yellow River Water Conservancy Commission said that an urgent notice had been sent to the water conservancy departments of the relevant provinces and regions in the basin, the western and northern war zones, and the water conservancy offices in the middle and upper reaches of the Yellow River, asking the water conservancy departments of Qinghai, Gansu, Ningxia, Inner Mongolia and other provinces to fully deploy the current flood control work and strengthen the observation of river regime and work conditions.

Strengthen dike inspection and engineering defense, report important floods and trends in a timely manner, and the hydrological department will also pay close attention to the weather situation and rain changes, and issue relevant forecasts and notifications in a timely manner.

Extended data:

On the morning of August 7, 2020, Yue, director of the Yellow River Conservancy Commission, presided over the Chamber of Commerce of the Flood Control and Drought Relief Association, analyzed and judged the current heavy rainfall process and the No.3 flood control work, and asked the relevant departments and units to make unremitting efforts to do all kinds of flood control work in detail to ensure flood control safety.

Since August 4th, there have been heavy rains in eastern Ningxia, northern and eastern Shaanxi and parts of central and western Shanxi, including Yan 'an, Yulin, Shangluo, Lvliang, Xinxiang and Kaifeng. The Wuding River, Qingjian River, Yanshui River, Sanchuan River, Quyi River and Weihe River in the middle reaches of the Yellow River have obvious flood processes.

Among them, the ultra-warning flood occurred in the upper reaches of Beiluo River, a tributary of Weihe River. At 0: 48 on the 6th, Longmen Hydrological Station, the main stream of the middle reaches of the Yellow River, had a flood peak flow of 4,330 cubic meters per second, and Tongguan Hydrological Station had a flow of 5,060 cubic meters per second at 23: 54 on the same day, forming the third flood of the Yellow River in 2020. During the meeting, the relevant flood control functional departments reported the development of flood control work No.3.

According to the actual rainfall in Luo Yi River and Dawen River since August 6th, the future rainfall and water regime trends in the upper reaches of the Yellow River, Luo Yi River Basin and Dawen River Basin are analyzed and predicted. Yue asked.

The first is to do a good job in flood control. At present, the Yellow River is still in the critical period of flood control, and the weather in the basin is complex and changeable. Heavy rainfall is frequent, and all levels and departments can't slack off. They still have to go all out to do all kinds of defense work carefully to ensure flood control safety.

The second is to scientifically dispatch reservoirs. Longyangxia and Liujiaxia reservoirs continue to operate according to the current dispatching mode. According to the upstream inflow situation, the consultation will be encrypted, and the reservoir dispatching process will be adjusted in a rolling way, so as to control the Longyangxia Reservoir not to exceed the design flood limit water level of 2,594 meters, and appropriately increase the discharge; Liujiaxia Reservoir continues to discharge at a flow rate of 2,300 cubic meters per second; Xiaolangdi reservoir was put into flood control operation, and the three sand discharge tunnels were kept fully open.

Third, we attach great importance to the flood control work of Dawen River. Send a joint working group to investigate the Dawen River basin project and river flow, check the progress of heavy rainfall prevention and flood control, and fully grasp the key reservoir projects and operation.

The fourth is to strengthen information reporting. Continue to submit the recent opinions on the rain, water regime and reservoir operation of the Yellow River to the Ministry of Water Resources to ensure that the information is uploaded and issued, and win the initiative for flood control work.

No.3 flood occurred in official website-Yellow River of Ministry of Water Resources in 2020, and the Yellow River Water Conservancy Commission held an encrypted consultation meeting.

Xinhuanet-No.2 flood occurred in the Yellow River in 2020.
