Floods In China


China sees heavy rainfall every year which leads to floods.


People in China are suffering alot they are loosing their property and loosing thier family. There is water all over the country.. Heavy rainfall and floods causing lot of destruction all over the country.
Horrifying visuals of overturned cars and people trapped in flooded subways and streets of China have inundated social media in the past three days. A video by the China Xinhua News shows commuters in neck-deep water inside a metro line at the Zhengzhou city, which has a population of over 1.2 crore citizens, as they wait for rescuers to arrive. Not just subways, streets, hotels, and a large number of buildings were waterlogged, bringing the city’s public transport to a halt. The Shaolin Temple, a sanctuary for Buddhist monks, has also been reportedly hit by severe floods.

the rainfall has made the flood control situation very severe, with water levels in alarming levels in rivers and damages to dams. While sections of railways have been suspended, several flights have also been cancelled.

The downpour has led to the breach of several dams. Local authorities in the Luoyang city reported a 20-metre breach in the Yihetan dam, fearing it could collapse any time, the military blasted the dam to release the floodwaters. In Zhengzhou, the Guojiazui reservoir has been breached but there have been no reports of a dam failure yet.

The president ordered all authorities to organise flood relief forces and highlighted the need to minimise casualties as well as take care of hygiene and disease control to prevent epidemics.
Zhengzhou city sits on the banks of the Yellow River, the second longest river in China, which is another reason why it’s harder to control floods in the area. The country has relied on man-made dams and reservoirs to mitigate flooding, but with extreme rainfall, the dams are unable to hold water. Officials in the past have also raised concerns over the strength of the Three Gorges Dam, the world’s biggest hydroelectric station, built on the Yangtze River, as rainfalls get heavier over the years. China have created dams to prevent floods there are Multiple dams in the Yangtze river basine which control floodwaters; the biggest and most important of these is the Three Gorges Dam with its largest area of about 1,000,000-square-kilometre (390,000 sq mi). It was constructed not only for power generation but also for flood control.By the end of June, the dam had started to release floodwaters. While the CMA indicated flood discharge started on 29 June, satellite images suggest that floodgates were opened already five days earlier.Yichang, a city below the dam, experienced extensive flooding, raising questions about the effectiveness of the flood control by the dam.According to the company that manages the dam, the dam had been “effectively reducing the speed and extent of water level rises on the middle and lower reaches of the city”.Critics, however, suggest that the dam is “not doing what it is designed for” and unable to deal with severe events.Other experts have pointed out that studies do show that the dam does help alleviate typical flooding during normal years and that the problem is not the design of the dam, but the public’s expectation that the dam alone can solve all the problems of flooding on the Yangtze. Particularly, when significant amounts of rainfall occurred downstream of the Three Gorges Dam in the middle and lower reaches of the Yangtze which will never pass through the dam. three flood waves from rains in the upper Yangtze basin arrived at the dam, necessitating the opening of sluice gates multiple times to create space in the reservoir.In Chinese social media it was claimed that this exacerbated downstream flooding, while the dam operators maintained that the action helped to delay floodwaters going downstream.On 15 August, “Flood #4” passed through the Three Gorges reservoir with a maximum inflow of 62,000 cubic meters per second, the highest reached at that time during this flood season
