Residents in lower reaches of Yangtze River should brace for evacuation: Chinese hydrologist

TAIPEI (Taiwan News) — As torrential rains in China continue to wreak havoc on more than 24 provinces, notable Chinese hydrologist Wang Weiluo (王維洛) has questioned the safety of the massive Three Gorges Dam, warning that it could collapse at any moment.

In southern China, regional rainstorms and mudslides that began on June 1 have uprooted more than 7,300 houses and affected nearly eight million people as of Monday morning (June 21). The immediate economic loss is estimated at 20.6 billion RMB (US$2.9 billion) by local officials.

The nonstop downpours have also raised the Chinese public's concerns over the potential bursting of the world's biggest hydropower project. Despite government assurances that the dam is structurally sound, Wang has taken an opposing view and claimed that the facility is not as stable as many have been led to believe, reported New Talk.

Wang pointed out that the dam's design, construction, and quality inspection were all carried out by the same group of people and that the project was finished too quickly. He said that even Chinese Vice Minister of Water Resources Ye Jianchun (葉建春) confessed at a June 10 press conference that water levels of at least 148 rivers in the country have risen above warning thresholds, which proves that the Three Gorges Dam has a limited effect on flood control.

Rather than commenting on the validity of the images showing the dam's warping a year ago, Wang said a more serious concern is the cracks and substandard concrete discovered during its construction. He said a failure of the dam would have catastrophic consequences for individuals residing in the lower reaches of the Yangtze River and that they should prepare for evacuation as soon as possible, reported CT Want.

In his interview with Radio France Internationale, the Chinese water expert also criticized the Chinese government and state media for refusing to acknowledge the potential danger of the reservoir. He said that scientists who have spoken the truth have been criminalized by Beijing, resulting in a society with no communication.

According to Chinese stated-owned CNTV, water inside the Three Gorges Dam continues to accumulate and has risen two meters above its flood-prevention level. Although the dam has been hailed by Beijing as one of the greatest engineering achievements in human history, its structural integrity continues to be questioned.

Chinese experts have dismissed rumors hyped by some Western media that the Three Gorges Dam, the world's biggest hydropower project, is at risk of collapse, noting the dam is intact and has spare capacity to hold the current inflows of water after southern parts of China experienced heavy rainfall and the Three Gorges reservoir's water level exceeded the flood control line.

Since China entered the flood season in June, southern and eastern regions of the country have experienced heavy and extensive rainfall. Floods have affected more than 2 million people and caused economic losses of billions of yuan.

The water level in China's massive Three Gorges Reservoir reached 147 meters on Saturday, two meters above the flood warning line. Meanwhile, the inflow increased to 26,500 cubic meters per second from 20,500 cubic meters per second on the previous day.

The alarming water level gave rise to rumors that the dam is under structural strain and nearby residents should evacuate. Some Western media hyped claims that the dam is at risk of collapse, which was not new in their discredit of the project.

Guo Xun, a research fellow at the Institute of Engineering Mechanics at the China Earthquake Administration in Beijing, refuted the rumors and speculation, saying that the dam is capable of holding far larger inflows than it is seeing now.

The dam is designed to meet "once-in-a-millennium" water level at 175 meters or flow up to 70,000 cubic meters per second. Currently, the 147-meter water level and 26,500 cubic meters per second levels are absolutely safe for the dam to bear, Guo told the Global Times on Monday.

There has been shoddy construction in China in the past but I honestly doubt the Three Gorges Dam is one of those. Should the dam collapse, hundreds of thousands if not more would instantly perish and the CCP would probably be overthrown if this happens. As such, I doubt they are careless with regards to this dam's safety.

There has been and always will be shoddy constructions everywhere in the world. But only in China a shoddy construction must have a deeper reason.

As for the stress the TGD is under right now, it is doing what it is supposed to do - alleviate flood. Without it an enormous area of the southern China would've already been flooded. Since it's completion the dam has prevented some major floods almost every year. And, on top of that, it generates "more than 18,000 MW of power per year. "That's more than eight times the capacity of the U.S.'s Hoover Dam and about three percent of China's energy needs." Don't take my words for it, see this fantastic article by this "free" press;) https://www.businessinsider.com/chi...am-is-turning-out-to-be-a-huge-mistake-2012-4

The collapse of such structure cannot happen overnight. It will start with cracks and the cracks will develop for years, even decades or centuries before the collapse.

In summary, this can only happen if the dam is totally neglected and not maintained for very long time, which is not the case.

Hi,

An infra structure can only stand against extremes of nature for so long---. Human engineering has limits against the onslaught of nature---.
