(May 1, 2008) There are different types of dams classified by the material and design used in construction. These differences influence how and why dams fail. A dam can be classified by its material, indicating whether it is earthen or concrete. Dam components can also include iron, steel or timber or a combination of any of the above.
(May 1, 2008) Overtopping occurs when the level of a reservoir exceeds the capacity or height of the dam. This can be caused by an inadequate or dysfunctional spillway or by settlement of the dam crest (for an explanation of settlement, see foundation defects).
(April 26, 2008) To apply INSAR observation technique to the Three Gorge Reservoir’s landslide monitoring, we’ve installed 10 corner reflectors on the landslide within Zigui county of the Three Gorge Reservoir area, meanwhile, set up GPS observation point, preliminarily forming GPS-CR landslide monitoring network. This paper of both INSAR observation technique and GPS observation technique in landslide monitoring researches.
(April 20, 2008) Emergency workers are still trying to rescue almost 200 people from a village that was nearly inundated by a massive landslide near the Three Gorges dam in central China on Saturday, the official Xinhua news agency reports.
(April 8, 2008) Fan Xiao, a geologist at the Bureau of Geological Exploration and Exploitation of Mineral Resources in Sichuan province, is quoted saying recent landslides in the Three Gorges area are directly linked to filling the reservoir. Water first seeps into the loose soil at the base of the area’s rocky cliffs, destabilizing the land and making it prone to slides.

(March 12, 2008) China’s State Environmental Protection Agency has urged citizens and corporations to take legal action if threatened by water pollution in the Three Gorges dam area.
(February 20, 2008) Chief engineer of the Three Gorges Reservoir Area Disaster Control Headquarters says the number of landslides and collapses in the dam’s reservoir area have nearly doubled between 2001 and 2003, reports Caijing magazine.
Canadian government responds to Probe’s recommendation that it must take responsibility for role in disastrous Three Gorges Dam
(February 6, 2008) In an open letter to Canadian officials, Probe International called for the government to make amends for failing to warn the Chinese government that the project’s environmental risks would ultimately threaten the lives, property, and economic future of millions of people living along the Yangtze river.
(January 23, 2008) China’s Three Gorges dam operator plans to fill the Three Gorges reservoir to capacity this year despite the risk of more landslides and worsening environmental problems along the Yangtze, the country’s most important river.
(December 29, 2007) Residents in the Three Gorges area are concerned by an increase in landslides as the water level rises in the 410 mile-long reservoir. “Almost all my fears have come true,” says Dai Qing. “The landslides and cracks have made people migrants once again."
(December 3, 2007) The death toll in the landslide in central China’s Hubei Province last month has risen to at least 34, after searchers pulled out one more body from the debris early on Monday. The landslide caused an avalanche of about 3,000 cubic meters of rubble that buried a nearby construction site and a bus travelling on State Highway 318, Xinhua reported.
(November 30, 2007) Chinese writer Dai Qing responds to the Chinese government’s campaign to downplay the environmental effects of the Three Gorges dam. “If they’re saying that the landslides have nothing to do with the reservoir than they are telling lies,” she told the BBC.
(November 27, 2007) Residents in the Three Gorges dam reservoir area fear an increased risk of harm to the environment as a result of the dam’s impacts. One of the biggest concerns currently is that the reservoir’s seasonal water fluctuations have unsettled the delicate geology of the area and that this may escalate the risk of landslides and other dangers.
(November 23, 2007) Chinese officials have confirmed that a bus carrying as many as 27 people has been discovered buried in a landslide that occurred earlier this week.
