10 Barragens mais Altas do Mundo (até 2013)

10 Tallest Dams in the World (until 2013)
This is a list of the tallest dams in the world. Currently, the tallest dam in the world is the Nurek Dam, an embankment dam in Tajikistan at 300 m (984 ft) high. The tallest arch dam is the recently completed 292 m (958 ft) high Xiaowan Dam in China. For gravity dams, the tallest is the 285 m (935 ft) high Grande Dixence Dam in Switzerland.
Note: Does not include natural dams.

Vajont disaster:

On 9 October 1963 at 10:39 pm, a massive landslide of about 260 million m3 of forest, earth, and rock, which fell from the mount Toc into the dam basin at up to 110 km per hour (68 mph) completely filled up the narrow reservoir in front of the dam. The landslide was much faster than predicted, taking just 45 seconds, and the resulting displacement of water caused 50 million m3 of water to overtop the dam in a 250-metre-high (820 ft) wave. The flooding from the huge wave in the Piave valley destroyed the villages of Longarone, Pirago, Rivalta, Villanova and Faè, killing around 2,000 people and turning the land below the dam into a flat plain of mud with an impact crater 60 metres deep and 80 wide. Many small villages near the landslide along the lakefront also suffered damage from a giant displacement wave. Villages in the territory of Erto e Casso and the village of Codissago (it), near Castellavazzo, were largely wrecked. Estimates of the dead range from 1,900 to 2,500 people, and about 350 families lost all members. Most of the survivors had lost relatives and friends along with their homes and belongings. The dam itself was largely undamaged — the top metre or so of masonry was washed away, but the basic structure remained intact and still exists today.
