Top 10 Tallest Dams in the World
The tallest dam in the world is the Nurek in Tajikistan at 300 meters.The list of top ten are given below.
1. Nurek Dam, Tajikistan – 300m
2. Grande Dixence Dam, Switzerland – 285m
3. Inguri Dam, Georgia – 271.5m
4. Vajont Dam, Italy – 261.6m
One of the tallest dams in the world, it is 262 metres (860 ft) high, 27 metres (89 ft) thick at the base and 3.4 metres (11 ft) at the top. Its 1963 over-topping was caused when the designers ignored the geological instability of Monte Toc on the southern side of the basin. Warning signs and negative appraisals during the early stages of filling were disregarded, and the attempt to complete the filling led to a landslide which created a wave that brought massive flooding and destruction to the Piave valley below, wiping out several villages completely.
On 12 February 2008, while launching the International Year of Planet Earth, UNESCO cited the Vajont Dam tragedy as one of five "cautionary tales", caused by "the failure of engineers and geologists."
