Top 5 Highest Dams in the World

Here’s the list of highest dams in the world. Dam is a construction that built to withstand the rate of water in the river into reservoirs that can be called artificial lakes and become a place of recreation. Often dams are also used to drain water into a hydroelectric power generation. Most of the dam also has a section called the gate to remove unwanted water continuously or gradually.

While dam have lot of benefit, we have to make sure that the dam is strong enough so that it won’t broke. As if the dam is broken it will cause large flood. This will make the people have to repair their house and do water damage cleanup as well as flooded basement cleanup when they have some basement on their house. For the purpose of strong construction these highest dam are made. So, let’s take a look at those highest dams in the world.

4. Vajont Dam, Italy: 262 meters

One of the highest 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 seiche wave that brought massive flooding and destruction to the Piave valley below, wiping out several villages completely.
