Friends, why are dams built, the main reason behind building dams is to facilitate people and increase the progress of the place, but what if this dam becomes a threat to people, today we will tell about five dam failures of the world.
No.5 Failure Of Malpasset Arch Dam
This was the first time in the history of the world that an arch dam broke so badly that the Melpesset Dam of France, today this accident is seen as a case study of dam construction so that such a mistake is not repeated again in the future of the dam on 2 December 1959. The water entered the valley breaking the dam, causing a lot of damage to life and property in the surrounding areas. Not only this, about 400 people died in this flood, there were many reasons for the collapse of the dam, the negligence of the authority, poor management and a bad sleep which made it the century. Made the biggest industrial dam failure
No.4 South Fork Dam Failure
South Folk Dam was constructed over artificially made Lake Connemkh, it was constructed between 1838 and 1853 for public works in Pennsylvania, United States, although it could not last long to do its work, continuously on 13 May 1889. Due to heavy rains, the dam could not withstand the rain water and on 31 May 1889, 20 billion tons of water came out breaking the dam as a flood, this terrible accident took more than two thousand people inside itself and many areas were destroyed. Of these, the city of Johnstown was one of the most affected areas, due to which the accident is also called the Johnstown flood disaster, due to the dam fair, the reconstruction done in it was actually done in the old structure of the dam in the last few years. Changes were introduced due to which the capacity of the dam decreased and could not bear the brunt of heavy rains.
No.3 Vajot Dam Landslide
This dam, made of technical features, became a lesson for engineering for the coming generation, in fact, the Waijon dam was built at a place where landslides used to happen, the engineers who built it did not make any mistake in its design, but the same geological factor. After the construction of the dam by June 1960, minor landslides were reported and on 9 October 1963, a huge 7,000,000 cubic meter stone broke from the Maunkdok and fell directly into the reservoir of the dam, causing a fierce 50 cubic meter wave. It arose and destroyed many villages present in the valley as well as killed about 2000 people Even though the dam was the largest and modern dam at that time, it will still be called a carelessly built project which destroyed the lives of many innocent people.
No.2 Machhu Dam Disaster
This unfortunate dam accident that happened on August 11, 1979 fills the mind of the people of Gujarat with terror. Machu Dam was built in the year 1972 under the Irrigation Project, but the irregular and incessant rains made this dam 4 km long. The water broke from the dam had increased 3 times more than the capacity of the dam, due to the overloading, the walls were broken and within 20 minutes the water level reached from 12 feet to 30 feet, this flood settled 5 kilometers below the dam, Morbi city After about a week, the water level decreased slightly, although by then the city of Morbi was completely destroyed. Carcasses of animals were floating around, pieces of human body were floating in Morbi besides thousands of lakhs and broken houses. There was nothing left to see, it is estimated that at this time about 18 to 25000 people were killed in the accident.
No.1 Banqio Dam failure
More than two lakh people were killed in China's Bankiaw Dam, it was the third largest flood in history, which would be more correct to say human negligence rather than a natural disaster. The Bankiaw Dam was built from the perspective of flood prevention and electricity generation But its structure was not able to take much load. On the night of 8 August 1975, at 1:00 pm, the Benqiao Dam started to collapse and in no time a 33 feet high water wave started moving towards a city in China at a speed of 50 km. All 9600 people living were killed and 62 dams broke on the same day, no prior warning was given by the Chinese government, as a result 26000 people drowned in this dam and about 145000 people died, the Chinese government tried to hide this accident a lot. But according to some figures, the level of death was more than 220,000 and about 10 billion people were affected by it.
