12 Most Dangerous Dams In The WorldFeb 27, 2020
nature can be a very
dangerousthing with all the technology we have we are still powerless against nature there is very little we can do about earthquakes tornadoes and tsunamis even when we try to exert control over the water by building
damsthe results can be
dangerousas you are about to see in this video the kariba dam sits in a river basin where zimbabwe meets zambia it is a mighty concrete construction 420 feet high and nearly 2,000 feet long the creation of the dam was responsible of the formation of Lake Kariba, which covers an area of 170 miles, although the construction work of the dam began in 1955, it was not completely finished until 1977, by that time nearly 500 million dollars had been spent and 86 workers of construction had lost their lives gathering it 57,000 Tongan people had to be relocated so they were out of the way of redirected water and n 2014, the bedrock had been eroded by torrents of water and created a huge crater without urgent repair work it could fail completely putting three and a half million lives at risk today two
damsonly have twelve percent of its water capacity while repair work is carried out that renders the hydroelectric plant that depends on it al
mostinoperable. you can find the contra dam which is sometimes called the locarno dam in teeccino switzerland built in 1965 the dam created the vogue lake or know that the MW vers Aqsa hydroelectric power station relies on the dam to generate electricity unfortunately geologists had not realized the stress that filling the new reservoir would put on the ground beneath it when the reservoir filled it started a chain reaction of earthquakes that did not fully end until 1971 against the dam it is an impressive sight it has 720 feet high with a crest of 1,250 feet but also surprisingly narrow only 82 feet wide at the base despite the obvious danger a dam this size presents it has been used as a location for film crews James Bond jumped from the top in the opening scenes of 1995's Goldeneye has since been popular with bungee jumpers a hold that could fail as something scary the hold already failed is even worse it took less than 10 years of operation for the matchu to dam in India it burst and the results were catastrophic Matthieu 2 was completed in 1972 and was situated on the Mathieu river near the Raj code not even an unusually dam 20 feet wide at the top and 70 feet high, the Indians built it with a clay core and an earthen embankment that was ultimately not strong enough to deal with the torrents of water in August 1979 dam burst a wall of water cascading down the town of Moore tragically the incident caused many deaths official estimates of the number of people who lost their lives range from 1800 to 25,000 floods caused by sudden heavy rains simply put too much pressure on the dam and could not deal with the pressure since the disaster that the dam has had has been rebuilt, but now it has a spillway with a capacity of four ro times larger than the previous failed dam, since then fortunately there have been no further incidents.
The failure of the Machu dam raised questions about the safety and long-term viability of the Amalia Periyar dam, which is also in Bad India. The Periyar is an old dam that was completed in 1895 and shows signs of wear to add to the concerns as well. it is massive 176ft high and 1,200ft long twice in the last five years rain has seen the water level reached its maximum capacity of 142ft anything higher could lead to failure a study of the dam bad Periyar se carried out after the Machu disaster and concluded that an earthquake with a magnitude of 6 on the Richter scale or greater would destroy it the rubble stone masonry used in dam construction can now be focused on an outdated and unsafe method and there is evidence of pronounced leaks and seeps in 1979 the water level of the dam was temporarily lowered to 136 feet while repair work was carried out to strengthen it, but o It is now believed that the repair work could have damaged the masonry dam.
Failures are not just a fear of the past, they are a clear and present threat early this year. dam in Texas, USA failed was on May 21, 2019 when the spill gate failed causing an al
mostinstantaneous 12 foot drop in water level as the tides forced their way downstream the dam was approaching 100 years old and it was simply too eroded to continue being fit for life luckily there was no loss of life but the boats floating on the lake were destroyed when the lake effectively disappeared there was also a high mortality rate among wild fish and turtles Those who depended on the lake for survival died almost instantly repairing the dam.
It will likely take many years and cost around $30 million. Texas officials are now concerned about the state of several other dams in the nearby area, most of which are about the same age as the Lake Dunlap dam and were built the same way despite being recognized by the Guinness Book of World Records as one of the strongest dams in the
worldthe cyano soutien skaia and kokoschka dam russia has been beset by serious problems For several years the dam is really a huge power plant, the largest in the entire
worldcountry and was built in 1960. It is 794 feet high and 347 feet wide at the base.
The water pressure for the dam is an incredible 30 million tons. The first minor problem at the soutien skya dam occurred in 1979 when floodwater entered a turbine no one was harmed six years later a spring flood destroyed almost the entire bottom plate of the spillway ripped out the anchor bolts and left a scar of 21 feet into bedrock the spillway pit was caused by another flood three years later, in August 2009, the power plant's engine and turbine rooms flooded, causing two generators to explode underwater. 75 people were confirmed dead and th The resulting loss of power caused a major blackout throughout the area.
The accident also created an oil spill that released more than 40 tons of transformer oil downstream. It took five years for the dam to be fully operational again. The insurance was built in 1976 and was deemed by government officials to be a small structure with a low risk rating turned out to be anything but in January 2019 the dam almost completely collapsed releasing a flow of water and mud that passed through the offices of the mine that had been built around the dam one of the rooms that was destroyed by the mudflow was a cafeteria that was full of people because it was lunch time the wall of mud continued down the river breaking up inns farms and houses no one had time to react or get out of the way it is now known that at least 248 people lost their lives in the incident being called the Bruma Dino dam disaster local transportation links were washed away two rail bridges and 300 feet of rail were destroyed train tracks also attributed to the veil of the landslide the company that owns and operates the mine was held criminally responsible after from the collapse no concrete or metal was used to build the dam the walls were made of silt, sand and veil they had pushed the capacity to the limit which bears the name of a highly respected former president in the united states of america will not remain safe from damage harry s truman dam sites on truman lake missouri usa according to a specialist engineering report commissioned in 2018, it is currently considered unsafe.
The Army Corps of Engineers who studied the lake classified it as a class two hazard under their guidance, meaning the risk is very high and requires urgent action to avert a disaster. they have good reason to be concerned because there is a large population of people living downstream of the dam and the dam has shown that its ability to deal with high levels of stormwater is not great people living up to 60 miles of the dam would still be considered at risk in the event of a failure, generally speaking the dam can handle 660 feet of water if that number was over 700 the danger level would be extremely high the dam is just over 40 years old and is they have recommended repair work to prevent the possibility of something going wrong the creation of the banquet dam in china was an example of the chinese and soviet working together to create something the magnificent construction work began in 1951 and it was decided that the river ROO was the best place to build this new home for power generation and flood control.
Only a year later, the work was completed. The new dam was 80 feet high with a crest of over 300 feet. above sea level, given its size and the speed of the work, it may have been rushed. Cracks appeared in the clay construction within a year after it was completed when it flooded in 1975. It was the worst dam disaster in mankind. In the story, a typhoon dumped a year's rain on the dam in a single day and was unable to cope with more than 75 billion cubic feet of water that the dam released in less than six hours. A wave 23 feet high and six miles wide struck near Jingping Rounin Ping Yu and Ling Quan Big Soup Bad weather meant evacuation orders were not received Ill Millions of buildings collapsed and an estimated 250,000 people died although some believe that the figure was much higher it should be obvious that an earthen dam is not going to be as strong as a dam made of concrete or steel, so one may wonder why outdated earthen dams are not replaced as a matter of priority Teton Dam in Idaho USA it was an earthen dam and it's not there anymore it never really worked at all it collapsed when it was filling in June 1976 it was a powerful dam 305ft high 3100ft long 1700ft wide in the base open cracks were found during the construction phase but the builders believed incorrectly After they were able to resolve the crowding issues, they identified When a second problem occurred during the early stages of filling when groundwater was observed to flow 1000 times faster than anticipated, they continued to fill the dam despite the dam inevitably breaking at 9:30 AM. on saturday june 5 thirteen thousand head of cattle drowned in the surrounding area and eleven people lost their lives some by drowning some in the rush to escape there are three things that are generally responsible for the danger and disasters that occur at dams poor design maintenance poor or abnormal weather conditions when the Stava dam was promised to collapse in Italy in July 1985, it was all due to maintenance, there was nothing wrong with the way the dam was built and the weather conditions on the day of the collapse were normal , but basic maintenance had not occurred. has been done for years because the pipe used to drain the water from the upper dam was being crushed by the weight of the sediment above the drain therefore the age did not occur correctly and the water continued to be pumped as a consequence of the increase in the pressure of the water, the water soaked into the bank and eventually liquefied the ground, causing the upper dam to collapse into the lower dam, and then the lower dam to collapse In a domino effect, a wall of water tore into the village Stava at 60 miles per hour, bringing down 63 buildings and killing 268 people. 10 people involved in the operation of the dam were tried and convicted of gross negligence and involuntary manslaughter. it is dangerous simply because of where it is that is the case with the mussel dam in iraq the dam that opened in 1986 is 371 feet high and 2 miles long but only 33 feet wide at the top it was supposed to provide water and power for the area around it, but found itself at the center of several battles at one point during the 2003 Iraq war.
It was feared that soldiers had wired the dam to detonate and collapse the captured Allied mass. Although those fears proved unfounded in 2014 the dam was in the hands of Isis, although it was retaken by Allied forces after the infamous battle over the muscle dam, it was feared that the fighting had weakened the dam, which is already known to be undermining. weakening because of poor construction, it was tested by the US Army Corps of Engineers and described as the most dangerous dam in the world at risk of collapsing at any second if it were to collapse, both Mosul and Baghdad would be under water and millions of lives would be lost urgently the repair work has been ongoing since 2016 subscribe to the channel and turn on notifications and you will be the first to know when a new video is out thanks for watching and see you in the next video
