12 Most Dangerous Dams In The World

Nature can be a very

dangerous

thing with all the technology we have, we are still practically powerless against nature, there is very little we can do about earthquakes, tornadoes and tsunamis, even when we try to exert our control over water by building

dams

. It can be

dangerous

, as you are about to see in this video, the Kariba Dam is located in a river basin where Zimbabwe meets Zambia. It is a powerful concrete construction that measures 420 feet high and reaches al

most

2,000 feet long. The creation of the dam was responsible for the formation of Lake Kariba, which covers an area of ​​170 miles, although construction work on the dam began in 1955, it was not fully completed until 1977, by which time al

most

500 had been spent million dollars and 86 construction workers had lost their lives during construction. 57,000 Tongans had to be relocated so they were out of the way of the diverted water.

By 2014, the bedrock had been eroded by torrents of water, creating a huge crater. Without urgent repair work, it could fail completely, taking three and a half million lives. There are currently two

dams

at risk that only hold twelve percent of their water capacity while repair work is carried out, making the hydroelectric power station that depends on it almost inoperable. In Teeccino, Switzerland, is the Contra Dam, sometimes called the Locarno Dam. Built in 1965, the dam created Lake Vogue or meet the MW vers Aqsa hydroelectric power station relies on the dam to generate electricity, unfortunately geologists had not realized how much stress filling the new reservoir would put on the ground beneath it as the tank was filled.

It started a chain reaction of earthquakes that didn't fully end until 1971. The contra dam is an impressive sight: it's 720 feet high with a 1,250-foot crest but it's also surprisingly narrow, just 82 feet wide at the base. despite the obvious danger that a dam of this size represents. presents has been used as a location for movie film crews James Bond jumped from a height in the opening scenes of 1995's Goldeneye has since been popular with bungee jumpers a dam that could potentially fail as a scary thing the dam that has already failed Even worse, it took less than 10 years of operation for the matchu dam in India to burst and the results were catastrophic.

Matthieu 2 was completed in 1972 and was situated on the Mathieu River near the Code Raj, it was not even an unusually large dam. Measuring 20 feet wide at the top and 70 feet high, the Indians built it with a clay core and an earthen embankment that ultimately were not strong enough to withstand the torrents of water. In August 1979, the dam burst and a wall of water cascaded over the town of Moore, tragically the incident caused many deaths. Official estimates of the number of people who lost their lives range between 1,800 and 25,000. The flooding caused by sudden heavy rains simply put too much pressure on the dam and it could not withstand the pressure.

Since that disaster the dam has been rebuilt but now has a spillway with a capacity four times the capacity of the previous failed dam since then fortunately there has been no more incidents the failure of the Machu dam raised questions about the safety and long-term viability of the dam The Amalia Periyar Dam, which is also located in India's Mala Periyar, is an old dam that was completed in 1895 and shows signs of wear to increase worries. It's also huge, 176 feet high and 1,200 feet long, twice in the last five years. Since the water level reached its maximum capacity of 142 feet, anything higher could cause a failure.

A study of the Mala Periyar Dam was carried out after the Machu disaster and it was concluded that an earthquake with a magnitude of 6 on the Richter scale or higher would destroy it. The stone masonry used in the construction of the dam is now an outdated and unsafe method and there is evidence of pronounced leaks and seepage. In 1979, the dam's water level was temporarily lowered to 136 feet while repair work was carried out to strengthen it, but it is now believed that the repair work may have damaged the masonry dam's failures are not just a fear of the past, are a clear and present threat earlier this year the Lake Dunlap dam in Texas, USA, failed it was on May 21, 2019 when the spill occurred The gate failed, causing a fall almost instantaneous 12 feet in water level as the tides advanced downstream.

The dam was approaching 100 years old and had simply eroded too much to remain fit for purpose; Fortunately, there was no loss of human life, but there was loss of boats that were The floats on the lake were destroyed when the lake effectively disappeared, there was also a high mortality rate among the wildlife, fish and turtles that depended on the lake for survive they died almost instantly. Repairing the dam will likely take many years and cost somewhere in the region. of $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 in the same way despite Having been recognized by the Guinness Book of World Records as one of the strongest dams in the

world

, the Cyano Soutien Skaia and Kokoschka Dam, Russia has been beset by serious problems for several years.

The dam is actually a huge power plant, the largest in the entire country 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 flood water entered a turbine. No one was injured. Six years later, a spring flood destroyed almost all of the spillway's bottom plate, tearing out anchor bolts and carving out a hole. 21-foot scar in the bedrock, the spillway shaft suffered another flood three years later, in August 2009, the power plant's engine and turbine rooms were flooded, causing two generators to explode underwater. 75 people were confirmed dead and the resulting loss of power caused a major blackout across the area.

The accident also generated 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 in the loading day phase. Our dam in Brazil was supposed to be safe, it was built in 1976 and was considered a small structure with a low risk rating by government officials. It turned out to be anything, but in January 2019 the dam almost completely collapsed releasing a flood of water. and mud that swept away the mine offices that had been built around the dam. One of the rooms that was destroyed by the mud flow was a cafeteria that had been crowded with people because it was lunch time.

The wall of mud was still flowing. down breaking In the inns, farms and houses no one had time to react or move away, it is now known that at least 248 people lost their lives in the incident that is known as the Bruma Dino dam disaster. Local transport links were wiped out with the destruction of two railway bridges and 300 feet of railway tracks also attributed to the landslide. The company that owned and operated the mine was held criminally liable after the collapse no concrete or metal was used to building the dam the walls were made of silt and sand and the veil had taken the capacity to the limit bearing the name of a highly respected former president in the United States of America will not keep the Harry's Dam sites one bit safe from damage Truman Lake Truman in Missouri, USA, according to a specialized engineering report commissioned in 2018, is currently considered unsafe, the Army Corps of Engineers who studied the lake classified it as a class two hazard according to their guidelines, which means that the risk is very high and requires urgent measures to avoid a disaster.

They have good reason to be worried. 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 rainwater is not very good. People living up to 60 miles away from 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 exceeds 700, the danger level would be extremely high. The dam is just over 40 years old and repair work has been recommended to prevent the possibility of anything leaking. Wrong, the creation of the Banquet Dam in China was an example of how the Chinese and the Soviets worked together to create something magnificent.

Construction work began in 1951 when it was decided that the ROO River was the best place to build this new home of power generation and flood control. Just one year later the work was completed, the new dam was 80 feet high with a crest that was 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 a year after its construction. It was completed when it flooded in 1975. It was the worst dam disaster in human history. A typhoon dropped a year's worth of rain on the dam in a single day and it could not cope with more than 75 billion feet. cubic of water were released by the dam in In less than six hours, a wave 23 feet high and six miles wide hit near Soup Big Jingping Rounin Ping Yu and Ling Quan.

Bad weather meant no evacuation orders had been received. Millions of buildings collapsed and approximately 250,000 people died, although some believe the number. 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. The Teton Dam in Idaho, USA, was an earthen dam and is no longer there, it never worked at all, it collapsed while it was being filled in June 1976. It was a powerful dam 305 feet high, 3100 feet long and 1,700 feet wide at the base with open fissures. were encountered during the construction phase, but the builders incorrectly believed they could solve the overcrowding problems.

A second problem was identified during the early stages of filling when it was observed that groundwater was flowing 1,000 times faster than anticipated, they continued to fill the dam. Despite everything, inevitably the dam broke at 9:30 a.m. On Saturday, June 5, thirteen thousand head of cattle in the surrounding area were drowned and eleven people lost their lives, some drowned and others in the rush to escape, there are three things that are generally responsible for the danger. and dam disasters poor design poor maintenance or abnormal weather conditions when they promised the stava dam collapsed in italy in july 1985 it was all due to maintenance there had been nothing wrong with the way the dam was built or the Weather conditions on the day of the collapse were normal, but basic maintenance tasks had not been performed for years as a result of the pipe used to drain water from the upper dam being crushed by the weight of the sediment above it, so that the drainage did not occur properly and the water continued to be pumped as a result of the increased water pressure is that the water soaked the bank and eventually liquefied the soil, causing the upper dam to collapse onto the lower dam and then the dam lower collapse in a domino effect, a wall of water then broke in the town of 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 negligence serious and homicide sometimes a dam is dangerous simply because of its location, that is the case of 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 surrounding area, but found itself at the heart of several battles. At one point during the 2003 Iraq War, it was feared that soldiers had wired the dam to detonate and collapse muscle captured by Allied forces, although those fears proved unfounded. In 2014, the dam was in the hands of Isis, although the Allied forces recovered it. After the infamous battle over the muscle dam, it was feared that the fighting had weakened the dam, which is already known to be weakening due to poor construction. The US Army Corps of Engineers tested it and described it as the most dangerous dam at risk in the

world

. collapse at any second if it were to collapse, both Mosul and Baghdad would beunderwater and millions of lives would be lost.

Urgent repair work has been carried out since 2016. Subscribe to the channel and turn on notifications and you will be the first to know when a collapse will occur. A new video is out, thanks for watching and see you in the next video
