Water resources expert: Ethiopia's dam collapse is 50% possible

[The SC]

April 12, 2021

Dr. Abbas Shraky, a professor of water resources at Cairo University, said that it is possible to see the Renaissance Dam collapse by 50%, as many of its counterparts in Africa have experienced in recent years.

Abbas Sharaki added, during a television interview, that there are a number of dams that had been built in the African continent during the past years, which had collapsed due to natural hazards, stressing that the company implementing the Ethiopian Renaissance Dam had previously built a number of dams that had collapsed.

Shraki explained that Ethiopia has the largest fault line extending to Turkey, this fault line caused Ethiopia to be in two halves, and that is why the land is very low and there are active volcanoes, pointing out that the most earthquake-prone areas in Africa are concentrated in the eastern region towards Ethiopia. The presence of faults, canyons and volcanic mountains with the rain that fall heavily on it in a short period of time in addition to the presence of earthquakes.

Shraki said that Ethiopia had built a dam without comprehensive and complete engineering studies, stressing that in the event of the dam collapsing, Ethiopia would only lose the money it spent, but it would affect the surrounding countries, especially Sudan.

He stressed that there is no guarantee that the Ethiopian dam will remain for long periods due to nature, stressing: "Nature is stronger than us."

Shraki also compared the area on which the High Dam was built in Egypt, with its counterpart in Ethiopia, explaining that Egypt does not have faults or volcanic mountains and is not threatened by earthquakes.

He stressed: "When the gates of the Ethiopian dam have been opened it has caused floods in Sudan, and we can face nature with its strength in the Ethiopian plateau, and the Ethiopian people will not benefit from this dam because they live above in the mountains higher from the level of the dam by two thousand meters, and Ethiopia does not have a network of internal electricity, but it aims to sell it only. Ethiopia’s constant talk of its people benefiting from the construction of the dam is only to gain the sympathy of the world."

BS talks
we are sitting on fault line with mega earthquakes and we have world #1 largest dam since 1976 and world 6th largest dam since 1967 . dam will not go anywhere rather then dreaming egypt solve the issue .

Tarbela Dam (Pakistan)
Generates 5000 MW

Visit the Tarbela Dam for See It in Action

As the largest earth-filled dam in the world, Tarbela Dam holds a prized position among the dams in Pakistan. Located in the Haripur and Swabi districts in KPK, the dam was built to control the flow of the River Indus, resulting in the reservoir known as Tarbela Lake. While the project began in the early 1960s, construction of the dam progressed in the three stages, being completed in 1976. However, the Tarbela Dam continues to undergo extensions and refurbishment as required, because it is Pakistan’s primary source of hydropower electricity.

you missunderstood my post sir tarbela dam is world #1 by structural points and yet its next to major fault line . we having massive earthquakes and nothing happen to our dams nuclear plants etc . this dam is not going anywhere by natural forces . egypt have to act or solve on table rest are just feel good articles .

I did understand you sir..I said Ethiopia has very heavy rains that adds to the problem..
Egypt was trying to solve the issue with Ethiopia for the last decade exactly 10 years of negotiations now..so the ball is in Ethiopia's court..

nothing is wrong with more rains dams have spellways for exact same porpuse releasing of water . a big dam like this will not fill with sand next 50 years too . so no hope from nature . if egypt willing to take it then they should try . but since last inverview of sisi it seems he is saint and he have no plan for using military .

True as 90% of the issues are solved , the problem remaining is 10%..hopefully it will be solved soon..and everyone will be happy in the region..

Pakistan is endowed with breathtaking landscapes, magnificent deserts, and a plethora of natural resources. Pakistan is mostly an agricultural country that relies significantly on water resources for agriculture. Surprisingly, Pakistan has over 150 dams spanning all regions, but we have compiled a list of most famous dams in Pakistan. These large dams not only provide energy and water, but they also serve as ideal holiday locations for people. The majority of dams were built between 1960 and 1975. Pakistan is fortunate to be the owner of the world’s largest earth-filled dam, the Tarbela dam.

What will happen if the Renaissance Dam collapses when it is completely full: an Egyptian expert

The Egyptian expert Rashad Hamed published a summary of research published in a scientific journal on the damage that could be caused by the collapse of the Renaissance Dam while it is completely full.

• After the start of the main dam's collapse, the water will flow and gradually increase its speed until it reaches a constant rate of 2 million cubic meters per second 5 hours after the start of the collapse.

• Water will reach the Roseiros Dam 6 hours after the start of the main dam collapse.

• After 11 hours from the beginning of the collapse, 99.5% of the water retained in the Renaissance Dam has reached the Roseiros Dam.

• The area between the Renaissance Dam and the Roseiros Dam will turn into a lake as the picture below shows. The largest lake depth at the Renaissance Dam will be 101 meters, the largest depth is 55 meters at the Roseiros Dam, the maximum width is 30 km, and the speed is 25 meters per second at the Renaissance Dam and decreases to 10 meters In the second at the roses.

• The peak of water reaching Khartoum occurs after 134 hours (five and a half days) and reaches a maximum depth of 21 meters. Khartoum and all the surrounding areas will turn into a lake as in the third picture, the maximum width of the water is 176 km, and the speed is 8 meters per second.

• The water will reach the entrance to Lake Nasser after 549 hours (approximately 23 days), which is a period sufficient to take the necessary measures to absorb the water coming into the lake. The width of the water wave will be 27 km, and the water speed is 14 meters per second, 6 meters per second more than its speed at Khartoum due to an increase in Downstream Nile.

In summary, this means that Egypt is completely safe in the event of the dam’s collapse, because the amount that reaches Lake Nasser is 15 billion cubic meters, and it arrives after 23 days, this period of time is sufficient to empty space in the dam’s lake to accommodate the incoming water, if there is not an empty space already..
