Everything Everywhere Daily: History, Science, Geography & More - The Aswan High Dam

Starting point is 00:00:00 In 1970, one of the world's largest infrastructure projects opened in Aswan, Egypt. It was a dam that harnessed the power of the Nile River, the longest river in the world. The dam provided electricity for almost half the country and tamed the annual floods which were a regular feature on the Nile River. But the project wasn't without its drawbacks. It became a point of contention during the Cold War, displaced thousands of people, and destroyed an unknown number of ancient Egyptian artifacts.

Starting point is 00:00:58 It effectively turned day into night. And how it shaped the world now. Time travel with us every week on the ThruLine podcast from NPR. Damning the Nile River is an idea that's been around for almost a thousand years. In the early 11th century, the engineer Ibn El Hitham was summoned by the Fatmid Caliph to Cairo to see if he could do something about the flooding in the Nile. He investigated the problem, realized that a dam across the Nile was the only solution, and also realized that it was impossible given the state of technology at the time.

Starting point is 00:01:37 And here's a good time as any to explain the flooding of the Nile and how it was both a blessing and a curse to the Egyptians. If you know anything about ancient Egypt, you probably know that the reason why it was able to flourish is because the banks of the Nile were extremely fertile. The reason for this had to do with the flooding of the Nile River. When it did flood, it would deposit nutrient-wrench soil along the Nile's floodplain. This is what made the land extremely fertile

Starting point is 00:02:05 and supported one of the world's earliest and most successful agricultural civilizations. However, as Egypt modernized and its population grew, the very floods that sustained life for thousands of years also became increasingly problematic. The problem was with the unpredictability of the floods. In some years, the floodwaters were too high, submerging entire villages, destroying crops, and causing widespread devastation. In other years, the floods were too weak, leading to drought, water shortages, and sometimes famine. The ancient Egyptians had adapted to this cycle, but in the model,

Starting point is 00:02:41 In modern era, such instability threatened economic development, food security, and infrastructure. With the expansion of agriculture beyond the traditional floodplain, year-round irrigation became necessary. The reliance on seasonal flooding meant that farmers could only now cultivate their crops during certain times of the year. If the floods were controlled, irrigation could be regulated, allowing multiple growing seasons and increased food production. Urbanization and industrialization also made flood control essential. As Egypt developed, cities, roads, and industries were built near the river. Unchecked floods posed a major threat to this infrastructure, and controlling the river became necessary to prevent economic and human losses.

Starting point is 00:03:25 The next serious consideration of placing a dam on the Nile took place in the 19th century. Mohamed Ali Pasha, the Ottoman Viceroy of Egypt, ruled from 1805 to 1848, is considered to be the founder of modern Egypt. During his reign, the idea of controlling the Nile floods came up, but nothing concrete was ever done or even proposed. One of the first actual proposals for a dam came during the reign of Kedive Ishmael Pasha in the mid-19th century. He sought to transform Egypt's agricultural economy by expanding irrigation, particularly for cotton production, which had become a crucial cash crop. European engineers, particularly British and French experts were consulted to explore ways to regulate the river's flow. However, no major projects

Starting point is 00:04:10 materialized at the time due to technical limitations and financial constraints. In 1882, the British occupied Egypt as part of its efforts to control the Suez Canal. In the 1890s, the British administration, led by Lord Cromer, commissioned plans to construct a dam to improve irrigation and prevent seasonal flooding. This resulted in the construction of the Aswan Low Dam, completed in 1902, just outside the city of Aswan. If you've ever wondered if the Aswan High Dam meant that there was a low dam, the answer is yes. Designed by Sir William Wilcox, the dam was initially effective in controlling water levels, but was soon found to be inadequate as Egyptian agriculture expanded. There were a few problems with the low dam.

Starting point is 00:04:57 First, it wasn't built high enough because the British wish to protect Egyptian ruins, particularly the Temple of Filae, which was one of the best preserved Egyptian temples in the Upper Nile. The Filei Temple is on an island upstream from the low dam, and if the dam were bigger, then the temple would have been submerged. The second problem was that the dam wasn't built to generate electricity. Although generators were eventually added in the 1930s, the size of the dam limited the amount of electricity, that could be produced. Even before the Aswan low dam was completed, discussions about building an even larger dam were already underway. Some early proposals envisioned a more ambitious

Starting point is 00:05:37 structure further upstream to store a greater volume of water. However, the technology and engineering expertise required for such a massive project were not yet advanced enough. Ideas and plans were discussed for several decades. In 1952, a Greek-Egyptian engineer named Adrian Danios came up with a plan for an upper dam that would have its reservoir in Sudan and Ethiopia. However, the leader of Egypt at the time, King Farouk, had no interest in the project. But later that year, King Farouk was overthrown in a military coup, and the Egyptian position on a new dam was completely reversed. In 1954, a new president came to power, Gamal Abdel Nasser. Nassar wasn't just the president of Egypt. He claimed,

Starting point is 00:06:25 to be the leader of Arab nationalism across the region and supported the overthrow of all Arab monarchies. Nassar supported the construction of a new dam, which was now very much possible given the state-of-the-art dam construction. He wanted to modernize Egypt, and the creation of a new dam would radically jumpstart that by providing electricity for half the country. The United States was concerned that the Arab nationalist movement could easily find its way to the support of the Soviets, so they and the British offered to fund the construction of the dam by offering a loan to Egypt. Nassar was very much a nationalist and willing to play the Americans and Soviets against each other. However, in 1956, when Egypt seized the British-controlled Suez Canal, Western support suddenly dried up.

Starting point is 00:07:11 And this left Nassar to accept support from the Soviet Union. The cost of the dam was approximately a billion U.S. dollars, a massive sum for Egypt at the time when a billion dollars was a lot of money. Soviet loans and assistance made the project possible, deepening Egypt's ties to the Eastern Bloc during the Cold War. The dam that was going to be built would have most of its reservoir water stored in Egypt now, not Sudan, as the 1952 proposed dam would have done. This was primarily for geopolitical reasons. The Soviets agreed to support the dam in 1958 and plans went ahead. Construction of the new dam began in 1960, and the dams, and the dam was to be an earthen dam. Tens of thousands of workers were involved in the project, all working

Starting point is 00:07:58 under harsh desert conditions. Immediately as construction began, archaeologists and Egyptologists noticed a serious problem. The reservoir behind the dam would completely submerge the temple of Abu Symbol. Abu Symbol, one of Egypt's most iconic ancient temple complexes, was an extraordinary feat of engineering built by the Faro Ramsey II in the 13th. 13th century BC. You may have seen photos of it. It has several enormous reliefs of Ramsey's 2nd carved in stone in the front. To prevent this cultural loss, UNESCO launched an ambitious campaign in 1960 to save Abu Symbol. The solution involved cutting and relocating the entire temple to higher ground. Over the course of four years, from 1964 to 1968, a team of

Starting point is 00:08:48 engineers and archaeologists carefully sawed the temple into massive blocks, each weighing between 20 and 30 tons. These blocks were then meticulously labeled, moved to a prepared site 65 meters higher and 200 meters back from their original location, and reassembled with precision to maintain their original orientation and alignment. To replicate the original setting, engineers constructed an artificial mountain to house the temples, preserving their grandeur, and ensuring that the famous solar alignment, where the sun illuminates the inner sanctum on specific days, remained intact. The project, costing around $40 million, was a milestone in heritage preservation and set a precedent for saving endangered archaeological sites worldwide. There were almost certainly undiscovered and unknown artifacts buried along the banks of the Nile that were destroyed as the reservoir was filled with water.

Starting point is 00:09:45 The other major problem in building the dam was that people lived along the banks of the Nile River in southern Egypt. Approximately 100,000 people of the Nubian ethnic group lived along the Nile and were forcibly relocated to a higher elevation. They had lived along the banks of the Nile for thousands of years, maintaining a distinct language, traditions, and way of life. Most of them were moved to an area called New Nubia near Kaumbo about 50 kilometers north of Aswan. While the government constructed houses and infrastructure for them, the resettlement sites were drastically different from their original homeland. The fertile river banks and lush landscapes that they had relied on for farming and fishing were replaced by a dry, arid landscape,

Starting point is 00:10:32 making traditional agriculture much more difficult. With Abu Symbol moved and the Nubian people relocated, the dam was finished in 1970, and the dam was finished in 1970, and the city, and the city, and the and the process of filling up the reservoir, now known as Lake Nassar, began. You can't just shut off the entire river to fill up the reservoir, however. You have to continue to let some water pass while keeping some water to fill up the reservoir. The dam is 3,830 meters long, 980 meters wide at its base, and 111 meters high, requiring enormous amounts of material. Over 34 million cubic meters of stone were used in construction. At its completion, it was the tallest earthen dam in the entire world.

Starting point is 00:11:19 It took approximately six years to fill up Lake Nassar after the completion of the dam in 1970. The filling process began gradually with water levels rising year by year as the dam regulated the flow of the Nile. By 1976, the reservoir reached its maximum capacity, covering an area, of about 5,250 square kilometers, and extending over 500 kilometers into both Egypt and Sudan. The S-1 high dam began generating electricity in stages, with the first hydroelectric turbines becoming operational in 1967. The installation of all 12 turbines was completed by 1971, allowing the dam to reach its full hydroelectric capacity of 2.1 gigawatts. By that time, it was supplying about half of Egypt.

Starting point is 00:12:07 electricity, helping to industrialize the country and expand electrification to rural areas. The S-1 dam has certainly been a boon to the economy of Egypt. The amount of electricity produce has decreased as a percentage of overall electrical production, but it's still an important source of electricity. Since the creation of the dam, several problems have cropped up. One has to do with soil depletion. Without the floods to deposit fresh silt to rejuvenate the soil, farmland along the Nile has progressively become depleted, and this has resulted in the use of more chemical fertilizers, much of which gets washed into the Nile.

Starting point is 00:12:47 The other problem is that the silt, which used to be deposited in the floods, is now settling in Lake Nassar. As more silt settles in the lake, it reduces the amount of water that can be stored in the lake. This isn't a major problem yet, but in several decades, it will be. The lack of silt coming down the nigh, is also causing problems in the Nile Delta, as it's no longer getting silt to offset coastal erosion. One possible solution of the problem, which has yet to be implemented, would be the construction of

Starting point is 00:13:19 slurry pipes, which would transport the silt past the dam and into the river downstream. If you should ever get the chance, I highly recommend visiting Aswan. The dam itself actually isn't as interesting to visit as other dams like the Hoover Dam, but it's still worth a visit. The Philae temple is nearby, which is definitely worth a visit, as is Abu Symbol. It requires a bit more effort to get to Abu Simbo as it's close to the Sudanese border, but it is one of the highlights of Egypt. Also, Aswan gets far fewer visitors than Cairo or even Luxor, which can make it much more enjoyable. The Aswan High Dam has played a crucial role in economic development, energy production,

Starting point is 00:14:01 and agricultural expansion in Egypt. Despite its challenges, such as soil depletion, displacement of communities, and long-term sediment accumulation, it still remains one of the greatest landmarks in modern Egypt.
