9 Interesting Facts About The Nile River

The Nile is one of the most well-known rivers worldwide, and for good reason. While all rivers are crucial for nearby communities and wildlife, the Nile stands out for several reasons.

Here are a couple of reasons why this river is so significant and fascinating.

1. It’s the longest river on Earth.

9 Interesting Facts About The Nile River

The Nile River stretches northward for approximately 6,650 kilometers (4,132 miles) from the African Great Lakes through the Sahara desert until it reaches the Mediterranean Sea. It passes through 11 countries: Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. The Nile drains an area of 3.3 million square kilometers (1.3 million square miles), roughly 10% of the African continent.

Although the Nile is often considered the longest river on Earth, determining its exact length can be tricky due to various factors, such as where its source and mouth are defined. Scientists typically measure the longest continuous channel in a river system to determine its length. The Nile is slightly longer than the Amazon River, but in 2007, Brazilian scientists claimed to have found the Amazon to be longer. However, their study was not published, and many experts doubt its accuracy. Despite this, organizations like the United Nations and the Guinness Book of World Records generally recognize the Nile as the world’s longest river.

2. There’s more than one Nile.

In ancient times, the Lower Nile flooded during the summer, puzzling early Egyptians because their region rarely experienced rainfall. Although the Nile is one river in Egypt, it receives water from much rainier areas to the south. Its water levels are influenced by different patterns of water flow, known as “hydraulic regimes,” upstream.

The Nile has three main branches: the White Nile, the Blue Nile, and the Atbara. The White Nile starts from streams that flow into Lake Victoria, the largest tropical lake in the world. Before reaching Lake Albert, it goes through various stages, including Lake Kyoga and Murchison Falls. Then, it becomes the Albert Nile, later transforming into the Mountain Nile in South Sudan and eventually joining the Gazelle River to become the White Nile. Near Khartoum, Sudan, it meets the Blue Nile.

The White Nile flows steadily throughout the year, while the Blue Nile has most of its activity during a few wild months in the summer. Both the Blue Nile and the Atbara receive water from the highlands of Ethiopia, where monsoon patterns cause the rivers to alternate between heavy flows in the summer and lower flows in the winter. Although the White Nile is longer and more consistent, the Blue Nile contributes around 60% of the water that reaches Egypt each year, mostly during the summer. The Atbara adds about 10% of the Nile’s total flow, with most of its water arriving between July and October. These rains flood the Nile in Egypt annually, and as they erode basalt lavas in Ethiopia, the water becomes particularly valuable downstream.

3. People spent centuries searching for its source.

The Nile River was highly esteemed by ancient Egyptians as the giver of life, yet its origins remained a mystery for centuries. Many expeditions failed to uncover its source, with explorers like the Egyptians, Greeks, and Romans encountering obstacles like the Sudd, a vast swamp in what is now South Sudan. This added to the river’s mystique, leading to depictions in classical Greek and Roman art portraying it as a god with a hidden face.

The Blue Nile’s source was discovered first, possibly traced by an ancient Egyptian expedition back to Ethiopia. However, finding the source of the White Nile proved more challenging. Scottish explorer David Livingstone, famously encountered by Welsh journalist Henry Morton Stanley in 1871, searched for it unsuccessfully. European explorers had only recently found Lake Victoria. After Livingstone died in 1873, Stanley and East African explorer Sidi Mubarak Bombay helped confirm Lake Victoria’s connection to the Nile.

The search continued as the White Nile began even before Lake Victoria. The Kagera River flows into Lake Victoria from Lake Rweru in Burundi, but it receives water from other tributaries like the Ruvubu and the Nyabarongo. Rivers from Rwanda’s Nyungwe Forest feed the Nyabarongo, and some believe this to be the farthest source of the Nile.

4. It takes a strange detour in the desert.

9 Interesting Facts About The Nile River

After flowing northward for much of its journey, the Nile River is surprised by veering southwest amid the Sahara Desert. This unexpected turn happens after its main tributaries merge in Sudan. It travels in this direction for about 300 kilometers, appearing to head back toward Central Africa rather than continuing to Egypt.

This diversion, known as the “Great Bend,” is caused by a massive underground rock formation called the Nubian Swell. Formed over millions of years due to tectonic uplift, the Nubian Swell forced the Nile to make this dramatic curve, creating the Nile’s cataracts. According to a geological overview by the University of Texas at Dallas, the sediment-laden Nile would have eroded these rocky river stretches much more quickly without this uplift.

5. Its mud helped shape human history.

As the Nile flows into Egypt, it transforms a stretch of the Sahara desert along its banks. This transformation is noticeable even from space, where a long, green oasis contrasts with the tan landscape surrounding it.

The Sahara is the largest hot desert on Earth, and changing it in this way is no small feat. The Lower Nile historically flooded in the summer, bringing water from Ethiopia and soaking the desert soil in its floodplain. However, the water wasn’t the only factor in taming the Sahara. The Nile also carried sediment collected along the way, particularly black silt eroded by the Blue Nile and Atbara from basalt in Ethiopia. These silty floodwaters would flow into Egypt each summer, leaving behind a valuable black mud after drying up.

Around 6000 BCE, people started living on the banks of the Nile, and by 3150 BCE, these settlements had formed the world’s first nation-state. Egypt quickly developed a rich culture, thriving for nearly 3,000 years as the leading nation in the Mediterranean region, thanks to the Nile’s water and fertile land.

Although Egypt was later conquered by other empires, it continued to flourish with the Nile’s support. Today, it’s home to nearly 100 million people, with 95% living close to the Nile. Egypt is Africa’s third most populous country and is filled with ancient treasures like pyramids and mummies, showcasing its rich history. Without the Nile, surviving in this desert would have been extremely difficult. The Nile’s impact on human history is immense, as it played a crucial role in the rise of civilization, shaping Egypt’s story and captivating people’s imaginations for centuries.

6. It’s a haven for wildlife, too.

The Nile is vital for humans and many other species living in the ecosystems it travels through. Near the White Nile’s beginning, it flows through lush tropical rainforests filled with diverse plants like banana trees, bamboo, coffee shrubs, and ebony. As it moves north, it transitions to mixed woodland and savanna, with fewer trees and more grasses and shrubs. During the rainy season, it forms vast swamps, including the famous Sudd in South Sudan, covering nearly 260,000 square kilometers. As it heads further north, the vegetation decreases until it almost disappears in the desert.

One significant plant along the Nile is papyrus, a tall reed that grows in shallow water. Ancient Egyptians used papyrus to make various items like paper, cloths, mats, and sails. While it still grows naturally in Egypt, it’s not as common in the wild today as it once was.

The Nile is home to a diverse range of animals, including many types of fish like Nile perch, catfish, and tilapia. It’s also a haven for various bird species, providing a vital habitat for migrating flocks.

Some large animals, like hippos, used to be widespread along the river but are now mostly found in swampy areas like the Sudd in South Sudan. Other notable animals include soft-shelled turtles, cobras, black mambas, and water snakes. The Nile crocodile, known for its size, is perhaps the most famous. These crocodiles can grow up to 6 meters long and are found in most parts of the river.

7. It was home to a crocodile god and a Crocodile City.

Ancient Egyptians considered the Nile River very important, calling it Ḥ’pī or Iteru, which means “river.” They also named it Ar or Aur, meaning “black,” because of its fertile mud. They believed the Nile was essential for life and incorporated it into their myths and beliefs.

For instance, they saw the Milky Way as a reflection of the Nile, and the sun god Ra was thought to sail his ship across it. They believed the Nile embodied gods like Hapi, who brought life to the land, and Ma’at, who represented truth and harmony. Hathor, a goddess associated with the sky, women, and fertility, was also linked to the Nile.

Crocodiles held significant importance in ancient Egyptian mythology, particularly in the story of Osiris and Set. According to the myth, Osiris, betrayed by his brother Set, was thrown into the Nile, and his body was dismembered. His wife, Isis, searched for and found all parts except his penis, which a Nile crocodile ate. This event associated crocodiles with fertility, linked to the god Sobek.

In the city of Shedet, now Faiyum, crocodiles were revered. It was known as “Crocodilopolis” as residents worshipped Sobek and kept a sacred crocodile named “Petsuchos” adorned with jewelry in a temple.

8. It may be a window to the real underworld.

9 Interesting Facts About The Nile River

According to ancient Egyptian mythology, Osiris couldn’t be resurrected without his entire body, so he became the god of the dead and ruler of the underworld instead. The Nile was seen as a gateway to the afterlife, with its eastern side symbolizing life and the western side representing the land of the dead. While the Nile is rich with ancient spiritual connections, modern science suggests it might also reveal insights about Earth’s mantle.

Researchers have debated the Nile’s age, but a 2019 study indicates that its drainage system has been stable for about 30 million years—much longer than previously believed. During the Oligocene Epoch, the Nile’s course would have looked remarkably similar to its current path. This stability is due to a consistent topographic gradient, maintained by currents in the mantle, the hot rock layer beneath Earth’s crust.

The study suggests that a mantle plume mirrors the Nile’s northward flow, helping maintain its path for millions of years. This phenomenon, where mantle plumes influence surface topography, isn’t new, but the Nile’s vast basin provides a unique opportunity to study these interactions on a large scale. Understanding this relationship could help scientists gain new insights into the inner workings of our planet by studying the Nile and other rivers.

9. It’s changing.

9 Interesting Facts About The Nile River

People have influenced the Nile for thousands of years, but things have changed recently. A major change happened in 1970 with the completion of the Aswan High Dam in southern Egypt, creating a large reservoir called Lake Nasser. This dam gave humans control over the Nile’s floods for the first time. It benefits Egypt’s economy by releasing water where and when needed, and its 12 turbines generate 2.1 gigawatts of electricity.

However, the dam has also caused problems. The black silt that used to enrich the Sahara is now trapped behind the dam, accumulating in the reservoir and canals instead of flowing north. This silt once helped grow the Nile Delta, but now the delta is shrinking due to erosion from the Mediterranean Sea. The dam has also led to a decline in the fertility and productivity of farmland along the Nile. According to Britannica, “Egypt’s annual application of about 1 million tons of artificial fertilizers is an inadequate substitute for the 40 million tons of silt formerly deposited annually by the Nile flood.” Fish populations offshore from the delta have also declined due to the loss of nutrients from the Nile silt.

It’s not just the Aswan High Dam that has changed the Nile. Sudan has some older dams on Nile tributaries, like the Blue Nile’s Sennar Dam, opened in 1925, and the Atbara’s Khashm el-Girba Dam, opened in 1964. While these dams don’t affect the river as much as the Aswan High Dam, they have still made an impact. Additionally, a project in Ethiopia has raised concerns about water supplies downstream, showing how human intervention can have complex and far-reaching effects on natural ecosystems.

The Grand Ethiopian Renaissance Dam (GERD), located on the Blue Nile, has been under construction since 2011 and costs $5 billion. Once fully operational in 2022, it is expected to generate 6.45 gigawatts of electricity. This could be transformative for Ethiopia, where about 75% of the population lacks access to electricity. Selling extra electricity to neighboring countries could potentially earn Ethiopia $1 billion annually.

However, to achieve these benefits, the dam needs to hold back a significant amount of water that would usually flow to Sudan and Egypt. This has caused concern in those countries, which already face water shortages. The dam’s reservoir will be more than twice the size of Lake Mead, the largest reservoir in the U.S., held by the Hoover Dam. It will eventually hold 74 billion cubic feet of water from the Blue Nile, according to Yale Environment 360. Filling the reservoir could take between five to 15 years.

During this filling period, the freshwater flow from the Nile to Egypt could be reduced by 25%, resulting in a loss of a third of the electricity generated by the Aswan High Dam, according to researchers in GSA Today, a journal by the Geological Society of America. Many Egyptians worry that the dam will limit water supplies even after the reservoir is filled, worsening issues related to population growth, water pollution, land subsidence, climate change, and the loss of silt at Aswan.

Egypt, Ethiopia, and Sudan have made little progress despite nearly a decade of on-and-off negotiations. However, they reached an initial deal at a meeting in January 2020, marking a breakthrough in their long-running dispute. The three countries are now holding follow-up talks, hoping to finalize a “comprehensive, cooperative, and sustainable agreement.”

While this is promising, there are still many details to be resolved. Additionally, the challenge of sharing limited water resources among growing populations will persist, regardless of the negotiations’ outcome. The GSA Today study highlights that Ethiopia and Sudan have proposed building more dams on the Nile. With about 400 million people living in Nile countries, many already facing droughts and energy shortages, it’s likely that even more water will need to stay upriver in the coming years.
