The Cataracts of the Nile are shallow lengths (or whitewater rapids) of the Nile river, between Khartoum and Aswan, where the surface of the water is broken by many small boulders and stones jutting out of the river bed, as well as many rocky islets. In some places, these stretches are punctuated by whitewater, while at others the water flow is smoother but still shallow.

Geologists indicate that the region of northern Sudan is tectonically active and this activity has caused the river to take on "youthful" characteristics. [1] The Nubian Swell has diverted the river's course to the west, while keeping its depth shallow and causing the formation of the cataracts. Even as the river bed is worn down by erosion, the landmass is lifted, keeping parts of the river bed exposed. These distinctive features of the river between Aswan and Khartoum have led to the stretch being often referred to as the Cataract Nile, while the downstream portion is occasionally referred to as the "Egyptian" Nile. The geological distinction between these two portions of the river is considerable. North of Aswan, the river bed is not rocky, but is instead composed of sediment, and far from being a shallow river. It is believed [2] that the bedrock was previously eroded to be several thousand feet deep. This created a vast canyon that is now filled with sediment.
Despite these characteristics, some of the cataracts which are normally impassable by boat because of the shallow water have become navigable during the flood season.
The word "cataract" comes from the Greek word καταρρέω ("to flow down"), although the original Greek term was the plural-only Κατάδουποι. However, contrary to this, none of the Nile's six primary cataracts could be accurately described as waterfalls, and given a broader definition, this is the same with many of the minor cataracts.
In ancient times, Upper Egypt extended from south of the Nile Delta to the first cataract, while further upstream, the land was controlled by the ancient Kingdom of Kush that would later take over Egypt from 760 to 656 BC. [3] Besides the Kushite invasion, for most of Egyptian history, the Nile's cataracts, particularly the First Cataract, primarily served as a natural border to prevent most crossings from the south, as those in said region would rely on river travel to venture north and south. This allowed Egypt's southern border to be relatively protected from invasions, and besides brief Kushite rule, it remained a natural border for most of Egyptian history. [4]
Eratosthenes gave a precise description of the Cataract-Nile: [5]
It has a similar shape to a backwards letter N. It flows northward from Meroë about 2700 stadia, then turns back to the south and the winter sunset for about 3700 stadia, and it almost reaches the same parallel as the Meroë region and makes its way far into Libya. Then it makes another turn, and flows northward 5300 stadia to the great cataract, curving slightly to the east; then 1200 stadia to the smaller cataract at Syene (i.e. Aswan), and then 5300 more to the sea.
The six cataracts of the Nile are depicted extensively by European visitors, notably by Winston Churchill in The River War (1899), where he recounts the exploits of the British trying to return to the Sudan between 1896 and 1898, after they were forced to leave in 1885.
Today, Lake Nasser has filled most of the area between the first and second cataracts (known as Lower Nubia), and its monuments moved as part of the International Campaign to Save the Monuments of Nubia.
The history of Sudan refers to the territory that today makes up Republic of the Sudan and the state of South Sudan, which became independent in 2011. The territory of Sudan is geographically part of a larger African region, also known by the term "Sudan". The term is derived from Arabic: بلاد السودان bilād as-sūdān, or "land of the black people", and has sometimes been used more widely referring to the Sahel belt of West and Central Africa.
Nubians are a Nilo-Saharan speaking ethnic group indigenous to the region which is now northern Sudan and southern Egypt. They originate from the early inhabitants of the central Nile valley, believed to be one of the earliest cradles of civilization. In the southern valley of Egypt, Nubians differ culturally and ethnically from Egyptians, although they intermarried with members of other ethnic groups, especially Arabs. They speak Nubian languages as a mother tongue, part of the Northern Eastern Sudanic languages, and Arabic as a second language.
Lake Nasser is a large reservoir in southern Egypt and northern Sudan. It was created by the construction of the Aswan High Dam and is one of the largest man-made lakes in the world. Before its creation, the project faced opposition from Sudan as it would encroach on land in the northern part of the country, where many Nubian people lived who would have to be resettled. In the end Sudan's land near the area of Lake Nasser was mostly flooded by the lake. The lake has become an important economic resource in Egypt, improving agriculture and touting robust fishing and tourism industries.
Meroë was an ancient city on the east bank of the Nile about 6 km north-east of the Kabushiya station near Shendi, Sudan, approximately 200 km north-east of Khartoum. Near the site is a group of villages called Bagrawiyah. This city was the capital of the Kingdom of Kush for several centuries from around 590 BC, until its collapse in the 4th century AD. The Kushitic Kingdom of Meroë gave its name to the "Island of Meroë", which was the modern region of Butana, a region bounded by the Nile, the Atbarah and the Blue Nile.
The Nubian pyramids were constructed by the rulers of the ancient Kushite kingdoms in the region of the Nile Valley known as Nubia, located in present-day northern Sudan. This area was the site of three ancient Kushite kingdoms. The capital of the first was at Kerma, the second was centered on Napata and the third was centered on Meroë.
Lower Nubia is the northernmost part of Nubia, roughly contiguous with the modern Lake Nasser, which submerged the historical region in the 1960s with the construction of the Aswan High Dam. Many ancient Lower Nubian monuments, and all its modern population, were relocated as part of the International Campaign to Save the Monuments of Nubia; Qasr Ibrim is the only major archaeological site which was neither relocated nor submerged. The intensive archaeological work conducted prior to the flooding means that the history of the area is much better known than that of Upper Nubia. According to David Wengrow, the A-Group Nubian polity of the late 4th millenninum BCE is poorly understood since most of the archaeological remains are submerged underneath Lake Nasser.
Napata was a city of ancient Kush at the fourth cataract of the Nile founded by the Egyptian Amun cult for Egyptian pilgrims given by its, as suggested, Egyptian name. It is located approximately 1.5 kilometers from the east side of the river at the site of modern Karima, Sudan.
The Temple of Debod is an ancient Nubian temple currently located in Madrid, Spain. The temple was originally erected in the early 2nd century BC 15 km (9.3 mi) south of Aswan, Egypt. The Egyptian government donated the temple to Spain in 1968 as a sign of gratitude for their participation in the International Campaign to Save the Monuments of Nubia. It was dismantled, transported, and rebuilt in the Parque de la Montaña in 1970–1972. It is one of the few works of ancient Egyptian architecture relocated outside Egypt and the only one of its kind in Spain.
Bigeh is an island and archaeological site situated along the Nile River in historic Nubia and within the Aswan Governorate of southern Egypt. The island has been situated in the reservoir of the Old Aswan Dam since the dam's initial completion in 1902.
The Butana, historically called the Island of Meroë, is the region between the Atbara and the Nile in the Sudan. South of Khartoum it is bordered by the Blue Nile and in the east by Lake Tana in Ethiopia. It should not be confused with the Gezira, the region west of the Blue Nile and east of the White Nile.
The National Museum of Sudan or Sudan National Museum, abbreviated SNM, is a two-story building, constructed in 1955 and established as national museum in 1971.
Temple of Al-Maharraqa is an ancient Egyptian Temple dedicated to Isis and Serapis. It was originally located in al-Maharraqa, Lower Nubia, approximately 120 km (75 mi) south of Aswan on the southern border of the Roman Empire. In the 1960s it was relocated as part of the International Campaign to Save the Monuments of Nubia.
Nubian architecture is diverse and ancient. Permanent villages have been found in Nubia, which date from 6000 BC. These villages were roughly contemporary with the walled town of Jericho in Palestine.
Nubia is a region along the Nile river encompassing the confluence of the Blue and White Niles, and the area between the first cataract of the Nile or more strictly, Al Dabbah. It was the seat of one of the earliest civilizations of ancient Africa, the Kerma culture, which lasted from around 2500 BC until its conquest by the New Kingdom of Egypt under Pharaoh Thutmose I around 1500 BC, whose heirs ruled most of Nubia for the next 400 years. Nubia was home to several empires, most prominently the Kingdom of Kush, which conquered Egypt in the eighth century BC during the reign of Piye and ruled the country as its 25th Dynasty.
The Kingdom of Kush, also known as the Kushite Empire, or simply Kush, was an ancient kingdom in Nubia, centered along the Nile Valley in what is now northern Sudan and southern Egypt.
Abu Simbel is a village in the Egyptian part of Nubia, about 240 km (150 mi) southwest of Aswan and near the border with Sudan. As of 2012, it has about 2600 inhabitants. It is best known as the site of the Abu Simbel temples, which were built by King Ramses II.
The geographical region of ancient Nubia covers the area from the First Cataract at Aswan in the north, to the Blue and White Niles at Khartoum in the south, and adjacent deserts. The region includes the Nile Valley of lower Egypt and nowadays Sudan. The earliest history of Nubia dates to the Paleolithic period, and the civilization of ancient Nubia developed alongside ancient Egypt on the Nile valley. Both Egypt and Nubia are characterized by their distinct cultural identities and had lots of interactions—military, political, and commercial—throughout history. Prior to Roman contact, Kush had trade relations with Ptolemaic Egypt. The early interaction between Rome and the kingdom of Kush in Nubia was full of tensions and conflicts before Caesar Augustus established a peace treaty with Kush. Nubia thereby flourished for nearly three centuries through trade with Roman Egypt. Archaeological excavations and written accounts by Classical authors such as Strabo, Pliny the Elder, and Diodorus are important sources of information about Roman relations with Nubia.
Korosko was a settlement on the Nile River in Egyptian Nubia. It was located 118 miles (190 km) south of Aswan and served as the point of departure for caravans avoiding the Dongola bend in the river by striking out directly across the desert to Abu Hamad and thereby bypassing the second, third and fourth cataracts of the Nile. The "Korosko route" or "Korosoko road" was in use during the period of the New Kingdom, when Pharaohs Thutmose I and Thutmose III marked it with boundary stelae. During the Meroitic period it was the main connection between the Kingdom of Kush and the Mediterranean world.
The Triakontaschoinos, Latinized as Triacontaschoenus, was a geographical and administrative term used in the Greco-Roman world for the part of Lower Nubia between the First and Second Cataracts of the Nile, which formed a buffer zone between Egypt and later Rome on the one hand and Meroë on the other hand. The northern part of this area, stretching from the First Cataract south to Maharraqa, was known as the Dodekaschoinos or Dodecaschoenus. In the Ptolemaic and Roman periods the Dodekaschoinos was often annexed to Egypt or controlled from it, and the rest of the Triakontaschoinos sometimes was as well.
Upper Nubia is the southernmost part of Nubia, upstream on the Nile from Lower Nubia. It is so called because the Nile flows north, so it is further upstream and of higher elevation in relation to Lower Nubia.
