Sixth Cataract
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. The Six Cataracts Counted going upstream (from north to south): In Egypt: *The First Cataract cuts through Aswan (). Its former location was selected for the construction of Aswan Low Dam, the first dam built across the Nile. In Sudan: *The Second Cataract (or Great Cataract) was in Nubia and is now submerged under Lake Nasser. () *The Third Cataract is at Tombos/Hannek. () *The Fourth Cataract is in the Manasir Desert, and since 2008, is submerged under the reservoir of Merowe Dam. () *The Fifth Cataract is near the confluence of the Nile and Atbarah Rivers. () *The Sixth Cataract is where the Nile cuts t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nubia Today
Nubia () (Nobiin: Nobīn, ) is a region along the Nile river encompassing the area between the first cataract of the Nile (just south of Aswan in southern Egypt) and the confluence of the Blue and White Niles (in Khartoum in central Sudan), 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 (to be replaced a century later by the native Egyptian 26th Dynasty). From the 3rd century BC to 3rd century AD, northern Nubia would be invaded and annexed to Egypt, ruled by the Greeks and Romans. This territory would be known in the Greco-Roman world as Dodekasch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The River War
''The River War: An Historical Account of the Reconquest of the Soudan'' (1899), by Winston Churchill. It is a history of the conquest of the Sudan between 1896 and 1899 by Anglo-Egyptian forces led by Lord Kitchener.

Eratosthenes
Eratosthenes of Cyrene (; grc-gre, Ἐρατοσθένης ; – ) was a Greek polymath: a mathematician, geographer, poet, astronomer, and music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. His work is comparable to what is now known as the study of geography, and he introduced some of the terminology still used today. He is best known for being the first person known to calculate the circumference of the Earth, which he did by using the extensive survey results he could access in his role at the Library; his calculation was remarkably accurate. He was also the first to calculate Earth's axial tilt, which has also proved to have remarkable accuracy. He created the first global projection of the world, incorporating parallels and meridians based on the available geographic knowledge of his era. Eratosthenes was the founder of scientific chronology; he used Egyptian and Persian records to estimate the dates of the main ...

Kingdom Of Kush
The Kingdom of Kush (; Egyptian language, Egyptian: 𓎡𓄿𓈙𓈉 ''kꜣš'', Akkadian language, Assyrian: ''Kûsi'', in LXX grc, Κυς and Κυσι ; cop, ''Ecōš''; he, כּוּשׁ ''Kūš'') was an ancient kingdom in Nubia, centered along the Nile Valley in what is now northern Sudan and southern Egypt. The region of Nubia was an early cradle of civilization, producing several complex societies that engaged in trade and industry. The city-state of Kerma emerged as the dominant political force between 2450 and 1450 BC, controlling the Nile Valley between the first and fourth Cataracts of the Nile, cataracts, an area as large as Egypt. The Egyptians were the first to identify Kerma as "Kush" and over the next several centuries the two civilizations engaged in intermittent warfare, trade, and cultural exchange. Much of Nubia came under Egyptian rule during the New Kingdom of Egypt, New Kingdom period (1550–1070 BC). Following Egypt's disintegration amid the Lat ...

Nile Delta
The Nile Delta ( ar, دلتا النيل, or simply , is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers of Mediterranean coastline and is a rich agricultural region. From north to south the delta is approximately in length. The Delta begins slightly down-river from Cairo. Geography From north to south, the delta is approximately in length. From west to east, it covers some of coastline. The delta is sometimes divided into sections, with the Nile dividing into two main distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same name. In the past, the delta had several distributaries, but these have been lost due to flood control, silting and changing relief. One such defunct distributary is Wadi Tumilat. The Suez Canal is east of the delta and enters the coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Egypt
Upper Egypt ( ar, صعيد مصر ', shortened to , , locally: ; ) is the southern portion of Egypt and is composed of the lands on both sides of the Nile that extend upriver from Lower Egypt in the north to Nubia in the south. In ancient Egypt, Upper Egypt was known as ''tꜣ šmꜣw'', literally "the Land of Reeds" or "the Sedgeland". It is believed to have been united by the rulers of the supposed Thinite Confederacy who absorbed their rival city states during the Naqada III period (c. 3200–3000 BC), and its subsequent unification with Lower Egypt ushered in the Early Dynastic period. Upper and Lower Egypt became intertwined in the symbolism of pharaonic sovereignty such as the Pschent double crown. Upper Egypt remained as a historical region even after the classical period. Geography Upper Egypt is between the Cataracts of the Nile beyond modern-day Aswan, downriver (northward) to the area of El-Ayait, which places modern-day Cairo in Lower Egypt. The northern (d ...

Plurale Tantum
A ''plurale tantum'' (Latin for "plural only"; ) is a noun that appears only in the plural form and does not have a singular variant for referring to a single object. In a less strict usage of the term, it can also refer to nouns whose singular form is rarely used. In English, ''pluralia tantum'' are often words that denote objects that occur or function as pairs or sets, such as ''spectacles'', ''trousers'', ''pants'', ''scissors'', ''clothes'', or ''genitals''. Other examples are for collections that, like ''alms'' and ''feces'', cannot conceivably be singular. Other examples include '' suds'', ''jeans'', ''outskirts'', ''odds'', ''riches'', ''surroundings'', ''thanks'', and ''heroics''. In some languages, ''pluralia tantum'' refer to points or periods of time (for example, Latin 'calends, the first day of the month', German 'vacation, holiday') or to events (for example, Finnish 'wedding' and 'face'). In some cases there is no obvious semantic reason for a particular noun t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nubian Swell
The Nubian Swell is a geology, geologic structural swell (geology), uplift in northern Africa that trends east to west and separates the lower Nile River, Nile of Egypt from the Sudan basin. The Nubian Swell has been geologically active since early Mesozoic times, and portions of it are still active. The Nile traverses the uplift through geologic fractures and faults, and four of six cataracts of the Nile occur at places that the river crosses the uplift.
