Second 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 was located just south of 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. It is located 10 km south of the former site of Wadi Halfa, at the current location of the town () *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 C ...

Nubia Today
Nubia (, Nobiin: , ) is a region along the Nile river encompassing the area between the confluence of the Blue and White Niles (in Khartoum in central Sudan), and the first cataract of the Nile (south of Aswan in southern Egypt) 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. From the 3rd century BC to 3rd century AD, northern Nubia was invaded and annexed to Egypt, ruled by the Greeks and Romans. This territory was known in the Greco-Roman world as Dodekaschoinos. Kush's collapse in the fourth century AD was preceded by an invasion from the Et ... [...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, 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 (; ; – ) was an Ancient Greek polymath: a Greek mathematics, mathematician, geographer, poet, astronomer, and music theory, music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. His work is comparable to the study of geography, and he introduced some of the terminology, even coining the terms geography and geographer. He is best known for being the first person known to calculate the Earth's circumference, which he did by using the extensive survey results he could access in his role at the Library. His calculation was remarkably accurate (his error margin turned out to be less than 1%). He was the first to calculate Earth's axial tilt, which similarly proved to have remarkable accuracy. He created the Eratosthenes' Map of the World, first global projection of the world, incorporating Circle of latitude, parallels and Longitude, meridians based on the available geographic knowledge of his era.

Ancient Egypt
Ancient Egypt () was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of List of Egyptologists, Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Periodization of ancient Egypt, Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of Egypt, Old Kingdom of the Early Bronze Age; the Middle Kingdom of Egypt, Middle Kingdom of the Middle Bronze Age; or the New Kingdom of Egypt, New Kingdom of the Late Bronze Age. The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt ...

Kingdom Of Kush
The Kingdom of Kush (; Egyptian language, Egyptian: 𓎡𓄿𓈙𓈉 ''kꜣš'', Akkadian language, Assyrian: ''Kûsi'', in LXX Χους or Αἰθιοπία; ''Ecōš''; ''Kūš''), 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. 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" probably from the indigenous ethnonym "Kasu", 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 pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nile Delta
The Nile Delta (, or simply , ) is the River delta, delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the world's larger deltas—from Alexandria in the west to Port Said in the east; it covers of the 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 distributary, distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same names. In the past, the delta had several distributaries, but these have been lost due to flood management, flood control, silting and changing relief. One such defunct distributary is Wadi Tumilat. The Suez Canal is east of the delta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Egypt
Upper Egypt ( ', shortened to , , locally: ) is the southern portion of Egypt and is composed of the Nile River valley south of the delta and the 30th parallel North. It thus consists of the entire Nile River valley from Cairo south to Lake Nasser (formed by the Aswan High Dam). Name In ancient Egypt, Upper Egypt was known as ''tꜣ šmꜣw'', literally "the Land of Reeds" or "the Sedgeland", named for the sedges that grow there. In Biblical Hebrew it was known as and in Akkadian it was known as . Both names originate from the Egyptian '' pꜣ- tꜣ- rsj'', meaning "the southern land". In Arabic, the region is called Sa'id or Sahid, from صعيد meaning "uplands", from the root صعد meaning to go up, ascend, or rise. Inhabitants of Upper Egypt are known as Sa'idis and they generally speak Sa'idi Egyptian Arabic. 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- ...

Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), 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 Solvation, 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 Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...
