Dongola Reach
The Dongola Reach is a reach of approximately 160 km in length stretching from the Fourth downriver to the Third Cataracts of the Nile in Upper Nubia, Sudan. Named after the Sudanese town of Dongola which dominates this part of the river, the reach was the heart of ancient Nubia. The Southern and the Northern Dongola Reach The area where the Nile flows from the Fourth Cataract to the southwest making a great S-shaped bend following the structure of the Central African Shear Zone is the Southern Dongola Reach. The area where it flows northward out of the bend and through to the Third Cataract is the Northern Dongola Reach. Geography In the ''Dongola Reach'' the Nile is without any significant perennial tributary inputs. It passes over mostly sandstone and is flanked by wide alluvial flood plains. In the ''Southern Dongola Reach'' the Nile is joined by the extinct river systems of Wadi Abu Dom, Wadi Muqaddam, Wadi Howar and Wadi Al-Malik. The ''Northern Dongola Reach'' contains ...

Makuria
Makuria (Old Nubian: , ''Dotawo''; gr, Μακουρία, Makouria; ar, المقرة, al-Muqurra) was a Nubian kingdom located in what is today Northern Sudan and Southern Egypt. Makuria originally covered the area along the Nile River from the Third Cataract to somewhere south of Abu Hamad as well as parts of northern Kordofan. Its capital was Dongola (Old Nubian: '), and the kingdom is sometimes known by the name of its capital. By the end of the 6th century, it had converted to Christianity, but in the 7th century, Egypt was conquered by the Islamic armies. In 651 an Arab army invaded, but it was repulsed and a treaty known as the ''Baqt'' was signed creating a relative peace between the two sides that lasted until the 13th century. Makuria expanded by annexing its northern neighbour Nobatia at some point in the seventh century, while also maintaining close dynastic ties with the kingdom of Alodia to the south. The period from the 9th to 11th century saw the peak of Makuri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Kerma Culture
The Kerma culture or Kerma kingdom was an early civilization centered in Kerma, Sudan. It flourished from around 2500 BC to 1500 BC in ancient Nubia. The Kerma culture was based in the southern part of Nubia, or "Upper Nubia" (in parts of present-day northern and central Sudan), and later extended its reach northward into Lower Nubia and the border of Egypt. The polity seems to have been one of a number of Nile Valley states during the Middle Kingdom of Egypt. In the Kingdom of Kerma's latest phase, lasting from about 1700 to 1500 BC, it absorbed the Sudanese kingdom of Sai and became a sizable, populous empire rivaling Egypt. Around 1500 BC, it was absorbed into the New Kingdom of Egypt, but rebellions continued for centuries. By the eleventh century BC, the more-Egyptianized Kingdom of Kush emerged, possibly from Kerma, and regained the region's independence from Egypt.

Palaeochannel
A palaeochannel, also spelt paleochannel and also known as palaeovalley or palaeoriver, is a geological term describing a remnant of an inactive river or stream channel that has been filled or buried by younger sediment. The sediments that the ancient channel is cut into or buried by can be unconsolidated, semi-consolidated, consolidated or Diagenesis, lithified. The word ''palaeochannel'' is formed from the ''palaeo'', meaning "old," and ''channel''. Recognition A palaeochannel is distinct from the overbank deposits of currently-active river channels, including ephemeral water courses that do not regularly flow (such as the Todd River, Central Australia) because the river bed is filled with sedimentary deposits unrelated to the normal bed load of the current drainage pattern. Many palaeochannels are arranged on old drainage patterns, distinct from the current drainage system of a catchment. For example, palaeochannels may relate to a system of rivers and creeks that drained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerma Basin
The Kerma Basin is a fertile low-lying area just below the Third Cataract of the Nile in Northern State, Sudan. Extending over a distance of about 60 km it is a flood plain in the Dongola Reach creating the largest section of arable land between Aswan and the Fourth Cataract of the Nile. At maximum extent some 70,000 acres (283 km2) can be inundated by the annual Nile flood, but a more regular year sees only about half that. This has led to a high population density in history that has long made the ''Kerma Basin'' one of the central portions of Nubia. The ancient city of Kerma was in the basin. During that period the Nile ran in channels spaced across the basin floor, increasing the amount of arable land and promoting the emergence of developed societies like the Kingdom of Kerma The Kerma culture or Kerma kingdom was an early civilization centered in Kerma, Sudan. It flourished from around 2500 BC to 1500 BC in ancient Nubia. The Kerma culture was based in the southern pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wadi Al-Malik
Wadi Al-Malik is the bed of an extinct river in Sudan. Following the Central African Shear Zone, it stretches for 560 km from the lake of Umm Badr in North Kurdufan NE-trending to the great bend of the Nile near Al Dabbah Al Dabbah (also known as ''Ed Debba'', ''El Debba'', ''El Debbah'' or ''Ed Debbah'') is a town on the river banks of the Nile, which is served by the Al Dabbah Airport. It has an estimated population of 52,000.

Wadi Howar
Wadi Howar (Wadi Howa) is a wadi in Sudan and Chad. Geography Originating in the Ennedi Region of Chad ''Wadi Howar'' runs through the Sudanese states of North Darfur and Northern to join the Nile north of the great bend opposite Old Dongola. Stretching over 1100 km in west–east direction across the southern fringes of the Libyan Desert, it ordinarily receives 25 mm of rainfall per year. Holocene period ''Wadi Howar'' is the remnant of the ancient ''Yellow Nile'', a tributary of the Nile during the Neolithic Subpluvial from about 9500 to 4500 years ago. At that time Savanna fauna and cattle-herders occupied this region and the southern edge of the Sahara was some 500 km further north than it is today. When the Sahara underwent desertification between 6000 and 4000 years ago, the wadi first became a chain of freshwater lakes and marshes, as shown by Ptolemy's world map, then it became extinct about 2000 years ago.

Wadi Muqaddam
Geography Wadi Muqaddam is a dry water course some 320 km extending from beyond Omdurman north to the great bend of the Nile near Korti. It gives its name to the geological Wadi Milk Formation. Delimiting the Bayuda Desert to the west it still flows during rainy seasons. Some scholars assume ''Wadi Muqaddam'' as a former channel of the White Nile.D. Q. Fuller and L. Smith, ''The Prehistory of the Bayuda: New Evidence from the Wadi Muqaddam'' In: Kendall, T, (ed.) Nubian Studies 1998.

Flood Plain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...
