El Oued Province
El Oued ( ar, ولاية الوادي, ber, ⴻⵍ oⵓⴻⴷ) is a Saharan province of Algeria (n° 39) dominated by '' Oued Souf''. It was named after its eponymous capital. Notable towns include El Oued itself and El M'Ghair, Djamaa and Guemar. Geography Physical geography El Oued Province lies in the Sahara desert in northeast Algeria. The mostly uninhabited southern half of the province is covered by the Grand Erg Oriental, a vast region of uninterrupted sand dunes. The northern half of the province is a mixture of sandy desert with scarce vegetation, scattered oases, and salt lakes. The most notable oases are the Oued Souf region, upon which the capital El Oued and neighbouring towns are built, as well as oases located near the towns of El M'Ghair and Djamaa, both of which support extensive palm plantations. Chott Melrhir, a large endorheic salt lake, lies in the north-central part of the province, while Chott Felrhir is a smaller salt lake to its southwest, near El M ...

Provinces Of Algeria
Algeria, since December 18, 2019, is divided into 58 wilaya, wilayas (province, provinces). Prior to December 18, 2019, there were 48 provinces. The 58 provinces are divided into 1,541 baladiyahs (Municipalities of Algeria, municipalities). The name of a province is always that of its capital city. According to the Algerian constitution, a wilaya is a territorial collectivity enjoying economic and diplomatic freedom, the APW, or ''"Popular Provincial Parliament/Provincial Popular Parliament"'' (the ''Assemblée Populaire Wilayale'', in French) is the political entity governing a province, directed by the "Wali (administrative title), Wali" (Governor), who is chosen by the Algerian President to handle the APW's decisions, the APW has also a president, who is elected by the members of the APW, which Algerians elect. List By 1984 the number of Algerian provinces were fixed at 48 and established the list of municipalities or "communes" attached to each province. In 2019, 10 new pr ...

Grand Erg Oriental
The Grand Erg Oriental (English: 'Great Eastern Sand Sea') is a large ''erg'' or "field of sand dunes" in the Sahara Desert. Situated for the most part in Saharan lowlands of northeast Algeria, the Grand Erg Oriental covers an area some 600 km wide by 200 km north to south. The erg's northeastern edge spills over into neighbouring Tunisia. Natural phenomena The Grand Erg Oriental is a desert, a natural region receiving very little rainfall. It is the largest ''Erg'' in Algeria, the next in size being the much smaller Grand Erg Occidental ('Western Sand Sea'). The largest erg of the Sahara is probably As-Sahra al-Libiyah, which straddles the inland border of Libya and Egypt. Erg is a Tamachek Berber word, and also a geographic term of art. The Grand Erg Oriental used to be associated with the Wadi Igharghar, a mostly dry and buried river with a sizable network of tributaries which, should it possess any water, would flow north into the erg from the Ahaggar mountains of ...

Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers. Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...

Chott Felrhir
In geology, a chott, shott, or shatt (; ar, شط, šaṭṭ, lit=bank, coast) is a salt lake in Africa's Maghreb that stays dry for much of the year but receives some water in the winter. The elevation of a chott surface is controlled by the position of the water table and capillary fringe, with sediment deflation occurring when the water table falls and sediment accumulation occurring when the water table rises.Swezey, C.S., 2003, The role of climate in the creation and destruction of continental stratigraphic records: An example from the northern margin of the Sahara Desert, in Cecil, C.B., and Edgar, N.T., eds., Climate Controls on Stratigraphy: SEPM (Society for Sedimentary Geology) Special Publication 77, p. 207-225. They are formed—within variable shores—by the spring thaw from the Atlas mountain range, along with occasional rainwater or groundwater sources in the Sahara, such as the Bas Saharan Basin.

Endorheic
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with open and closed lakes, exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔν ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chott Melrhir
Chott Melrhir () also known as Chott Melghir or Chott Melhir is an endorheic chott-kind of salt lake in northeastern Algeria. It is the westernmost part of a series of depressions, which extend from the Gulf of Gabès into the Sahara. They were created between Miocene and Early Pleistocene as a result of compression accompanying the formation of the Atlas Mountains. With the maximum area of about , it is the largest lake in Algeria.В. М.

Oued Souf
El Oued ( ar, اﻟﻮادي, ber, Suf meaning ''the River''), Souf or Oued Souf is a city, and the capital of El Oued Province, in Algeria. The oasis town is watered by an underground river, hence its name is El Oued which enables date palm cultivation and the rare use (for the desert) of brick construction for housing. As most roofs are domed, it is known as the "City of a Thousand Domes". El Oued is located south east of Algiers (the capital city of Algeria), near the Tunisian border. The population of El Oued was 134,699 as of the 2008 census, up from 105,256 in 1998, with a population growth rate of 2.5%. History In 11th, Fatimid Caliphate, Fatimids send Banu Hilal in Tripolitania, Tunisia and Constantine Province, Constantine area against Zirid dynasty, Zirids. Culture The inhabitants are thought to be Teroud tribe (Arabic: بنو طرود) living in and near Oued Souf area, however it is more likely that modern day Soufis are descendants of the original inhabitant ...
