Chott El Hodna
The ''Chott el Hodna'' ( ar, شط الحضنة) is a very shallow saline lake in Algeria. It is located within an endorheic basin in the Hodna region, towards the eastern end of the ''Hautes Plaines''. The ''Chott el Hodna'' includes seasonal brackish and saline pools and marshes, but the central zone of the lake is characterized by a complete absence of vegetation. J. Despois argues that the ''Chott el Hodna'' is not a proper '' Chott'', but a '' Sebkha''. Ecology The ''chott'' area provides an important habitat for certain endangered species such as the Cuvier's gazelle, the marbled duck and different kinds of bustards, as well as indigenous fish species. The ''Chott el Hodna'' was declared a Ramsar site on 2 February 2001.

Hodna
The Hodna (french: Le Hodna) is a natural region of Algeria located between the Tell and Saharan Atlas ranges at the eastern end of the ''Hautes Plaines''. It is a vast depression lying in the northeastern section of M'Sila Province and the western end of Batna Province. Geography The Hodna region has a length of about 120 km in an NW - SE direction and a width of about 80 km. It is characterized by the Chott El Hodna, an endorheic salt lake, in its centre with seasonal brackish and saline pools and marshes. A thin film of water collects during wet seasons on the level terrain of the large lake basin, which becomes a salt flat when it dries. The elevation of the lake's surface is slightly below 400 m, while the surrounding steppe-like plain, characterized by wadis and oases, averages between 500 and 600 meters in elevation in the communes near the lake. The Hodna natural region gives its name to the Hodna Mountains located to the north. Its southern limit is marked by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geography Of M'Sila Province
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lakes Of Algeria
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Algeria
Algeria comprises square kilometers of land, more than 80% of which is desert, in North Africa, between Morocco and Tunisia. It is the largest country in Africa. Its Arabic name, Al Jazair (the islands), is believed to derive from the rocky islands along the coastline of the Mediterranean Sea. The northern portion, an area of mountains, valleys, and plateaus between the Mediterranean and the Sahara Desert, forms an integral part of the section of North Africa known as the Maghreb. This area includes Morocco, Tunisia, and the northwestern portion of Libya known historically as Tripolitania.

Marbled Duck
The marbled duck, or marbled teal (''Marmaronetta angustirostris'') is a medium-sized species of duck from southern Europe, northern Africa, and western and central Asia. The scientific name, ''Marmaronetta angustirostris'', comes from the Greek ''marmaros'', marbled and ''netta'', a duck, and Latin ''angustus'', narrow or small and ''-rostris'' billed. Distribution, habitat and breeding This duck formerly bred in large numbers in the Mediterranean region, but is now restricted to a few sites in southern Spain, southern Italy, northwest Africa and the broader Levant. Further east it survives in the Mesopotamian marshland in southern Iraq and in Iran (Shadegan Marshes - the world's most important site), as well as isolated pockets in Armenia, Azerbaijan, South European Russia, western India and western China. In general the species has nomadic tendencies. In some areas birds disperse from the breeding grounds, and have been encountered in the winter period in the Sahel zone, so ...

Sabkha
A sabkha ( ar, سبخة) is a coastal, supratidal mudflat or sandflat in which evaporite-saline minerals accumulate as the result of semiarid to arid climate. Sabkhas are gradational between land and intertidal zone within restricted coastal plains just above normal high-tide level. Within a sabkha, evaporite-saline minerals sediments typically accumulate below the surface of mudflats or sandflats. Evaporite-saline minerals, tidal-flood, and aeolian deposits characterize many sabkhas found along modern coastlines. The accepted type locality for a sabkha is at the southern coast of the Persian Gulf, in the United Arab Emirates.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds.

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
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.
