Geography Of Tunisia
Tunisia is a country in Northern Africa, bordering the Mediterranean Sea, having a western border with Algeria (965 km) and south-eastern border with Libya (459 km) where the width of land tapers to the south-west into the Sahara. The country has north, east and complex east-to-north coasts including the curved Gulf of Gabès, which forms the western part of Africa's Gulf of Sidra. Most of this greater gulf forms the main coast of Libya including the city of Sirte which shares its root name. The country's geographic coordinates are . Tunisia occupies an area of 163,610 square kilometres, of which 8,250 are water. The principal and reliable rivers rise in the north of the country with a few notable exceptions from north-east Algeria and flow through the northern plain where sufficient rainfall supports diverse plant cover and irrigated agriculture.

Geographic Coordinates
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

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 subt ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot-summer Mediterranean Climate
A Mediterranean climate (also called a dry summer temperate climate ''Cs'') is a temperate climate sub-type, generally characterized by warm, dry summers and mild, fairly wet winters; these weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. This climate type's name is in reference to the coastal regions of the Mediterranean Sea within the Mediterranean Basin, where this climate type is most prevalent. The "original" Mediterranean zone is a massive area, its western region beginning with the Iberian Peninsula in southwestern Europe and coastal regions of northern Morocco, extending eastwards across southern Europe, the Balkans, and coastal Northern Africa, before reaching a dead-end at the Levant region's coastline. Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and 4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sidi El Barrak Dam
The Sidi El Barrak Dam is an embankment dam centred northeast of Tabarak and from the Mediterranean Sea on the Oued Zouara River in the Beja Governorate, Tunisia. Constructed between 1994 and 2000, the primary purpose of the dam is water supply. As part of the Sidi el Barrak Development Project water stored in the dam is pumped to the Seyjame Dam, at a rate of annually. This water is supplied to Tunis, Cap Bon and the Sahel including Sfax Sfax (; ar, صفاقس, Ṣafāqis ) is a city in Tunisia, located southeast of Tunis. The city, founded in AD849 on the ruins of Berber Taparura, is the capital of the Sfax Governorate (about 955,421 inhabitants in 2014), and a Mediterrane ... for municipal use along with other agricultural purposes.

Tell Atlas
The Tell Atlas ( ar, الاطلس التلي, Latn, ar, al-ʾaṭlas al-tlī) is a mountain chain over in length, belonging to the Atlas mountain ranges in North Africa, stretching mainly across northern Algeria, with ends in both north-eastern Morocco and north-western Tunisia. The ranges of this system have an average elevations of about and form a natural barrier between the Mediterranean and the Sahara. Its highest summit is the high Lalla Khedidja in the Jurjura Range. Several large cities such as the Algerian capital, Algiers, with ~1,500,000 residents (2005) and Oran with ~770,000 residents (2005) lie at the base of the Tell Atlas. The Algerian city Constantine with approximately 505,000 residents (2005) lies 80 km inland and directly in the mountains at 650 meters in elevation. A number of smaller towns and villages are situated within the Tell; for example, Chiffa is nestled within the Chiffa gorge. Geography The Tell Atlas runs parallel to the Mediterranean ...

Wādi
Wadi ( ar, وَادِي, wādī), alternatively ''wād'' ( ar, وَاد), North African Arabic Oued, is the Arabic term traditionally referring to a valley. In some instances, it may refer to a wet (ephemeral) riverbed that contains water only when heavy rain occurs. Etymology The term ' is very widely found in Arabic toponyms. Some Spanish toponyms are derived from Andalusian Arabic where ' was used to mean a permanent river, for example: Guadalcanal from ''wādī al-qanāl'' ( ar, وَادِي الْقَنَال, "river of refreshment stalls"), Guadalajara from ''wādī al-ḥijārah'' ( ar, وَادِي الْحِجَارَة, "river of stones"), or Guadalquivir, from ''al-wādī al-kabīr'' ( ar, اَلْوَادِي الْكَبِير, "the great river"). General morphology and processes Wadis are located on gently sloping, nearly flat parts of deserts; commonly they begin on the distal portions of alluvial fans and extend to inland sabkhas or dry lakes.

Lake Of Tunis
The Lake of Tunis ( ''Buḥayra Tūnis''; ) is a natural lagoon located between the Tunisian capital city of Tunis and the Gulf of Tunis (Mediterranean Sea). The lake covers a total of 37 square kilometres, in contrast to its size its depth is very shallow. It was once the natural harbour of Tunis. History The Tunis-Carthage connection was very important to the Romans, as it meant control over the fertile hinterland. The Romans therefore built a dam through the lake. The dam is used today as an expressway for automobiles and railway connecting Tunis to the harbour, La Goulette, and the coastal cities of Carthage, Sidi Bou Said, and La Marsa. The northern lake includes the island of Chikly, once home to a Spanish stronghold, and now (since 1993) a nature reserve. The lake continued to aggrade (an increase in land elevation, in this case of the lake bed, due to the deposition of sediment) during the 19th century. French colonial forces traversed the lake with a 10-kilometer l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Tunis

The Gulf of Tunis () is a large Mediterranean bay in north-eastern Tunisia, extending for from Cape Farina in the west to Cape Bon in the east. Tunis, the capital city of Tunisia, lies at the south-western edge of the Gulf, as have a series of settled places over the last three millennia. Djebel Ressas rises to around south of the southern edge of the Gulf. The central part of the gulf, corresponding to the city of Tunis, is favorable to the implementation of a commercial port due to its location of being a well protected area. The famous city of Carthage was built on the gulf shores.
