Oued Jeneien is a wadi of Taţāwīn, Tunisia. [1] It is also known as Wādī al Janā’in, and Oued Djeneien. [2] [3] in the far south of the country.
Wadi, alternatively wād, is the Arabic term traditionally referring to a valley. In some instances, it may refer to a dry (ephemeral) riverbed that contains water only when heavy rain occurs.
Tataouine Governorate is the southernmost of the twenty-four governorates of Tunisia, the only one to border Algeria and Libya. It is also the largest in covering an area of 38,889 km² and has a population of 149,453, nearly tied for second least-populated with Kebili (156,961) after Tozeur (107,912). The capital is Tataouine.
Tunisia, officially the Republic of Tunisia, is a country in the Maghreb region of North Africa, covering 163,610 square kilometres. Its northernmost point, Cape Angela, is the northernmost point on the African continent. It is bordered by Algeria to the west and southwest, Libya to the southeast, and the Mediterranean Sea to the north and east. Tunisia's population was 11.435 million in 2017. Tunisia's name is derived from its capital city, Tunis, which is located on its northeast coast.
The wadi is at Latitude 31°39'55.47", Longitude: 9°49'10.16" and 273 meters above Sea level. The wadi is an internal stream flowing, and dissipating into the Sahara rather than flowing into the Mediterranean [4] The wadi is near the settlements of Gara M'hamed Ali and Tarfa. [5]
In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earth's surface. Latitude is an angle which ranges from 0° at the Equator to 90° at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth. On its own, the term latitude should be taken to be the geodetic latitude as defined below. Briefly, geodetic latitude at a point is the angle formed by the vector perpendicular to the ellipsoidal surface from that point, and the equatorial plane. Also defined are six auxiliary latitudes which are used in special applications.
Longitude, is a geographic coordinate that specifies the east–west position of a point on the Earth's surface, or the surface of a celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians connect points with the same longitude. By convention, one of these, the Prime Meridian, which passes through the Royal Observatory, Greenwich, England, was allocated the position of 0° longitude. The longitude of other places is measured as the angle east or west from the Prime Meridian, ranging from 0° at the Prime Meridian to +180° eastward and −180° westward. Specifically, it is the angle between a plane through the Prime Meridian and a plane through both poles and the location in question.
Mean sea level (MSL) is an average level of the surface of one or more of Earth's oceans from which heights such as elevation may be measured. MSL is a type of vertical datum – a standardised geodetic datum – that is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location.
