Environment Of Senegal
Senegal is a coastal West African nation located 14 degrees north of the equator and 14 degrees west of the Prime Meridian. The country's total area is 196,190 km2 of which 192,000 km2 is land and 4,190 km2 is water. 70% of the population of Senegal lives in the Coastal Region. Because most of Senegal's population is on the coast, climate change is expected to displace larger parts of the population. Physical features Senegal is bordered to the west by the North Atlantic Ocean. On land, the nation's longest border is with Mauritania to the north, an 813 km border along the Senegal River. To the east is the 419 km border with Mali. In the southeast is Guinea (330 km border) and to the south-southwest is Guinea-Bissau (338 km), both borders running along the Casamance River. Senegal is one of only a handful of countries to have a near-enclave within its borders—the small nation of the Gambia in the interior, which has a 740 km ...

SRTM
The Shuttle Radar Topography Mission (SRTM) is an international research effort that obtained digital elevation models on a near-global scale from 56°S to 60°N, to generate the most complete high-resolution digital topographic database of Earth prior to the release of the ASTER GDEM in 2009. SRTM consisted of a specially modified radar system that flew on board the Space Shuttle Endeavour during the 11-day STS-99 mission in February 2000. The radar system was based on the older '' Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar'' (SIR-C/X-SAR), previously used on the Shuttle in 1994. To acquire topographic data, the SRTM payload was outfitted with two radar antennas. One antenna was located in the Shuttle's payload bay, the other – a critical change from the SIR-C/X-SAR, allowing single-pass interferometry – on the end of a 60-meter (200-foot) mast that extended from the payload bay once the Shuttle was in space. The technique employed is known as interferomet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepen Diakha
Nepen Diakha is a locality situated in the Kédougou Region, Senegal. The highest point of the country is located 2.7 km southeast of Nepen Diakha on Baunez ridge defining the border with Guinea.

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat 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 instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Dakar
Dakar ( ; ; wo, Ndakaaru) (from daqaar ''tamarind''), is the capital and largest city of Senegal. The city of Dakar proper has a population of 1,030,594, whereas the population of the Dakar metropolitan area is estimated at 3.94 million in 2021. The area around Dakar was settled in the 15th century. The Portuguese established a presence on the island of Gorée off the coast of Cap-Vert and used it as a base for the Atlantic slave trade. France took over the island in 1677. Following the abolition of the slave trade and French annexation of the mainland area in the 19th century, Dakar grew into a major regional port and a major city of the French colonial empire. In 1902, Dakar replaced Saint-Louis as the capital of French West Africa. From 1959 to 1960, Dakar was the capital of the short-lived Mali Federation. In 1960, it became the capital of the independent Republic of Senegal. History The Cap-Vert peninsula was settled no later than the 15th century, by the Lebu peop ...

Lake Retba
Lac Rose (meaning Pink Lake) lies north of the Cap Vert peninsula of Senegal, some 30 km (18 miles) north-east of the capital, Dakar, in northwest Africa. It is named for its pink waters caused by ''Dunaliella salina'' algae and is known for its high salt content, up to 40% in some areas. Description The lake is separated from the Atlantic Ocean only by a narrow corridor of dunes, and is named for its pink waters, which are caused by ''Dunaliella salina'' algae. The algae produce a red pigment to help them absorb sunlight, which gives them energy to create ATP. The color is particularly visible during the dry season (from November to May) and less visible during the rainy season (June to October). Magenta coloured samphire bushes flourish in the lake’s white sandbanks; the sand dunes are terra-cotta-coloured. Salt The lake is known for its high salt content (up to 40% in some areas), which is mainly due to the ingress of seawater and its subsequent evaporation. Like t ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...

Territorial Waters
The term territorial waters is sometimes used informally to refer to any area of water over which a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf. In a narrower sense, the term is used as a synonym for the territorial sea. Baseline Normally, the baseline from which the territorial sea is measured is the low-water line along the coast as marked on large-scale charts officially recognized by the coastal state. This is either the low-water mark closest to the shore, or alternatively it may be an unlimited distance from permanently exposed land, provided that some portion of elevations exposed at low tide but covered at high tide (like mud flats) is within of permanently exposed land. Straight baselines can alternatively be defined connecting fringing islands along a coast, across the mouths of rivers, or with certain restrictions across the mou ...

Gambia River
The Gambia River (formerly known as the River Gambra) is a major river in West Africa, running from the Fouta Djallon plateau in north Guinea westward through Senegal and The Gambia to the Atlantic Ocean at the city of Banjul. It is navigable for about half that length. The river is strongly associated with The Gambia, the smallest country in mainland Africa, which occupies the downstream half of the river and its two banks. Geography The Gambia River runs a total length of . From the Fouta Djallon, it runs northwest into the Tambacounda Region of Senegal, where it flows through the Parc National du Niokolo Koba, then is joined by the Nieri Ko and and passing through the Barrakunda Falls before entering the Gambia at Koina. At this point, the river runs generally west, but in a meandering course with a number of oxbows, and about from its mouth it gradually widens, to over wide where it meets the sea. Crossings There are several bridges crossing the river. The largest an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
