Ubangui River
The Ubangi River (), also spelled Oubangui, is the largest right-bank tributary of the Congo River in the region of Central Africa. It begins at the confluence of the Mbomou (mean annual discharge 1,350 m3/s) and Uele Rivers (mean annual discharge 1,550 m3/s) and flows west, forming the border between Central African Republic (CAR) and Democratic Republic of the Congo. Subsequently, the Ubangi bends to the southwest and passes through Bangui, the capital of the CAR, after which it flows southforming the border between Democratic Republic of the Congo and Republic of the Congo. The Ubangi finally joins the Congo River at Liranga. The Ubangi's length is about . Its total length with the Uele, its longest tributary, is .

Bangui
Bangui () (or Bangî in Sango, formerly written Bangi in English) is the capital and largest city of the Central African Republic. It was established as a French outpost in 1889 and named after its location on the northern bank of the Ubangi River (french: Oubangui); the Ubangi itself was named from the Bobangi word for the "rapids" located beside the settlement, which marked the end of navigable water north from Brazzaville. The majority of the population of the Central African Republic lives in the western parts of the country, in Bangui and the surrounding area. The city forms an autonomous commune (''commune autonome'') of the Central African Republic which is surrounded by the Ombella-M'Poko prefecture. With an area of , the commune is the smallest high-level administrative division in the country, but the highest in terms of population. it had an estimated population of 889,231. The city consists of eight urban districts (''arrondissements''), 16 groups (''groupement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Head Of State
A head of state (or chief of state) is the public persona who officially embodies a state Foakes, pp. 110–11 " he head of statebeing an embodiment of the State itself or representatitve of its international persona." in its unity and legitimacy. Depending on the country's form of government and separation of powers, the head of state may be a ceremonial figurehead or concurrently the head of government and more (such as the president of the United States, who is also commander-in-chief of the United States Armed Forces). In a parliamentary system, such as the United Kingdom or India, the head of state usually has mostly ceremonial powers, with a separate head of government. However, in some parliamentary systems, like South Africa, there is an executive president that is both head of state and head of government. Likewise, in some parliamentary systems the head of state is not the head of government, but still has significant powers, for example Morocco. In contrast, ...

Interbasin Transfer
Interbasin transfer or transbasin diversion are (often hyphenated) terms used to describe man-made conveyance schemes which move water from one river basin where it is available, to another basin where water is less available or could be utilized better for human development. The purpose of such water resource engineering schemes can be to alleviate water shortages in the receiving basin, to generate electricity, or both. Rarely, as in the case of the Glory River which diverted water from the Tigris to Euphrates River in modern Iraq, interbasin transfers have been undertaken for political purposes. While ancient water supply examples exist, the first modern developments were undertaken in the 19th century in Australia, India and the United States, feeding large cities such as Denver and Los Angeles. Since the 20th century many more similar projects have followed in other countries, including Israel and China, and contributions to the Green Revolution in India and hydropower developm ...

Sahel
The Sahel (; ar, ساحل ' , "coast, shore") is a region in North Africa. It is defined as the ecoclimatic and biogeographic realm of transition between the Sahara to the north and the Sudanian savanna to the south. Having a hot semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The Sahel part of Africa includes – from west to east – parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, Cameroon and Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and Ethiopia. Historically, the western part of the Sahel was sometimes known as the Sudan region (''bilād as-sūdān'' "lands of the Sudan"). This belt was located between the Sahara and the coastal areas of West Africa. There are frequent shortages of food and water due to the dry h ...

Diversion Dam
A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural course. Diversion dams do not generally impound water in a reservoir; instead, the water is diverted into an artificial water course or canal, which may be used for irrigation or return to the river after passing through hydroelectric generators, flow into a different river or be itself dammed forming an onground or groundwater reservoir or a storm drain. An early diversion dam is the Ancient Egyptian Sadd el-Kafara Dam at Wadi Al-Garawi, which was located about twenty five kilometres south of Cairo. Built around 2600 BC for flood control, the structure was 102 metres long at its base and 87 metres wide. It was destroyed by a flood while it was still under construction.Günther Garbrecht: "Wasserspeicher (Talsperren) in der Antike", ''Antike Welt'', 2nd special edition: ''Antiker Wasserbau'' (1986), pp.51-64 (52f.)

Transaqua
The Lake Chad replenishment project is a proposed major water diversion scheme to divert water from the Congo River basin to Lake Chad to prevent it drying up. Various versions have been proposed. Most would involve damming some of the right tributaries of the Congo River and channeling some of the water to Lake Chad via a canal to the Chari River basin. It was first proposed in 1929 by Herman Sörgel as part of his Atlantropa project, as a way to irrigate the Sahara. In the 1960s, Lake Chad began to shrink, and the idea was revived as a solution to that problem. The members of the Lake Chad Basin International Commission are Chad, the Central African Republic, Nigeria, Cameroon and Niger. Concerned by shrinkage of the lake's area from in 1972 to in 2002, they met in January 2002 to discuss the project. Both the ADB and the Islamic Development Bank expressed interest in the project. However, the member states of the Congo-Ubangi-Sangha Basin International Commission (Congo-K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stream Capture
Stream capture, river capture, river piracy or stream piracy is a geomorphological phenomenon occurring when a stream or river drainage system or watershed is diverted from its own bed, and flows instead down the bed of a neighbouring stream. This can happen for several reasons, including: *Tectonic earth movements, where the slope of the land changes, and the stream is tipped out of its former course *Natural damming, such as by a landslide or ice sheet *Erosion, either **Headward erosion of one stream valley upwards into another, or **Lateral erosion of a meander through the higher ground dividing the adjacent streams. **Within an area of karst topography, where streams may ''sink'', or flow underground (a sinking or losing stream) and then reappear in a nearby stream valley *Glacier retreat The additional water flowing down the capturing stream may accelerate erosion and encourage the development of a canyon (gorge). The now-dry valley of the original stream is known as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
