Dams And Reservoirs In Ethiopia
Ethiopia is called the ''water tower'' of Africa due to its combination of mountainous areas with a comparatively large share of water resources in Africa. Only a fraction of this potential has been harnessed so far, 1% at the beginning of the 21st century. In order to become the powerhouse of Africa, Ethiopia is actively exploiting its water resources by building dams, reservoirs, irrigation and diversion canals and hydropower stations. The benefits of the dams are not only limited to hydropower. Many dams are multi-purpose dams that are also designed to provide water for irrigation, drinking water and flood control. However, hydropower is expected to be the main benefit of the dams. List of dams and reservoirs List with an emphasis on construction-related informations. Weighing the benefits and costs of large dams is far from easy. The following sections describe the impacts of the dams in more detail as objectively as possible, in order to provide a basis for such an asses ...

Turkana Basin
An '' Acacia'' tree in the Kokiselei river, northern Kenya The greater Turkana Basin in East Africa (mainly northwestern Kenya and southern Ethiopia, smaller parts of eastern Uganda and southeastern South Sudan) determines a large endorheic basin, a drainage basin with no outflow centered around the north-southwards directed Gregory Rift system in Kenya and southern Ethiopia. The deepest point of the basin is the endorheic Lake Turkana, a brackish soda lake with a very high ecological productivity in the Gregory Rift. A narrower definition for the term ''Turkana Basin'' is also in widespread use and means Lake Turkana and its environment within the confines of the Gregory Rift in Kenya and Ethiopia. This includes the lower Omo River valley in Ethiopia. The Basin in the narrower definition is a site of geological subsidence containing one of the most continuous and temporally well controlled fossil records of the Plio-PleistoceneFeibel, C., 2011, "A Geological History of the ...

Gilgel Gibe River
Gilgel Gibe River (with ''Gilgel'' meaning ''Little'') is a major tributary of the larger Gibe River in southwest Ethiopia in western Oromia Region. It flows in an arc through the south of the Jimma Zone, defining part of the Zone's boundary with that of the Southern Nations, Nationalities, and Peoples' Region as it turns north. It then joins the eastwards flowing Gibe River less than ten miles from its own confluence with the Omo River. Hydroelectric potential Plans to develop the hydroelectric potential of the Gilgel Gibe river were first announced in the 1980s. Construction of the Gilgel Gibe I Power Station started in 1986 and was completed in 2004, after being interrupted in the early 1990s. The plant includes a reservoir of about 0.917 cubic kilometers created by a dam about 40 meters high. The Gilgel Gibe river flows are returned to the natural river bed after having transformed the energy of the water into electricity through a powerplant equipped with three Francis t ...

Gilgel Gibe I
The Gilgel Gibe I Dam is a rock-filled embankment dam on the Gilgel Gibe River in Ethiopia. It is located about northeast of Jimma in Oromia Region. The primary purpose of the dam is hydroelectric power production. The Gilgel Gibe I hydroelectric powerplant has an installed capacity of 184 MW, enough to power over 123,200 households. The dam is long and tall. Construction on the dam began in 1988 but work was halted in 1994. In 1995 construction restarted with a new construction firm. The power station was commissioned in 2004. Water from the dam is diverted through a long tunnel to an underground power station downstream. The waters after power generation are discharged back into the Gilgel Gibe River to flow downstream northwards for roughly 2 km only to enter a long tunnel through a mountain ridge to an underground power station ( Gilgel Gibe II Power Station) at the lower-lying Omo River The Omo River (also called Omo-Bottego) in southern Ethiopia is the largest ...

Great Rift Valley, Ethiopia
The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction. In the past, it was seen as part of a " Great Rift Valley" that ran from Mozambique to Syria. Description The Great Rift Valley lies between the Ethiopian Plateau to the north and the Somalia Plateau to the south. The rift developed as the Nubian and Somali plates began to separate during the Miocene Period along the East African rift system. Rift initiation was asynchronous along the Ethiopian rift valley: deformation began around 18 million years ago at the south end, around 11 million years ago close to the Afar depression and probably around 6-8 million years ago in the central sector. The rift is extending in an ESE-WNW direction at about annually. The Ethiopian rift valley is about wide and bordered on both margins by large, discontinuous normal faults that give rise ...

Genale Dawa VI
Genale is a town founded by Italian colonists in the southeastern Lower Shebelle (Shabeellaha Hoose) region of Italian Somalia. Currently it is called Janaale. History Genale was created in 1924 by a group of settlers from the Italian city of Torino, with the supervision of the Italian governor of the colony. Near the Genale of the colonists and separated by the Shebelle river, soon grew a bigger city populated by Somalis (working as cheap labor force in the plantations): the actual Janaale. After WW2 remained only Janaale, while Genale disappeared when the defeated Italians moved away from Somalia. In 1924 indeed it was started the Italian colonization of the area of Genale, in southern Somalia, forming a group of small and medium-sized farms. Most settlers consisted of old fascist militants of Turin who had followed in this Italian colony the new governor of Somalia, Cesare Maria De Vecchi. The first informal association between farmers, however, arose only in 1928. The main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jubba River
The Jubba River or Juba River ( so, Wabiga Jubba) is a river in southern Somalia which flows through the autonomous region of Jubaland.
