The Gibe River (also Great Gibe River) is by far the largest tributary of the Omo River in southwestern Ethiopia and flows generally south-southeast. The confluence of the Gibe River 8°19′N37°28′E / 8.317°N 37.467°E with the smaller Wabe River form the Omo River. The whole drainage basin is sometimes referred to as the Omo-Gibe River Basin with the Gibe and the Omo draining the (respectively) upper and lower reaches.
In common with most of Ethiopia's rivers, the Gibe is not navigable.
The Gibe rises at an elevation of more than 2,000 m north of Bila town, west of the Chomen swamp from Gudeya Bila woreda, which is located in the East Welega Zone, Oromia Region. The river then flows generally to the southeast towards its confluence with the Wabe River. Its tributaries include the Amara, Alanga, and Gilgel Gibe rivers. The southern drainage area of the Gibe includes the Gibe region, site of a number of historic kingdoms of the Oromo and the Sidama people. The Gibe River terminates at an elevation of 1060 m, at its confluence with the Wabe River, thus forming the Omo River.
Although its banks and watershed have been inhabited since time since prehistoric times, the Gabe is first mentioned in the Royal Chronicle of Emperor Sarsa Dengel, who campaigned in the north of the region in 1566. [1] The first recorded European to see the Gibe was the Portuguese Jesuit missionary António Fernandes, who crossed the Gibe in 1613 as he left Ennarea and entered Janjero. Fernandes later described the Gibe as carrying "more Water than the Nile". [2] The Gibe would not be visited again by Europeans until the 19th century, so Fernandes' account remained authoritative and was preferred over information obtained from native travellers. [3]
The Kura is an east-flowing river south of the Greater Caucasus Mountains which drains the southern slopes of the Greater Caucasus east into the Caspian Sea. It also drains the north side of the Lesser Caucasus while its main tributary, the Aras, drains the south side of those mountains. Starting in northeastern Turkey, it flows through Turkey to Georgia, then to Azerbaijan, where it receives the Aras as a right tributary, and enters the Caspian Sea at Neftçala. The total length of the river is 1,515 kilometres (941 mi).
The Omo River in southern Ethiopia is the largest Ethiopian river outside the Nile Basin. Its course is entirely contained within the boundaries of Ethiopia, and it empties into Lake Turkana on the border with Kenya. The river is the principal stream of an endorheic drainage basin, the Turkana Basin.
The Mursi are a Surmic ethnic group in Ethiopia. They principally reside in the Debub Omo Zone of the Southern Nations, Nationalities, and People's Region, close to the border with South Sudan. According to the 2007 national census, there are 11,500 Mursi, 848 of whom live in urban areas; of the total number, 92.25% live in the Southern Nations, Nationalities, and People's Region (SNNPR).
The Gibe region was a historic region in modern southwestern Ethiopia, to the west of the Gibe and Omo Rivers, and north of the Gojeb. It was the location of the former Oromo and Sidama kingdoms of Gera, Gomma, Garo, Gumma, Jimma, and Limmu-Ennarea.
The Kingdom of Garo, also known as Bosha after its ruling dynasty, was an Oromo-Sidama kingdom in the Horn of Africa. Established by the Sidama people, it was situated on the periphery of the Gibe region of Ethiopia.
The Kingdom of Yamma was a small kingdom located in what is now Ethiopia. It lay in the angle formed by the Omo and the Jimma Gibe Rivers; to the west lay the Kingdom of Jimma and to the south the Kingdom of Garo. Three mountains — Mount Bor Ama, Mount Azulu and Mount Toba — all distinguish the location of the former kingdom.
The Kingdom of Kaffa was a kingdom located in what is now Ethiopia from 1390 to 1897, with its first capital at Bonga. The Gojeb River formed its northern border, beyond which lay the Gibe kingdoms; to the east the territory of the Konta and Kullo peoples lay between Kaffa and the Omo River; to the south numerous subgroups of the Gimira people, and to the west lay the Majangir people. The native language, also known as Kaffa, is one of the Omotic group of languages.
The Squamish River is a short but very large river in the Canadian province of British Columbia. Its drainage basin is 3,328 square kilometres (1,285 sq mi) in size. The total length of the Squamish River is approximately 80 kilometres (50 mi).
The Bosut is a river in the Syrmia region of eastern Croatia and northwestern Serbia, a 186 km long left tributary of the Sava river. Slow and meandering, it originates from the confluence of Biđ and Berava rivers south of the city of Vinkovci, the only major city on its course, and then turns southeast. Near Lipovac it receives its major tributary Spačva, and then enters Serbia near Batrovci. In its lower course, Bosut flows through a forested area in the Spačva region. The river is generally known for its abundance of fish.
Mareka Gena was one of the 77 woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Semien Omo Zone, Mareka Gena was a triangle-shaped area located south of the confluence of the Omo River and its east-flowing tributary the Gojeb River, bordered on the southeast by Loma Bosa, on the west by Isara Tocha, and on the north by the Oromia Region. Towns in Mareka Gena included Wacca and Weldehane. Mareka Gena was divided for Gena Bosa and Mareka woredas.
Gilgel Gibe River 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.
Boulder Creek is a 7.9-mile-long (13 km) stream tributary of the San Lorenzo River in the U.S. state of California. Its drainage basin consists of approximately 11.3 square miles (29.3 km2) of Santa Cruz County. Its main stem begins high in the Santa Cruz Mountains in Big Basin Redwoods State Park. It flows generally south, through the Park and unincorporated community of Boulder Creek, before finally emptying into the San Lorenzo River in the community's downtown.
António Fernandes was a Portuguese Jesuit missionary.
In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams as part of drainage basins. This is the topographic region from which a stream receives runoff, throughflow, and its saturated equivalent, groundwater flow. The number, size, and shape of the drainage basins varies and the larger and more detailed the topographic map, the more information is available.
Wabe River is a west-southwest flowing river of south-central Ethiopia, entirely confined within the reaches of Gurage Zone of the Southern Nations, Nationalities, and Peoples' Region.
The Gilgel Gibe III Dam is a 250m high roller-compacted concrete dam with an associated hydroelectric power plant on the Omo River in Ethiopia. It is located about 62 km (39 mi) west of Sodo in the Southern Nations, Nationalities, and Peoples' Region. Once fully commissioned, it will be the third largest hydroelectric plant in Africa with a power output of about 1870 Megawatt (MW), thus more than doubling total installed capacity in Ethiopia from its 2007 level of 814 MW. The Gibe III dam is part of the Gibe cascade, a series of dams including the existing Gibe I dam and Gibe II power station as well as the planned Gibe IV and Gibe V dams. The existing dams are owned and operated by the state-owned Ethiopian Electric Power, which is also the client for the Gibe III Dam.
The Vellar River is a river in the Indian state of Tamil Nadu. It originates in the Kalrayan Hills, and flows generally eastward through Salem, Perambalur, and Cuddalore districts, before flowing into the Bay of Bengal near Parangipettai.
