Blue Nile River
The Blue Nile is a river originating at Lake Tana in Ethiopia. It travels for approximately through Ethiopia and Sudan. Along with the White Nile, it is one of the two major tributaries of the Nile and supplies about 85.6% of the water to the Nile during the rainy season. Course The distance of the river from its source to its confluence has been variously reported between . This uncertainty might result from the fact that the river flows through a series of virtually impenetrable gorges cut in the Ethiopian Highlands to a depth of some . According to materials published by the Central Statistical Agency, an Ethiopian government agency, the Blue Nile has a total length of , of which are inside Ethiopia. In Ethiopia The Blue Nile originates at Lake Tana in Ethiopia (where it is called the Abay River). The river flows generally south before entering a canyon about long, about from Lake Tana, which is a tremendous obstacle for travel and communication between north an ...

Lake Tana
Lake Tana (; previously transcribed Tsana) is the largest lake in Ethiopia and a source of the Blue Nile. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately long and wide, with a maximum depth of , and an elevation of . Lake Tana is fed by the Gilgel Abay, Reb River, Reb and Gumara River, Gumara rivers. Its surface area ranges from , depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls (Tis Abbai) and hydro-power station. In 2015, the Lake Tana region was nominated as a UNESCO Biosphere Reserve recognizing its national and international natural and cultural importance. Overview Lake Tana was formed by volcanic activity, blocking the course of inflowing rivers in the early Pleistocene epoch, about 5 million years ago. The lake was originally much larger than it is today. Seven large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wanchet River
Wanchet River is a river of central Ethiopia, and a tributary of the Jamma River. Along with the Adabay River, it defined the border of the former district of Marra Biete. Its crossing "Aqui afagi" (''Aheya Fajj'', Amharic "destroyer of donkeys") is mentioned in the account of Portuguese explorer Francisco Álvares, who crossed it several times in the first quarter of the 16th century.Huntingford, ''Historical Geography'', pp. 32f, 81 See also *List of rivers of Ethiopia This is a list of streams and rivers in Ethiopia, arranged geographically by drainage basin.

Ethiopia–Sudan Border
The Ethiopia–Sudan border (; ) is a disputed border between the Ethiopia, Federal Republic of Ethiopia and the Sudan, Republic of the Sudan since the 19th century.Ullendorff, Edward. "The Anglo-Ethiopian Treaty of 1902." ''Bulletin of the School of Oriental and African Studies, University of London'', vol. 30, no. 3, 1967, pp. 641–654. ''JSTOR''www.jstor.org/stable/612393 Accessed 15 Jan. 2021. Ethiopia and Sudan share a long boundary of 744 km (462 mi) in length. Though it was not acceptable by the Ethiopian Empire, the Ethio-Sudan colonial border is not clear since it mainly relies on natural landmarks such as mountains, trees, and rivers. One of the most disputed areas is the fertile agricultural region of Al-Fashaga District, al-Fashaga, where Ethiopia claims the land up to the Atbarah River, Atbarah and Tekezé River while Sudan claims the border is further east. History On 15 April 1891, Ethiopian Emperor Menelik II sent a letter to European heads of state w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amharic
Amharic is an Ethio-Semitic language, which is a subgrouping within the Semitic branch of the Afroasiatic languages. It is spoken as a first language by the Amhara people, and also serves as a lingua franca for all other metropolitan populations in Ethiopia. The language serves as the official working language of the Ethiopian federal government, and is also the official or working language of several of Ethiopia's federal regions. In 2020 in Ethiopia, it had over 33.7 million mother-tongue speakers of which 31 million are ethnically Amhara, and more than 25.1 million second language speakers in 2019, making the total number of speakers over 58.8 million. Amharic is the largest, most widely spoken language in Ethiopia, and the most spoken mother-tongue in Ethiopia. Amharic is also the second most widely spoken Semitic language in the world (after Arabic). Amharic is written left-to-right using a system that grew out of the Geʽez script.

Blue Nile Falls
The Blue Nile Falls is a waterfall on the Blue Nile river in West Gojjam, Amhara Region, Ethiopia Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a landlocked country located in the Horn of Africa region of East Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east, Ken .... It is known as Tis Abay in Amharic, meaning 'great smoke'. It is situated on the upper course of the river, about downstream from the town of Bahir Dar and Lake Tana. The falls are one of Ethiopia's best-known tourist attractions. The falls are high, consisting of four streams that vary from a trickle in the dry season to over 400 meters wide in the rainy season. Regulation of Lake Tana now reduces the variation somewhat, and since 2003 a hydro-electric station has taken much of the flow out of the falls except during the rainy season. The Blue Nile Falls isolate the ecology of Lake Tana from the ecology of the rest of the Ni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Statistical Agency
The Central Statistical Agency, also known as the Ethiopian Statistical Service (ESS; Amharic: የኢትዮጵያ ስታቲስቲክስ አገልግሎት), is an Ethiopian government agency designated to provide all surveys and censuses for that country used to monitor economic and social growth, as well as to act as an official training center in that field. It is part of the Ethiopian Ministry of Finance and Economic Development. The Director General of the ESS is Beker Shale (Ph.D.).

Ethiopian Highlands
The Ethiopian Highlands (also called the Abyssinian Highlands) is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the "Roof of Africa" due to its height and large area. It is the only country in the region with such a high elevated surface. This elevated surface is bisected diagonally by the Great East African Rift System which extends from Syria to Mozambique across the East African Lakes. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrean Highlands, Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval and Early modern period, early modern state, whence the coffee plant was exported to the Arabian Peninsula. The land of the former kingdom is mountainou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confluence
In geography, a confluence (also ''conflux'') occurs where two or more watercourses join to form a single channel (geography), channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the river source, source of a river of a new name (such as the confluence of the Monongahela River, Monongahela and Allegheny River, Allegheny rivers, forming the Ohio River); or where two separated channels of a river (forming a river island) rejoin downstream from their point of separation. Scientific study Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern [downstream o ...

River Source
The headwater of a river or stream is the geographical point of its beginning, specifically where surface runoff water begins to accumulate into a flowing channel of water. A river or stream into which one or many tributary rivers or streams flows has many headwaters, these being all of the individual headwaters of its tributaries. Each headwater is one of the river or stream's sources, as it is the place where surface runoffs from rainwater, meltwater, or spring water begin accumulating into a more substantial and consistent flow that becomes a Strahler number, first-order tributary of that river or stream. The tributary with the longest channel (geography), channel of all the tributaries to a river or stream, such length measured from that tributary's headwater to its mouth where it discharges into the river or stream, is the main stem of the river or stream in question. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Season
The wet season (sometimes called the rainy season or monsoon season) is the time of year when most of a region's average annual rainfall occurs. Generally, the season lasts at least one month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M.
