Blue Nile Falls
The Blue Nile Falls is a waterfall on the Blue Nile river in Ethiopia. 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 originally varied 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 Nile, and this isolation has played a role in the evolution of the endemic fauna of the lake. A short distance downstream from the falls sits the first stone bridge constructed in Ethiopia, built at the command of Emperor Susenyos in 1626. According to Manuel de Almeid ...

Blue Nile Falls-03, By CT Snow
Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. It lies between violet and cyan on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments.

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Blue Nile
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 as being between and . 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, 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 and south Ethiopi ...

Amharic
Amharic ( or ; (Amharic: ), ', ) is an Ethiopian Semitic language, which is a subgrouping within the Semitic branch of the Afroasiatic languages. It is spoken as a first language by the Amharas, and also serves as a lingua franca for all other populations residing in major cities and towns of 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. It has over 31,800,000 mother-tongue speakers, with more than 25,100,000 second language speakers. Amharic is the most widely spoken language in Ethiopia, and the second most spoken mother-tongue in Ethiopia (after Oromo). Amharic is also the second largest Semitic language in the world (after Arabic). Amharic is written left-to-right using a system that grew out of the Geʽez script. The segmental writing system in which consonant-vowel sequences are written as units is called an ''abugida'' (). Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Tana
Lake Tana ( am, ጣና ሐይቅ, T’ana ḥāyik’i; previously Tsana) is the largest lake in Ethiopia and the 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 and 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Susenyos Of Ethiopia
Susenyos I ( gez, ሱስንዮስ ; circa 1571-1575 – 17 September 1632), also known as Susenyos the Catholic, was Emperor of Ethiopia from 1606 to 1632, and a member of the Solomonic dynasty. His throne names were Seltan Sagad and Malak Sagad III. He was the son of ''Abeto'' Fasil, as well as the grandson of ''Abeto'' Yakob and the great-grandson of Dawit II. As a result, while some authorities list Susenyos as a member of the Solomonic dynasty, others consider him—rather than his son, Fasilides—as the founder of the Gondar line of the dynasty (which is, however, ultimately a subset of the Solomonic dynasty). The life of Susenyos is known through his chronicle, written by several official writers (''sehafe te’ezaz''). The Jesuits, who were closely associated with Susenyos’s reign, also left numerous documents on their mission in Ethiopia. Manuel de Almeida, a Portuguese Jesuit who lived in Ethiopia during Susenyos' reign, described the emperor as tall with the fe ...

Manuel De Almeida
Manuel de Almeida (sometimes Manoel de Almeida, 1580–1646) was a native of Viseu who entered at an early age into the Society of Jesus and went out as a missionary to India. He is noted to have travelled to Ethiopia and Eritrea and Lake Tana and built a number of churches and monasteries, particularly on the small islands of the lake. In 1622, Almeida was selected by the general of his order as ambassador to the Emperor of Ethiopia, Susenyos. Accompanied by three companions, Almeida left Bassein 28 November of that year for Suakin, and reached Diu two months later; he was delayed at the port of Dhofar from 18 May 1623 to 16 October due to unfavorable winds. At last Almeida departed for Suakin, reaching it 4 December, where he received a pass from the local Pasha to pass through the territories of the Ottoman Empire. He then found passage to Massawa, whence he made his way to Fremona by way of Debarwa (where he met the governor of Tigray, ''Ras'' Keba Krestos), reaching the ...

Lime (mineral)
Lime is a calcium-containing inorganic material composed primarily of oxides and hydroxide, usually calcium oxide and/or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous sulfate. The rocks and minerals from which these materials are deri ...

Afonso Mendes
Father Afonso Mendes (18 June 1579 – 21 June 1659), was a Portuguese Jesuit theologian, and Patriarch of Ethiopia from 1622 to 1634. While E. A.
