where does the river nile get its water from
Nile The Nile has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile (Amharic: ዓባይ, ʿĀbay[6][7]) begins at Lake Tana in Ethiopia[8] and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.[9]
Blue Nile The Blue Nile (Ge'ez ጥቁር ዓባይ Ṭiqūr ʿĀbbāy (Black Abay) to Ethiopians; Arabic: النيل الأزرق‎; transliterated: an-Nīl al-Azraq) is a river originating at Lake Tana in Ethiopia. With the White Nile, it is one of the two major tributaries of the Nile. The Blue Nile supplies about 80% of the water in the Nile during the rainy season.
Sub-Saharan Africa Since probably 3500Â BCE,[4][5] the Saharan and Sub-Saharan regions of Africa have been separated by the extremely harsh climate of the sparsely populated Sahara, forming an effective barrier interrupted by only the Nile in Sudan, though the Nile was blocked by the river's cataracts. The Sahara pump theory explains how flora and fauna (including Homo sapiens) left Africa to penetrate the Middle East and beyond. African pluvial periods are associated with a Wet Sahara phase, during which larger lakes and more rivers existed.[6]
Nile The source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder, although sources do not agree on which is the longest tributary of the Kagera and hence the most distant source of the Nile itself.[18] It is either the Ruvyironza, which emerges in Bururi Province, Burundi,[19] or the Nyabarongo, which flows from Nyungwe Forest in Rwanda.[20] The two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border.
