The White Nile ((アラビア語:النيل الأبيض) ') is a river of Africa, one of the two main tributaries of the Nile, the other being the Blue Nile. In the strict meaning, "White Nile" refers to the river formed at Lake No at the confluence of the Bahr al Jabal and Bahr el Ghazal Rivers. In the wider sense, the term ''White Nile'' refers to the approximately of rivers draining from Lake Victoria into the White Nile proper. It may also, depending on the speaker, refer to the headwaters of Lake Victoria. The 19th century search by Europeans for the source of the Nile was mainly focused on the White Nile, which disappeared into the depths of what was then known as 'Darkest Africa'. The White Nile's true source was not discovered until 1937, when the German explorer Dr. Burkhart Waldecker traced it to a stream in Rutovu at the base of Mount Kikizi. When in flood the Sobat tributary carries a large amount of sediment, adding greatly to the White Nile's color. == Headwaters of Lake Victoria == The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder river for Lake Victoria, although sources do not agree on which is the longest tributary of the Kagera and hence the most distant source of the Nile itself. The source of the Nile can be considered to be either the Ruvyironza, which emerges in Bururi Province, Burundi,〔(【引用サイトリンク】 title= Nile River )〕 near Bukirasaz or the Nyabarongo, which flows from Nyungwe Forest in Rwanda. The two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border. The falls are notable because of an event on 28–29 April 1994, when 250,000 Rwandans crossed the bridge at Rusumo Falls into Ngara, Tanzania in 24 hours, in what the United Nations High Commissioner for Refugees called "the largest and fastest refugee exodus in modern times". The Kagera forms part of the Rwanda–Tanzania and Tanzania–Uganda borders before flowing into Lake Victoria. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「White Nile」の詳細全文を読む スポンサード リンク
