[:ja]ルカ・パルミタノ宇宙飛行士がISSから撮影したスーダンの白ナイルです。
白ナイル川は、ビクトリア湖を源流とするアフリカ北東部を流れる河川で、青ナイル川と共にナイル川の支川を形成、ナイル川全体の水量の約20%を占めます。青ナイルよりも白く濁った水の名前から、この支流は「白ナイル」と呼ばれるようになりました。狭義の白ナイルは、南西からのバハル・エル＝ガザル川と南からのバハル・アル＝ジャバル川とが南スーダンで合流して形成されるノ湖から青ナイルと合流するハルツームまでです。広義では源流部のヴィクトリア湖からウガンダ国内を北上し、キオガ湖とアルバート湖を経て、バハル・アル＝ジャバル川を通過する全ての水域を含み、長さは約3,700kmになります。

[Earthview Wonders] No.1181: White Nile in Sudan🇸🇩
Astronaut Luca Parmitano captured from ISS the White Nile in Sudan.
The White Nile formed at Lake Victoria is one of the two main tributaries of the Nile along with the Blue Nile. When in flood, the Sobat River tributary carries a large amount of sediment, adding greatly to the White Nile’s color. In the wider sense, “White Nile” refers to all the stretches of river draining from Lake Victoria through to the merger with the Blue Nile. These higher stretches being named the “Victoria Nile,” the “Albert Nile” and then the “Mountain Nile” or “Bahr-al-Jabal.” “White Nile” may sometimes include the headwaters of Lake Victoria, the most remote of which being 3,700km from the Blue Nile.
The local scenery of the confluence of Blue and White Nile near Khartoum is as follows.
