The Nile is a major north-flowing river in northeastern Africa, generally regarded as the longest river in the world. It is 6,853 km (4,258 miles) long. The Nile is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.
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 begins at Lake Tana in Ethiopia[7] and flows into Sudan from the southeast. The two rivers meet near the Sudanese capital of Khartoum.
The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta and empties into the Mediterranean Sea. Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along riverbanks.
In the ancient Egyptian language, the Nile is called Ḥ'pī or Iteru, meaning "river", represented by the hieroglyphs shown on the left (literally itrw, and 'waters' determinative). In Coptic, the words piaro (Sahidic) or phiaro (Bohairic) meaning "the river" (lit. p(h).iar-o "the.canal-great") come from the same ancient name.
The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the
Latin Nilus and the Ancient Greek Νεῖλος. Beyond that, however, the etymology is disputed.One possible etymology derives it from a Semitic Nahal, meaning "river". The standard English names "White Nile" and "Blue Nile", to refer to the river's source, derive from Arabic names formerly applied only to the Sudanese stretches which meet at Khartoum.
Sources
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.[15] It is either the Ruvyironza, which emerges in Bururi Province, Burundi,[16] or the Nyabarongo, which flows from Nyungwe Forest in Rwanda.[17] The two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border.
The source of Nile from the underwater spring at the neck of Lake Victoria, Jinja.
In 2010, an exploration party[18] went to a place described as the source of the Rukarara tributary,[19] and by hacking a path up steep jungle-choked mountain slopes in the Nyungwe forest found (in the dry season) an appreciable incoming surface flow for many kilometres upstream, and found a new source, giving the Nile a length of 6,758 km (4,199 mi)
Gish Abay is reportedly the place where the "holy water" of the first drops of the Nile develop.
