Rivers and Lakes of Egypt

The Nile  is a major north-flowing river in northeastern Africa, generally regarded as the longest river in the world. It is 6,650 km (4,130 miles) long. The Nile is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt.[4] In particular, the Nile River provides the primary water resource and so it is the life artery for its downstream countries such as Egypt and Sudan.[5]
The Nile has two major tributaries, the White Nile and Blue Nile. 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 is the source of most of the water and fertile soil. It begins at Lake Tana in Ethiopia at
12°02′09″N 037°15′53″E / 12.03583°N 37.26472°E / 12.03583; 37.26472 and flows into Sudan from the southeast. The two rivers meet near the Sudanese capital of Khartoum.

The northern section of the river flows almost entirely through desert, from Sudan into Egypt, a country whose civilization has 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. The Nile ends in a large delta that empties into the Mediterranean Sea.\
This is a list of rivers in Egypt.
There is only one year-round river in Egypt, the Nile. It has no non-seasonal tributaries for its entire length in Egypt, though it has two further upstream, the Blue Nile and White Nile, which merge in central Sudan.
In the Nile Delta, the river splits into a number of distributaries and lesser channels. In ancient times there were seven distributaries, of which only two are extant today due to silting and flood relief schemes; from east to west, they were:
  • the Pelusiac,
  • the Tanitic,
  • the Mendesian,
  • the Phatnitic (extant; now the Damietta or Damyat),
  • the Sebennytic,
  • the Bolbitinic,
  • the Canopic (extant; now the Rosetta or Rashid).
The Nile is intersected by a number of normally dry tributaries or wadis which traverse the Eastern Desert. The wadis drain run-off rainfall from the mountains along the Egyptian Red Sea coast, though it only rarely reaches the main trunk of the wadis to flow downstream to the Nile. The three principal wadis are:
