The main water supplier for the basin is Lake Victoria, located in the Great Rift Valley. [4] About 238 million people live within the Nile basin, 172 million of those inhabit rural localities. [5] In the southwestern part of the basin in South Sudan near the watershed with Congo Basin relief is made up a single large pediplain. [6]
The Nile [b] (also known as the Nile River or River Nile) is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea . The Nile is the longest river in Africa.
The first indications of the rise of the river could be seen at the first of the cataracts of the Nile (at Aswan) as early as the beginning of June, and a steady increase went on until the middle of July, when the increase of water became very great. The Nile continued to rise until the beginning of September, when the level remained stationary ...
In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
A nilometer is a structure for measuring the Nile River's clarity and water level during the annual flood season in Egypt. [1] There were three main types of nilometers, calibrated in Egyptian cubits: (1) a vertical column, (2) a corridor stairway of steps leading down to the Nile, and (3) a deep well with a culvert. [1]
Egyptian civilization has sustained itself utilizing water management and agriculture for some 5,000 years in the Nile River valley. The Egyptians practiced basin irrigation, a form of water management adapted to the natural rise and fall of the Nile River. Since around 3000 BCE, the Egyptians constructed earthen banks to form flood basins of ...
The Nile runs through Sudan, South Sudan, Burundi, Rwanda, Democratic Republic of the Congo, Tanzania, Kenya, Uganda, Ethiopia, and Egypt and is considered to be the longest river in the world. The Nile is the only significant source of water in North Africa and 40% of Africa’s population lives in the Nile River Basin. [3]
The Nile delta is especially vulnerable to sea level rise. Egypt's Mediterranean coastline experiences significant loss of land to the sea, in some places amounting to 90 m (100 yd) a year. The low-lying Nile Delta area in particular is vulnerable to sea level rise associated with global warming. [22]
