River as defined
RIVER is defined as a voluminous stream of fresh water flowing either permanently or seasonally in a natural channel into another body of water, e.g. a sea or a lake. Countless bodies of fresh water all over the world qualify as river as far as this definition is concerned but we're going to delimit our discussion to only one river which is the longest
Nile- world's longest river
It is the NILE river. Its name is derived from the Greek word "Nelios" which means river valley. It's the world's longest river. It measures 6,670 kilometers or 4,145 miles long. It is located in Africa. It connects 10 different African nations includingEthiopia, Eritrea, Sudan, Uganda,Tanzania, Kenya, Rwanda, Burundi.Egypt and the Democratic Republic of the Congo. Generally associated with Egypt, only 22% of the entire Nile course runs through it.
The Source of the Nile river
The largest tributary of Lake Victoria is the Kagera river. The Kagera and its tributary the Ruvubu, with its headwaters in Burundi, is now considered to be the true source of the Nile. From here the Nile is measured as the world's longest river.
The Nile dwarfs the Amazon River of South America by 221 kilometers or 138 miles long.
The 2nd longest river in the world
The Amazon River- the 2nd longest river in the world, was measured to be 6,449 kilometers or 4,007 miles long from the Andes mountain stretching the length of W. South America to the Ucayali in Peru above Iquitos. There it flows 3,400 miles to the Atlantic coast of Brazil.
It is interesting to note that the Amazon river is the river with the largest basin and greatest volume of water in the world, draining nearly half of South America. Oceangoing ships can sail up to Iquitos, still a part of the Amazon river, which is 2,300 miles from the sea.
2 main tributaries
The Nile river flows northward from the equator to the Mediterranean sea, draining 1,293,000 square miles. Its 2 main tributaries are the WHITE NILE and the BLUE NILE.
The White Nile
The White Nile which is the main headstream measures 2,200 miles long. It originates from Lake Victoria at Ripon Falls and flows north through Lake Kyoga and the Murchison Falls into Lake Albert, then through N.W. Uganda and into the Sudan.
Lake Victoria, Ripon Falls, Lake Kyoga, Murchison Falls and Lake Albert for guidance of the readers are all located in Uganda.
The Blue Nile
The Blue Nile measures 850 miles long. It flows from 2 springs in the highlands of Ethiopia through Lake Tana, then over a long series of cataracts in the Sudan. During the rainy season its volume increases 4 times that of the White Nile to cause the annual Nile floods.
Because of losses along the way, the White Nile though a lot bigger than the Blue Nile contributes only about 15% to the flow of the combined Nile. The Blue Nile contributes about 85%.
An explorer has reached the source of the Blue Nile in 1770
Record has it that James Bruce, a Scottish Explorer, has reached the source of the Blue Nile in Abyssinia- ancient name of Ethiopia- in 1770 and traced it to its confluence with the White Nile in Khartoum, Sudan in 1771.
The 2 tributaries unite at Khartoum, Sudan
These 2 tributaries unite at Khartoum to form the great river which flows through Egypt. Khartoum with a population of 476,218 is the capital of Sudan. It is a port on the Blue Nile near its junction with the White Nile
Now Egypt's agriculture is dependent on the Aswan Dam
Its delta beginning at Cairo is 120 miles wide. Its principal mouths are Rosetta which is located east of Alexandria and Damietta. The Nile is navigable in certain seasons as far as Lake Albert- except where cataracts make travel impassable.
Before- Egypt's agriculture was dependent on the floods, now the Aswan Dam and barrages control irrigation- besides providing hydroelectricity.
Nile River System: The Nile is a north-flowing river considered the longest river in the world at 6,650 km (4,130 mi) long. It is shared by and benefits eleven countries. The White Nile and Blue Nile are its major tributaries. The White Nile is longer and rises in the Great Lakes region of central Africa, flowing north from Tanzania to South Sudan. The Blue Nile is the source of most of the water and both rivers join near Khartoum, Sudan The northern section of the river flows almost entirely through desert, from Sudan into Egypt. The Nile ends in a large delta that empties into the Mediterranean Sea.
