Tugas Kepariwisataan 11 The Nile River

The Nile River is the longest river in the world. Its length is around 4,180 miles. It flows through Uganda, Sudan and Egypt. It has two main, they are the Blue Nile and the White Nile. The white Nile starts in the Great Lakes region of central Africa. The flow rate of the Bahr al Jebal at Mongalla, Sudan is almost constant throughout the year and averages 1,048 m3/s. After Mongalla, the Bahr Al Jabal enters the enormous swamps of the Sudd region of Sudan. More than half of the Nile's water is lost in this swamp to evaporation and transpiration. The average flow rate of the White Nile at the tails of the swamps is about 510 m3/s. From here it soon meets with the Sobat River at Malakal. On an annual basis the White Nile upstream of Malakal contributes about 15% of the total outflow of the Nile River.
The Blue Nile begins at Lake Tana in Ethiopia. these two rivers meet near Khartoum the capital city of Sudan. The Blue Nile contributes approximately 80-90% of the Nile River discharge. The flow of the Blue Nile varies considerably over its yearly cycle and is the main contribution to the large natural variation of the Nile flow. During the wet season the peak flow of the Blue Nile will often exceed 5,663 m3/s (200,000 cu ft/s) in late August (a difference of a factor of 50). During the dry season the natural discharge of the Blue Nile can be as low as 113 m3/s (4,000 cu ft/s), although upstream dams regulate the flow of the river.
There is another shorter tributary. It’s the Albarah river, or also known as the Black Nile. 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.
