Convergence of White and Blue Nile Rivers Near Khartoum, Sudan

15.5N 32.5E

Sudan - December 31st, 2011

The Nile is a major north-flowing river in northeastern Africa, generally regarded as the longest river in the world, at 6,650 km (4,130 miles) long. It runs through the ten countries of Sudan, South Sudan, Burundi, Rwanda, Democratic Republic of the Congo, Tanzania, Kenya, Ethiopia, Uganda and Egypt.

This image focuses on the part of the Nile in Sudan. It enters the country below Renk as the White Nile, and flows north to Khartoum, where it meets the Blue Nile. The area between the two rivers, visible in the lower right quadrant, is a large tract of irrigated land known as the Gezira Scheme. The course of the Nile in Sudan is distinctive. It flows over six groups of cataracts, from the first at Aswan to the sixth at Sabaloka (just north of Khartoum) and then turns to flow southward before again returning to flow north. This is called the Great Bend of the Nile. In the north of Sudan the river enters Lake Nasser (known in Sudan as Lake Nubia), the larger part of which is in Egypt.

Gezira Scheme Between White Nile and Blue Nile Rivers, Sudan

Sudan - December 29th, 2011

Stretching over an area of 3,400 milesĀ² (8,800 kmĀ²) between the While Nile (left) and Blue Nile (right) Rivers is the irrigated land of the Gezira Scheme, one of the largest irrigation projects in the world. The confluence of the two rivers at the city of Khartoum can be observed near the top edge.

The Gezira (which means “island”) is particularly suited to irrigation because the soil slopes away from the Blue Nile and water therefore naturally runs through the irrigation canals by gravity. This network of canals and ditches is 2,700 miles (4,300 km) long. Upon opening the full image, many individual fields can be observed.

Khartoum and Gezira Scheme by Nile River in Sudan – January 9th, 2012

Sudan - January 9th, 2012

Situated near the top edge of this orthorectified wide-swath ASAR image is Khartoum, the capital and largest city of Sudan and of Khartoum State. It is located at the confluence of the White Nile flowing north from Lake Victoria, and the Blue Nile flowing west from Ethiopia. The location where the two Niles meet is known as “al-Mogran”.

Visible just southeast of the confluence of the Blue and White Nile Rivers at Khartoum is the Gezira Scheme, one of the largest irrigation projects in the world. It distributes water from the Blue Nile through canals and ditches to tenant farms lying between the the two rivers. The Gezira is particularly suited to irrigation because the soil slopes away from the Blue Nile and water therefore naturally runs through the irrigation canals by gravity.

Blue and White Nile Rivers Meeting Near Khartoum, Sudan – November 5th, 2011

November 5th, 2011 Category: Image of the day, Rivers

Sudan - November 4th, 2011

The Nile is a major north-flowing river in North Africa, generally regarded as the longest river in the world. It is 6,650 km (4,130 miles) long and runs through ten countries: Sudan, South Sudan, Burundi, Rwanda, Democratic Republic of the Congo, Tanzania, Kenya, Ethiopia, Uganda and Egypt.

The Nile has two major tributaries, the White Nile and Blue Nile. The White Nile 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 starts at Lake Tana in Ethiopia and flows into Sudan from the southeast.

The two rivers meet near the Sudanese capital of Khartoum. Their confluence can be observed northeast of the image center. Below the point where they converge is the Gezira Scheme, an extensive area of irrigated agriculture.

Gezira Scheme Between While and Blue Nile Rivers

Sudan - May 2nd, 2011

True to its name, the White Nile River (left) does have a lighter color than the Blue Nile (right). The two rivers converge near Khartoum, at the top of the full image.

Between the two rivers is the Gezira Scheme, one of the largest irrigation projects in the world. It is centered on the Sudanese state of Al Jazirah.

The Gezira (which means “island”) is particularly suited to irrigation because the soil slopes away from the Blue Nile and water therefore naturally runs through the irrigation canals by gravity. The soil has a high clay content which keeps down losses from seepage.
