Gezira Scheme Between White Nile and Blue Nile Rivers, Sudan

14.6N 32.8E

January 17th, 2012 Category: Rivers

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

15.5N 32.5E

January 9th, 2012 Category: Image of the day, Rivers

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.

Gezira Scheme Between While and Blue Nile Rivers

15.5N 32.5E

May 22nd, 2011 Category: 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.

The thumbnail image focuses on the Gezira Scheme, an irrigated agricultural project between the Blue and While Nile Rivers. In the full image, a larger section of the rivers’ courses can be observed as well.

Dahlak Archipelago, Lake Tana and Gezira Scheme, Eastern Africa

November 21st, 2010 Category: Lakes, Rivers

Sudan, Ethiopia and Eritrea - November 9th, 2010

The blue waters of the Red Sea occupy the upper right corner of this image of eastern Africa. In the sea, just off the coast of Eritrea, are the islands of the Dahlak Archipelago.

Moving further inland, Lake Tana can be seen in the Ethiopian highlands. It appears tan in color from sediments. Upon opening the full image, the large Dek Island can be seen in the lake.

While much of the land west and immediately north of the lake appears green and brown in color, it becomes significantly more arid as one moves towards the upper left quadrant, west of the Nile River in Sudan.

The convergence of the Blue Nile (right) and the White Nile (left) Rivers to make the Nile River itself can be observed in the upper left quadrant as well. The irrigated fields between the two rivers up to their point of confluence are part of the agricultural project known as the Gezira Scheme.
