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.

The Gezira Scheme and Sennar Dam, Sudan – January 5th, 2010

January 5th, 2010 Category: Image of the day, Lakes, Rivers

Sudan - December 16th, 2009

Sudan - December 16th, 2009

Despite its greenish appearance, the river flowing northward across the left side of this image is the White Nile. Flowing diagonally across the right side is the Blue Nile.

The expansive, green agricultural area between the two rivers are the fields of the Gezira Scheme in Sudan’s Al Jazirah state. The scheme uses an extensive series of canals and ditches to distribute water to farms in the area.

Upon opening the full image and following the Blue Nile southward, the reservoir created by the Sennar Dam can be observed. The dam, located near the town of Sennar, was built in 1925 to provide water for crop irrigation in the Al Jazirah region. It is 3025 meters (9925 feet) long, with a maximum height of 40 meters (130 feet).

Nile River and Lake Nasser in Sudan and Egypt

21.9N 31.3E

October 20th, 2011 Category: Lakes, Rivers

Egypt - October 19th, 2011

Lake Nasser is visible as a bluish green lake with jagged edges in the upper left quadrant of this image. It is a vast reservoir in southern Egypt and northern Sudan. The lake was created as a result of the construction of the Aswan High Dam across the waters of the Nile between 1958 and 1971.

The Nile River can be seen winding its way northward through Sudan and Lake Nasser and into Egypt. On the Egyptian side, it is flanked by a wide green, fertile valley. In Sudan, near the bottom of the image, it is used to irrigate the crops of the Gezira Scheme.

Geographical Features in Countries Around the Red Sea

Countries by Red Sea - October 21st, 2010

This image shows various countries around the Red Sea, in Africa and the Middle East. As one moves southward, the terrain changes from arid desert to more fertile, vegetated green land.

Visible to the north of the Red Sea is part of Saudi Arabia, mountainous near the coast. Moving south and crossing over the sea, one comes to Eritrea, along the coast, and then to Ethiopia, further inland. The tan, sediment-filled lake near the bottom edge is Lake Tana, in the Ethiopian highlands.

In the upper left corner, part of Egypt is visible by Lake Nasser, on the Egypt-Sudan border. The left side of the image belongs mostly to Sudan. The Nile River can be seen on this side of the image. In the lower left quadrant, the convergence of the Blue Nile (right) and the White Nile (left) can be observed, with the irrigated agricultural project of the Gezira Scheme situated between the two rivers.

Lake Nasser and Nile River, Egypt and Sudan

20.8N 30.3E

July 1st, 2010 Category: Lakes, Rivers

Egypt - June 2nd, 2010

Egypt - June 2nd, 2010

Lake Nasser, on the border of Egypt (above) and Sudan (below) in the upper right corner, appears dark silver in color due to sun glint. Several smaller lakes are visible to the west; these are the Toshka Lakes, created by excess waters from Lake Nasser.

While the left side of the image is mostly sandy desert, the Nile River makes its way across the right side of the image in large curves. The river’s waters are used for irrigation in areas such as the Gezira Scheme, a large agricultural zone partially visible in the lower right corner.
