Dust by Senegal River and Cap-Vert Peninsula, Senegal

May 26th, 2013 Category: Dust Storms, Rivers

West Africa – May 25th, 2013

Dust from the Sahara Desert blows westward off the coast of West Africa. The dust is thickest around the border between Mauritania (above) and Senegal (below), with plumes visible just north of the Senegal River (center) and the Cap-Vert peninsula, a rocky promontory extending west from the main sandy areas of Senegal on which the capital city of Dakar is located.

Mauritania and Senegal - December 26th, 2010

The dry, tan of the Sahara Desert in Mauritania turns greener and more vegetated at the bottom of this image, in Senegal. Visible roughly at the center of the coastline is the Senegal River, which marks the border between Mauritania and Senegal.

In the upper left quadrant, one can observe the Bay of Arguin, green with algal growth, while in the middle is visible the bulls-eye shaped Richat Structure. In the lower left quadrant, the greenish color offshore is due to sediments from the Geba River in Guinea-Bissau.

Mauritania and Senegal - December 16th, 2009

The Senegal River, flowing more or less horizontally across the image, marks the border between Mauritania (above) and Senegal (below). On a vertical axis near the image center is a lake whose waters appear green: the Lac de Guiers.

The lake is located in northern Senegal, south of the city of Richard-Toll and in the Louga and Saint-Louis regions. It is a chief source of fresh water for the city of Dakar, hundreds of kilometers to the south-west, through underground pipes.

It is about 35 kilometers long and 8 kilometers wide, and is supplied by the Ferlo or Bounoum River, which flows north into its southern end from Fouta in the rainy season. Water used to flow out to the Senegal River north through the Portuguese River, but this has been replaced by a straight canal to Richard-Toll. A dam was built in 1916 to prevent saltwater flowing in from Taoué River and the Senegal River Delta.

The shores are mostly fertile. The north shore and surrounding area have been converted to a large sugar-growing region irrigated with water from the lake. Lac de Guiers is also designated an Important Bird Area by BirdLife International.

Mouth of Senegal River by Saint Louis

The Senegal River is a 1790 km long river in West Africa that forms the border between Senegal (below) and Mauritania (above). It is formed by the confluence of the Semefé (Bakoy) and Bafing Rivers at Bafoulabé.

From Bafoulabé the river flows west and then north through the spectacular Talari Gorges near Galougo and over the Gouina Falls, then flows more gently past Kayes and through semi-arid land along the northern border of Senegal to the Atlantic.

Approaching its mouth, the Senegal passes through Biffeche and the island on which the city of Saint Louis is located, then turns south. Around Saint Louis, there are marshes – flood basins that form during the rainy season when the river overflows into the countryside, creating ponds and stretches of mangroves that attract birds like flamingos and pelicans.

By the coast and Saint Louis, the Senegal River is separated from the Atlantic Ocean by a thin strip of sand called the Langue de Barbarie. The entire strip stretches 600km from Nouadhibou in Mauritania to Saint-Louis, of which a 25km section separates the Senegal River from the Atlantic Ocean. Its vegetation mainly consists of Filao trees, propagated to prevent soil erosion in sandy and salty soils.

Senegal River, border of Senegal and Mauritania - November 26th, 2008

Creating a visible green contrast with the surrounding desert sands, the Senegal River flows through western Africa and into the Atlantic Ocean.

It is 1790 km long river and forms the border between Senegal and Mauritania.

The Senegal is separated from the Atlantic Ocean by a thin strip of sand called the Langue de Barbarie before it pours into the ocean itself.

Near its mouth is the island city of Saint Louis.

The Senegal River has a drainage basin of 483,181 km² and an estimated annual discharge of 8 million km³.

In our image, some sections of the river, particularly those farther inland, appear light tan due to sediments. Other sections, however, especially those nearest the coast, appear green, perhaps due to the build-up of algae.
