Bodele

Bodele

 

a depression in the Southern Sahara (Sudan); part of the Lake Chad depression. Maximum elevation, 155 m. The Bodele is covered with salt marshes and sand. Rivers, which are periodically or temporarily filled with water after heavy rains, run from the slopes of the Tibesti and Ennedi highlands and flow into the Bodele, as does Wadi al-Ghazal, which is fed underground by Lake Chad. The Bodele has significant reserves of fresh ground waters and several oases.

Peculiarly, over half of this dust comes from just one place; the Bodele Valley.
By using pairs of high-resolution optical satellite images taken at differing times, the authors monitored dune migration in the Bodele depression of northern Chad over time intervals of 1 month to 6.
From this, pixel-by-pixel estimates of sand flux were generated, allowing the authors to confirm that the Bodele contains some of the world's fastest moving dunes.
The images indicate that more than half of that dust originates from the Bodele depression, a now-dry basin on the southern edge of the Sahara that in wetter times held a body of water the size of Lake Erie.
One of the most prolific spawning grounds for dust today is the Bodele depression, a low-lying area that was once part of Lake Chad.
