The Bayuda Desert, located at 18°N 33°E, is in the eastern region of the Sahara Desert, spanning approximately 100,000 km² of NE Sudan north of Omdurman and south of Korti, embraced by the great bend of the Nile in the N, E and S and limited by the Wadi Muqaddam in the W. The north to south aligned Wadi Abu Dom divides the Bayuda Desert into the eastern Bayuda Volcanic Field and the western ochre-coloured sand-sheets scattered with rocky outcrop.
