Omuramba

Omuramba (plural: Omiramba) is the term for ancient river-beds found in the Kalahari Desert of Africa, notably in the North Eastern part of Namibia and North Western part of Botswana. The word is taken from the Herero language. An omuramba provides occasional standing pools of water and more fertility than in the surrounding sand plains. Some specific omiramba are named: Eiseb, Rietfontein, Epukiro, Omatako. They mostly start in the central parts of Namibia and run into the central parts of Botswana.
