Oueds fonctionnels, oueds fossiles, oueds mythiques et rivières artificielles du Bas-Sahara algérien

Abstract : New researches on Bas-Sahara hydrography have been performed. They show that mythical wadis such as wadi Igharghar from south of the Grand Erg Oriental, wadi Mya close to Ouargla and wadi Rhir do not exist. Among the functional real wadies, those that run from the Saharan Atlas mountains are best known, due to their dams. Those of the M'Zab ridge are still porly studied. Fossil real wadis have been just discovered in the Souf region, upward the Grand Erg Oriental. The only genuine perennial rivers, such as the grand drain, are fed by oasis collature waters and towns rainwater networks.
