OUED, EL-

town, largest of the Souf Oases in northeastern Algeria. It lies 50 miles (80 km) west of the Tunisian border. Surrounded by the sand dunes of the Grand Erg (sand dunes) Oriental, the Souf Oases extend for 25 miles (40 km) northwest to southeast. A river (oued) once flowed to the east, but it was swallowed by the encroaching sands. The town sits in the midst of the oasis and has narrow, winding streets, with cube-shaped buildings of clay-stone topped by cupolas. The houses are clustered, creating the image of a Town of a Thousand Domes, so-called by the French writer-adventuress Isabella Eberhardt (18771904). The town's fortress mosque and use of arcades and arches reflect both Moorish and Roman influence. Date-palm groves are grown in man-made, funnel-shaped craters that are protected from the sand by woven palm walls and are close enough to groundwater to eliminate irrigation. A busy caravan centre, el-Oued exports high-quality dates and is known for its carpets and woven cloth. Its Museum of the Souf contains regional exhibits. Pop. (1987 prelim.) 70,073.
