DRAA, OUED

also spelled Oued Dra, intermittent stream (wadi) of southern Morocco. Rising from two headstreams, Dads and Imini, in the Haut (High) Atlas mountains of central Morocco, it flows southeastward to Tagounit, hence it courses southwestward, forming much of the AlgerianMoroccan frontier, to the Atlantic near Cap Dra. Of its total length of 700 mi (1,100 km), the longest of any Moroccan river, all but the headstreams and upper course are usually dry. Ouarzazate and Zagora are important riverine oases.
