The Oued Guir ( Arabic وادي قير, DMG Wādī Qīr ) is an approximately 433 km long river in southern Morocco and the Algerian Sahara , whose upper reaches in the Midelt province of the Meknès-Tafilalet region and then flows through the Errachidia province . Around 42 km then lead through the southern tip of the Figuig province in the Oriental region . It is the western of the two main source rivers of the Oued Saoura in the Algerian Sahara. It is believed that the Oued Guir is identical to the ancient Gir river . The stone and rock desert Hammada du Guir to the west of him was named after him.
course
The valley of the Oued Guir has its origin on the north side of the saddle between the Jbel Timjnatine (approx. 2518 m ) and the Jbel Mesrouh (approx. 2719 m ) in the eastern High Atlas and cuts far to the west through several mountain ranges of the Atlas Mountains up to it reached its south side and then with a general south-southeast direction to take the route into the Sahara. It takes up the Oued Bouanane as the most important tributary from the left and north at kilometer 187 . After around 217 km, the river leaves Morocco. About 23 km south of the Algerian border it reaches the Djorf Torba reservoir , about 40 km west of the provincial capital Bechar . This damms the only periodically flowing water of the Oued Guir in front of an elongated threshold to a water surface of about six kilometers in length and just as wide. Below the dam, the river bed cuts 30 km through rock formations until it reaches the sandy desert with the Abadla oasis . From here to the union with the Oued Zousfana to the Oued Saoura near Igli , the Algerian national road 6 accompanies the dry valley on the west side.
