The geomorphological role of episodic rivers based on the example of the Oueds el Mut and el Feija (AntiAtlas Mountains, Morocco)
Summary: The paper discusses the results of a 2001-2005 field investigation into episodic river channels in the southern Antiatlas mountain range. Because of the size of the study area the investigation concerned only a few selected fluvial systems. The characteristics of the channels in the designated areas were based on the qualitative and quantitative properties of the river channels, the erosion and accumulation landforms present as well as on the kind and quantity of rubble and coarse sediments. Five channel types were identified and described. In general terms the role of the episodic streams draining the northern and southern slopes of Djebel Bani varies. Investigation of the channels and tracks of water flow shows that only the largest oueds on the southern slope carry material to the base of Djebel Bani and the sediment in those river channels is better sorted. On the northern slope clastic material is deposited in Oued el Feija. Aeolian activity can clearly be seen on the alluvial fans which form at the ends of smaller oueds as well as within bigger oueds, and yet the aeolian activity does not mask the fluvial forms.
Słowa kluczowe (w języku angielskim): episodic river channels, types of river channel, structure and dynamics of river channels, Antiatlas, Djebel Bani, oued (wadi), episodic river.
