What type of river is the oued or wadi found in the valleys of North Africa and Arabia?

Exotic River
Perennial river
Episodic River
Periodic River
Wadi (or oued) is the Arabic term traditionally referring to a valley. In some instances, it may refer to a dry (ephemeral) riverbed that contains water only during times of heavy rain, a so-called episodic river. Periodic / Non-Perennial Rivers only flow during the rainy season. Exotic Rivers rise in humid areas with high rainfall and flow through dry areas.
