Moulouya
The Moulouya basin stretches across the dry country of the eastern Maghreb, enclosed by mountains and high plateaux. Its principal river rises where the Middle and High Atlas meet and flows northeast towards the Mediterranean. To its east, uplands drain through the Oued Za towards the lower Moulouya. Seasonal streams cut across open plains, carrying the scarce rains towards the larger river and leaving long stretches of the landscape dry.
