In page Casablanca:

"

The only watercourse in Casablanca is oued Bouskoura,[4] a small seasonal creek that until 1912 reached the Atlantic Ocean near the actual port. Most of oued Bouskoura's bed has been covered due to urbanization and only the part south of El Jadida road can now be seen. The closest permanent river to Casablanca is Oum Rabia, 70 km (43.50 mi) to the south-east.[citation needed]
