[1] Al-Hamiz Valley originates in the northern part of Deux Bassins municipality, located in Médéa Province.

Its source lies at a direct linear distance of 33.68 km (20.93 miles) from its mouth on the Mediterranean coast within Algiers Province.

The river’s source is situated in the Tell Atlas and Titteri Mountains, which span the central regions of Médéa, Bouira, Blida, and Boumerdès provinces.

The course of the river serves as a natural boundary between these two municipalities, extending to its outlet in the Mediterranean Sea along the Algiers coastline.
