Arabeya Valley, (also known as Wadi Arabiya or Wadi Thinia Bani Aisha), is a watercourse originating from the Khachna Mountains of Algeria. It flows through the Kabylia region, eventually draining into Isser River and then into the Mediterranean Sea, passing through the Boumerdès Governorate.
Arabeya Valley channel is characterized by the absence of schist and soil materials in its bed. This feature, shared by this watercourse along with Meraldene River, Boumerdès Valley, and Isser River, allows for the extraction of sand and gravel for use in mortar and concrete preparation. Wadi Arabiya is considered a true corridor, with its width ranging between 5 meters and 600 meters. It gradually slopes from its intersection with Wadi Boumerdès at Mount Bouaârous in the west, heading towards its mouth in Isser River, east of the city of Thénia.
Arabeya Valley runs through one coastal Algerian province.
Arabeya Valley intersects with several other valleys in the Boumerdès along its course through the Khachna Mountains.
Arabeya Valley passes through several dams in the Boumerdès along its course through the Khachna Mountains.
Arabeya Valley intersects with several national roads as it crosses the Boumerdès in the Khachna Mountains.
