Arabeya Valley, 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.

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.

[7] Arabeya Valley intersects with several national roads as it crosses the Boumerdès in the Khachna Mountains.
