The Oued Meraldene or Oued Merabtene, also called Oued Bourdine, is a river of Algeria located in Kabylia within the framework of the Province of Boumerdès.

The Meraldène stream is one of the main tributaries of the Boumerdès River which is a river that finds its mouth in the Mediterranean Sea.

This river takes its source in the heights of the current commune of Beni Amrane in the Khachna Massif which shelters the peak of Bouzegza Mount [ar].

At an altitude of 590 meters above sea level near the villages of Beni Khelifa and Azela, Oued Meraldene is born to take its course on a river bed that juts out into the current town of Thénia.

This area is rich in water resources thus feeds the Oued which then traces its route between the villages of Tabrahimt, Meraldene, Gueddara, Soumâa, Tizouighine before reaching the plateau of the village Louz.

The Meraldene River rises in flood especially during the winter and the Oued becomes impassable and dangerous, and causes floods that spread to the village of Louz beyond which it finds its mouth with the Boumerdès River which springs also from the heights of Beni Amrane and then flows into the Mediterranean.

It is because of the floods and the rising waters of the two Oueds at the level of this mouth that a bridge was built on the National Road No. 5 [ar] to pass the water and not to block road traffic.

Given the profusion of water flowing through Oued Meraldene, a hydraulic dam was built to store part of its flowing water.
