Rhumel River

From there it meanders through the Constantine plateau, then narrows considerably north of Aïn Smara where it forms an almost complete oxbow before infiltrating, in a SW/NE orientation, the Djebel El Hadjar limestone tables and the Aïn El Bey plateau.

The lower Rhumel (or Oued-el-Kebir) passes through deep gorges in the Numidian mountains and empties into the sea east of the Gulf of Jijel.

Its waters are widely used for irrigation, and the important spa of Ain Fesguia is located towards the head of the valley.

This tributary supplies drinking water to the city of Constantine, which is highly prone to flooding being situated at the confluence of the Boumerzoug and the Rhumel.

[7] Another tributary is the Oued Dekri, near the town of Chelghoum Laïd 50 km southwest of Constantine.
