River Chlef
River Chlef is the largest and most significant river in Algeria, spanning approximately 700 kilometers. It originates near the town of Aflo in the Saharan Atlas Mountains and flows into the Mediterranean Sea. The water from this river is primarily utilized for various agricultural purposes; however, its flow is inconsistent. To manage its waters, three main dams have been constructed along the Chlef system.
River Medjerda
This river is shared between Algeria and Tunisia, starting from the northeastern part of Algeria in the Medjerda Mountains. It flows northeastward for about 466 kilometers, ultimately reaching the Gulf of Tunis in the Mediterranean Sea. Currently, it serves as a vital source for agricultural production, having previously been significant for various civilizations that inhabited the region.
