Algeria is home to several important rivers, with the most significant being the Chélif River, which is the longest river in the country. It flows through the northern region, providing water for agriculture and supporting local ecosystems. Other notable rivers include the Mouilah and Tafna, which also contribute to the region's water supply. The rivers in Algeria are vital for irrigation, especially in the arid climate of the country. They help sustain agriculture and provide habitats for various wildlife. Despite their importance, many rivers face challenges such as pollution and reduced water flow due to climate change and human activities.
