The Karkheh River is a significant waterway located in western Iran. It originates from the Zagros Mountains and flows through the Khuzestan Province, eventually joining the Karun River. The river plays a crucial role in the region's agriculture and irrigation systems. Spanning approximately 400 kilometers, the Karkheh River is vital for local ecosystems and communities. It supports various wildlife and provides water for farming, particularly in the fertile plains of Khuzestan. The river's basin is also important for managing water resources in the area.
