Karun is a river located in southwestern Iran. It is one of the longest rivers in the country, flowing for about 720 kilometers. The river originates in the Zagros Mountains and eventually empties into the Shatt al-Arab, which is a waterway formed by the confluence of the Euphrates and Tigris rivers. The Karun is significant for its role in irrigation and agriculture in the region. The river is also known for its hydroelectric power potential, with several dams constructed along its course, including the Karun-3 Dam. These dams help generate electricity and manage water resources. The Karun River is vital for local ecosystems and supports various wildlife species.
