Rivers

Rivers in Iran

Of Iran's major rivers, five flow into the Persian Gulf, these being the Dez, Karkheh, Karoon, Diyala, and Lower Zab Rivers. Three, the Aras, Sefid Rud, and Atrak Rivers, flow into the Caspian Sea. Two others flow into smaller inland basins, namely the Zayanderud and AjiChay.
