The Ghezel Ozan (Azerbaijani: Qızılözən (Red River), Persian: قزل اوزن / Qezel Owzan) (also spelled Ghezel Ozen) is one of the longest rivers in Iran, originating from the Chehel Cheshmeh Mountains between Saqqez and Divandarreh in Kurdistan Province flowing in northern Iran.
It is one of two tributaries forming the Sefid-Rud river, with the Shahrood. The Sefīd-Rūd is a major river and tributary of the Caspian Sea. Its catchment area is about 48,600 km2 (18,800 sq mi).
At Rudbar in the southwestern Alborz, the Ghezel Ozan joins the Shah Rud−Shahrood river to form the Sefīd-Rūd river (meaning White River in Persian). Then the Sefid-Rud flows northwards in Gilan Province, through the Alborz range to the Caspian Sea.
Nomenclature
Sometimes the Ghezel Ozan and the Sefīd-Rūd are considered a single river, and the words "Ghezel Ozan" and "Sefid-Rud" are used synonymously for the entire river that flows from the Zagros Mountains in Kordestan Province to the Caspian Sea.[1]
