Ghezel Ozan
river in Iran
The Ghezel Ozan (South Azerbaijani: قیزیل اؤزن (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 flows through Kurdistan Province, Zanjan Province, East Azerbaijan Province, Ardabil Province, and Gilan Province.
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).
Course
The Ghezel Ozan headwaters are in the Zagros Mountains, in a region near Divan Darreh in Kurdistan Province. It runs northeastwards through Miyaneh County in East Azarbaijan and then Khalkhal County in Ardabil Province and then Zanjan County and Tarom County in Zanjan Province eastwards through the Alborz mountain range in Gilan Province.
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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Ghezel Ozan”, the useful work is to connect “river in Iran” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 27, 2026. The linked authority identifier is Q18520774. Authority coordinates are 35.693, 46.775. 2 of 2 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
