Dez

Dez is a term used in various contexts, most prominently as the name of a river in Iran. The Dez River, or Rūd-e Dez, is a major river in the southwest of Iran, originating in the Zagros Mountains and flowing through the provinces of Lorestan and Khuzestan before joining the Karun River. The river's basin supports agriculture and settlements; it has several dams, including a large reservoir used for irrigation and hydroelectric power. The city of Dezful lies on the river and has a long history that is closely linked to the Dez.

In addition to geographic usage, Dez is also used as a given name or nickname in various cultures, often as a shortened form of Desmond or as an independent name.

The term may appear in other local place names and features in Iran and neighboring regions, but the river and the city are among the best-known associations of the name Dez.
