River

Weather…

The Zayanderud is the longest watercourse of the central Iranian plateau, covering a distance of about 400 kilometers from its source to its mouth. The river originates in the Zardkuh mountains, within the Chaharmahal and Bakhtiari province. Flowing eastward, it crosses the historical city of Isfahan, which has a population of over one million, before finally emptying into the endorheic salt marsh of the Gavkhouni lake in the desert. The river has immense historical significance, as it enabled the formation of agricultural oases and urban centers in an otherwise highly arid region. In Isfahan, architecturally outstanding bridges from the Safavid era span the river, including the 33-arch Si-o-se-pol and the Khaju Bridge built in the 17th century.
