How has reduced water flow in the Zayandeh River affected Si-o-Se Pol and the surrounding area?

The reduction of water flow in the Zayandeh River has significantly impacted the Si-o-Se Pol and its surrounding environment. Because government officials have redirected the river's water to neighboring provinces like Yazd for industrial and agricultural use, the riverbed surrounding the bridge remains dry for most of the year.1

This depletion has had several notable consequences:

• Environmental and Social Impact: The lack of water has transformed the riverbed into a site for public protest, where tens of thousands have gathered to challenge water distribution policies.1
• Loss of Functionality: While the bridge was historically designed to function as a dam to control water flow, the current paucity of water—a problem expected to be exacerbated by climate change—leaves the area largely desiccated, except during periods when dams are opened to irrigate wheat fields east of Isfahan.1
• Cultural Shift: Although the bridge remains a central social hub for locals and tourists, the absence of a consistent river flow fundamentally alters the landscape that once supported royal boat races and other water-based events.1
