The Zayandeh River Basin is located in central Iran and is known for its significant role in the region's agriculture and water supply. The basin is primarily fed by the Zayandeh River, which originates from the Zardkuh mountain range and flows through the city of Isfahan before eventually drying up in the Gavkhouni Wetland. This basin covers an area of approximately 40,000 square kilometers and supports various ecosystems and communities. The river's water is crucial for irrigation, drinking, and industrial use, making the management of this resource vital for the local population and economy.
