The Zayandeh Rud Basin is a significant river basin located in central Iran. It is primarily known for the Zayandeh Rud River, which flows through the city of Isfahan and is crucial for agriculture and water supply in the region. The basin covers an area of approximately 40,000 square kilometers and supports various ecosystems. The basin's water resources are vital for irrigation, drinking water, and industrial use. However, the region faces challenges such as water scarcity and pollution, largely due to over-extraction and climate change. Efforts are ongoing to manage and conserve the basin's water resources effectively.
