The basin supports 2,700 square kilometres of irrigated land, drawing water from various sources, including hydraulic units, wells, qanats, and springs.

History of Zayandeh Rud

The Zayandeh Rud River has played a crucial role not only as a vital water source but also as a witness to human history in the Iranian plateau. Humans have been living along its banks for thousands of years, and evidence of ancient civilizations can be clearly seen in the region. One of the earliest signs of human life along the river was found in a cave site called Qaleh Bozi, located southwest of Isfahan. This cave served as a shelter for Palaeolithic hunter-gatherers (Neanderthals), who used it for seasonal or temporary habitation and left behind stone tools and animal bones.

Throughout history, the Zayandeh Rud River continued to hold great significance in the development of Isfahan. In the 17th century, Sheikh Baha’i, a prominent scholar and adviser to the Safavid dynasty, designed and constructed a complex system of canals known as “Maadi” to distribute the river’s water to the suburbs of Isfahan. This system not only helped in irrigation and agriculture but also contributed to the growth of the city’s population and economy, transforming Isfahan into a thriving urban centre in the heart of the desert. During this period, Safavid-era bridges were built across the river, which remain iconic examples of the era’s architecture.

The water from the Zayandeh Rud River, alongside its role in agriculture and urban development, contributed to making Isfahan one of the most beautiful and vibrant cities in Iran, known for its green landscape and stunning gardens. This river is not just a source of water; it symbolizes the art, culture, and history of Iran over thousands of years.
