The Shushtar Historical Hydraulic System is a masterpiece of ancient engineering, with roots going back to the Achaemenid period in the 5th century BC, and substantially expanded by the Sassanids in the 3rd century AD. This complex network of dams, underground tunnels, canals, and watermills was designed to divert the flow of the Karun River to agricultural lands. The system irrigated approximately 40,000 hectares, powering mills and protecting settlements from floods. The centerpiece is a series of spectacular waterfalls cascading from tunnels carved into the rock. It is a remarkable testament to the profound understanding of hydrology by the ancient Persians.
