Shushtar historical hydraulic system historical site. Located in Iran's Khuzestan Province. It was registered on UNESCO's list of World Heritage Sites in 2009 and is Iran's 10th cultural heritage site to be registered on the United Nations' list. Shushtar infrastructure included water mills, dams, tunnels, and canals. Gargar Bridge-Dam was built on the watermills and waterfalls. Bolayti canal is situated on the eastern side of the water mills and water falls and functions to supply water from behind the GarGar bridge to the east side of water mills and channel the water in order to prevent damage to the water mills. Dahaneye shahr tunnel (city orifice) is one of the three main tunnels which channeled the water from behind the Gargar Bridge-Dam into the water mill and then run several water mills. Seh koreh canal channels the water from behind the GarGar bridge into the western side. In the water mills and water falls, we can see a perfect model of haltering to run mills. The Band-e Kaisar ("Caesar's dam"), an approximately 500-metre (1,600 ft) long Roman weir across the Karun, was the key structure of the complex which, along with the Mizan Dam (Band-e Mizan), retained and diverted river water into the irrigation canals in the area. Built by a Roman workforce in the 3rd century AD on Sassanid order, it was the most eastern Roman bridge and Roman dam and the first structure in Iran to combine a bridge with a dam. Parts of the irrigation system are said to originally date to the time of Darius the Great, an Achaemenian king of Iran. It partly consists of a pair of primary diversion canals in the Karun river, one of which is still in use today. It delivers water to the Shushtar city via a route of supplying tunnels. The area includes Salasel Castle, which is the axis for operation of the hydraulic system. It also consists of a tower for water level measurement, along with bridges, dams, mills, and basins.
