Complex irrigation system from the Sassanid era, island city Shushtar, Iran
Shushtar Historical Hydraulic System, (Persian: xd8xb3xd8xa7xd8xb2xd9x87xe2x80x8cxd9x87xd8xa7xdbx8c xd8xa2xd8xa8xdbx8c xd8xb4xd9x88xd8xb4xd8xaaxd8xb1xe2x80x8e) is a complex irrigation system of the island city Shushtar from the Sassanid era.
The Band-e Kaisar ("Caesar's dam"), an approximately 500-metre (1,600xc2xa0ft) 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.
Parts of the irrigation system are said to originally date to the time of Darius the Great, an Achaemenian king of Iran.
It is as rich in its diversity of civil engineering structures and its constructions as in the diversity of its uses (urban water supply, mills, irrigation, river transport, and defensive system).
The Gargar canal is a veritable artificial watercourse which made possible the construction of a new town and the irrigation of a vast plain, at the time semi-desert.
It has benefited from the ancient expertise of the Elamites and Mesopotamians in canal irrigation, and then that of the Nabateans; Roman technicians also influenced its construction.
By diverting a river flowing down the mountains, using large-scale civil engineering structures and the creation of canals, it made possible multiple uses for the water across a vast territory: urban water supply, agricultural irrigation, fish farming, mills, transport, defence system, etc.
The integrity of the hydraulic footprint is good, but its functional integrity compared with the original model is only partial and reduced, notably for the dams; it remains good for irrigation and water supply.
