The Shushtar Hydraulic System is testimony to a remarkably accomplished and early overall vision of the possibilities afforded by diversion canals and large weir-dams for land development. It was designed and completed in the 3rd century CE for sustainable operation and is still in use today. It is a unique and exceptional ensemble in terms of its technical diversity and its completeness that testifies to human creative genius.
The Shushtar Historical Hydraulic System is a synthesis of diverse techniques brought together to form a remarkably complete and large-scale ensemble. 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. Its many visitors marvelled at it and were in turn inspired. It testifies to the exchange of considerable influences in hydraulic engineering and its application throughout antiquity and the Islamic period under the various Iranian dynasties.
Shushtar is a unique and exceptionally complete example of hydraulic techniques developed during ancient times to aid the occupation of semi-desert lands. 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. It testifies to a technical culture dating back eighteen centuries serving the sustainable development of a human society, in harmony with its natural and urban environment. The Shushtar Hydraulic Systemwas inscribed on the national heritage list of Iran in 2009.
