10.Shushtar Historical Hydraulic System (2009)
The Shushtar Historical Hydraulic System demonstrates outstanding universal value as in its present form; it dates from the 3rd century CE, probably on older bases from the 5th century BCE. It is complete, with numerous functions, and large-scale, making it exceptional. The Shushtar system is a homogeneous hydraulic system, designed globally and completed in the 3rd century CE. 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 Shushtar Historical Hydraulic System testifies to the heritage and the synthesis of earlier Elamite and Mesopotamian knowhow; it was probably influenced by the Petra dam and tunnel and by Roman civil engineering. The Shushtar hydraulic system, in its ensemble and most particularly the Shadorvan Grand Weir (bridge-dam), has been considered a Wonder of the World not only by the Persians but also by the Arab-Muslims at the peak of their civilization. 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. The Shushtar Historical Hydraulic System sits in an urban and rural landscape specific to the expression of its value.
Justification for Inscription
Criterion (i): 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.
Criterion (ii):The shushtar Historical Hydraulic System is a synthesis ht together to form a remarkably complete benefited from the ancient expertise of anal irrigation, and then that of the fluenced its construction. Its many
Criterion (iii): The Shushtar of diverse techniques broug and large-scale ensemble. It ha the Elamites and Mesopotamians in c. Nabateans; Roman technicians also in visitors marveled 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.
Criterion (vi): 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, defense 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.
