About Shushtar Hydraulic System
Sassanid re-engineering of the Karun River where the Band-e Kaisar (Caesar's Dam) — said built by Roman soldiers captured with Emperor Valerian — diverted the river into the Gargar canal feeding 40 watermills, weirs and reservoirs. The complex includes the Salasel Castle regulating dam, Dahaneye Shahr bridge-dam and extraordinary manual tunnel of Abshaar. Still partly functional, it embodies Sassanian 'master of waters' ideology.
