Sikaha waterfall

In ancient times Shushtar was famous for its dams and irrigation systems. Three of the dams date back to Sassanid times (3rd to 7th century CE), of which the largest was 550 meters long. The dam system fell apart through the 19th century. But even today, several waterwheels help run flour mills and produce electricity. It was at Shushtar that Shapour I, after his great victory (A.D. 260) over Valerian at Édhessa, set his captives to work building vast hydraulic works, including a large dam across the Karun River. The historical Shushtar waterfalls are among the few ancient water structures in Iran used since the time of the Achaemenid for irrigating the Shushtar plain.
