History

As in its present form, it dates from the 3rd century CE, probably on older bases from the 5th century BC. The dam was built by Roman soldiers and engineers who were taken into captivity along with Valerian (emperor) (reign 253–260 CE) after his defeat by Shapur I (241-272 CE).[2]<ref name="Tehran Times 45004"> [4]

Function

Mizan Dam is located upstream of a manmade canal called Gargar which was dug in order to divert water from the Karun River. The dam regulates water for Gargar (a tributary stream branched from Karun) and this way, Mizan is considered a regulatory dam [2] [3]

Material

The elemental materials of this site are stone, Saruj mortar and sandstone in foundation that all of them have maintained their authenticity, and there aren't any interventions. But there are differences in some part of site due to different restoration periods.[2]

Threats

Due to the location and nature of Mizan Dam, this dam is sometimes submerged. Several flooding has occurred during previous decades which affected the dam.[2]
