Tehran Times – A water transfer system has been established to transfer water from Karun river to Shadegan wetland in order to revive the international wetland, Mehr news agency reported on Tuesday.

The wetland feed on Marun and Karun rivers both crossing Kohgiluyeh and Boyer-Ahamd province, but after dam construction over the Karun river the wetland went dry not receiving its water right.
