Need to Reduce Water Evaporation in Iran Dams

A whopping 3 billion cubic meters of water evaporates annually from dams nationwide, head of water technology development workgroup at the Presidential Office for Science and Technology said.
“As the water crisis worsens, developing efficient water management techniques to preserve finite resources (like aquifers) should become a priority,” Jahangir Porhemmat was quoted as saying by ISNA.
Amir Kabir Dam, one of the biggest in Tehran, can hold maximum 200 million cubic meters of water, and the amount of water wasted in dams (3 bcm/year) due to exposure to direct sunlight is 15 times the size of this structure, he said.
