INTRODUCTION Many dams have been recently constructed in Iran with different purposes, from storing water for agriculture and industrial usages, to household uses for hundreds of years in Persian culture historically. Hydroelectric dams, additionally, act as an alternative to non-renewable energy resources that constitute the majority of the world’s energy [1]. Despite enormous benefits of dams, they may have drastic damaging effects on the environment and on the populations that live near dams and thus, have become the subject of great scrutiny, with organizations concerned with environmental health such as Iranian Environmental Organization [2]. In a worldwide perspective, Out of the 38,000 large-scale dams, registered by the International Commission on Large Dams (ICOLD), an international organization that sets the standards for dams, 50 percent of dams are used for irrigation, 18 percent for hydropower, 12 percent for water supply and 10 percent for flood control and the rest for other functions [3]. As such, external effects such as environmental issues are of a huge consideration for any nation. 556
