Water is considered a major cause of international conflicts in the 21st century and one of themost controversial issues of the water sector in recent years has been the impacts of large dams.
Turkiye has made considerable progress in developing its water resources for multiple uses. Theconstruction of dams and reservoirs are the main reasons of saving water during the short rainfall
seasons to facilitate year round availability. Today, an extensive network of dams and reservoirs ismaintained of which the larger dams serve multiple purposes (e.g. flood control, irrigation,
domestic water supply, hydropower etc). Although there are many benefits arising fromhydropower, they cause negative impacts as well. Slowing down the rivers velocity causes
changes in sediment transport, storing huge amounts of water in reservoir changes significantlythe waters quality and influences the micro-climate of the area.
In this study, Yusufeli Hydropower Dam in Çoruh river project with installed capacity of540MW is analyzed for its environmental costs. For the cost analysis Yusufeli Dams height,
terrain or topography, population density and the area inundated by reservoir are taken intoconsideration. In general information chapter, the scope of the study is explained and dam
environment relationship is examined. In investigation chapter, general information of dam isgiven. Yusufeli Town and Yusufeli Dam Project are introduced and the projects characteristic
properties are given. In discovery chapter, GHG emissions cost of agricultural production lost andexpected loss of life, cost of resettlement and cost of land loss are taken into consideration.
Environmental cost of Yusufeli Dam Project is accounted.The results show that environmental cost in terms of one MWh electricity generation is about
148.97$ (221.64TL) for Yusufeli Dam. Calculated environmental cost is compared with theelectrical consumption cost and dam construction cost. Yusufeli Dams amortization period is
calculated in terms of energy production.Keywords: Yusufeli Dam, Çoruh River Development Plan, Environmental effects of dams,
