Investigating Some Consequences of Farrokhi Dam Construction in Qaen City

Dams leave various environmental effects on local communities and watersheds, during the stages of construction, operation and end of useful life. The current research was carried out to evaluate the environmental effects of the Farrokhi Dam in the operation phase on the physical, cultural, economic and social environments. In this research, the modified Leopold matrix and the modified rapid impact assessment matrix were used. Positive and negative effects were studied and valued. The stability of the Phillips method was evaluated and its results were compared with the modified Leopold matrix and the modified rapid impact assessment matrix. The results of the rapid impsct assesment  method showed that evaporation with a coefficient of -14.25 has the most negative effect. Besides, regardless of secondary consequences, agricultural development is the most positive effect of dam construction with a factor of 105. Based on the results, the Phillips stability factor for Farrokhi Dam was equal to 2.87. Therefore, despite the presence of some positive effects, it was found that the cultural effects of Farrokhi dam construction were completely negative and the most negative effect of Farrokhi dam is in the field of evaporation.
