Dam construction and development projectshave serious effects on environmental parameters. Therefore, environmental risk assessment of the dam is one of the most important aspects of environmental risk management in these projects. The purpose of this study is to provide a new model for assessing the environmental risks of dams during the construction phase. To this end, after identifying environmental risks and using the EFMEA method, the RPN for each environmental aspect was calculated and classified. The VIKOR method was used to assess and prioritize identified environmental risks. The results show that in the EFMEA method and by comparing the calculated risks, the risk of pollution of the Balarood river with, RPN 125 is the first priority. In the VIKOR method, the risk of water pollution (high, medium, low) with weight (1,300, 1,000 and 0,700) was identified as the most important risk. In this paper, EFMEA and VIKOR methods are used to assess the environmental risk of the dam. The most important modified action to reduce environmental risks is the construction and completion of wastewater treatment plants for industrial units.
