The purpose of this study was to evaluate the environmental risks of Alborz Dam on Babolrood River in Babol city, using MCDM methods. First, the environment of the study area was identified, then a list of identified environmental risks was prepared in the construction and exploitation phase, and in the form of a questionnaire was provided to environmental experts familiar with the Alborz dam basin. Environmental risks were rated by experts according to the Likert scoring range based on the three indicators of occurrence intensity, probability of occurrence and risk significance, then environmental risks ranking was performed using OWA method. The most important risks of Alborz dam were obtained during the construction phase: when the decision maker is risk aversion, respectively: Destruction of forest within the dam with a score of 0.048, Displacement of reservoir residents with a score of 0.047, and, When the decision maker is risky, respectively: Destruction of forest within the dam with a score of 0.051, Displacement of reservoir residents with a score of 0.050. Also, The most important risks of Alborz Dam were obtained during the operation phase: When the decision maker is risk averse, respectively: Thermal stratification of dam reservoir with a score of 0.053, Reduction of self-purification of Babelrood River with a score of 0.051, and, When the decision maker is risky, respectively: Thermal stratification of dam reservoir with a score of 0.057, Landslide with a score of 0.056.
