One of the human activities that have a great impact on downstream ecosystems is dam construction projects. So that the construction of these projects has direct and indirect effects on the economic and social behavior of villagers and users; Knowing them and determining their strengths and weaknesses can be effective on how to implement better and more appropriate operations and projects in the future. Therefore, the aim of the present research is to investigate the human consequences of the construction of Halilroud Dam on the downstream villages. To achieve the goal of the research, a quantitative research method was used and its information was obtained through a structured questionnaire, the validity of which was confirmed by a group of subject experts and its reliability by calculating the Cronbach's alpha coefficient. The statistical population of the research was formed by local managers who included villagers and members of the Islamic councils of the villages downstream of the dam. The data was analyzed using the structural model and TOPSIS analysis as well as a set of descriptive statistics. The results of TOPSIS analysis showed that the construction of the dam had the most impact in Halilroud district and the least impact in Garmsar district. The results showed that the effects of the construction of Halilroud dam decreased with increasing geographical distance from it. Also, the results showed that despite its positive social effects in the villages near the dam, it has caused the most important negative social effect, i.e. displacement of people and as a result the loss of houses, fields, gardens and social and cultural relationships of the people in the villages near the dam. Finally, the results of Exploratory factor analysis in this research showed that the social effects of the dam were confirmed in seven key issues and the statistics and results have high reliability and reliability.
