Abstract :

Dams can produce electricity and ensure water security, but at the same time they radically alter the hydrological regime of rivers with significant consequences for the economic and environmental welfare of the region in which they are located. consequences of constructing dams in most parts of the world have become controversial. The aim of this research is to explore the consequences of heightening Ekbatan dam wall on Living conditions of the villagers living downstream of the dam social and economic condition. The consequences of constructing this dam are more remarkable in downstream area in terms of geographical situation. The research data were obtained using a field survey and through a questionnaire completed by 150 inhabitants in the downstream villages. To investigate the economic and social consequences of heightening dam wall on the living conditions of the villagers living downstream, Bayesian structural equations were used and a model was presented. Based on the research results, social indication (Bayesian coefficient =0.919)had the greatest affected living conditions of the villagers living downstream of the dam
