   One of the serious challenges in inter-basin water transfer plans is the existence of various complex which, due to their different roles and effectiveness in implementation, have caused many problems in the environmental, economical, cultural, social, technical fields.Therefore, the aim of this study was to identify and prioritize effective consequences in inter basin water transfer plans using the opinions of 41 experts and specialize expert faculty members in this field. In this regard, a researcher-made questionnaire was used to identify the effective and important consequences of inter-basin water transfer plans from three environmental, economic and social perspectives and the entropy technique was used to calculate their weight. In the following, the preferential technique based on similarity with the ideal solution (TOPSIS) was used to prioritize of effective consequences. The analysis of the findings of this study by completing the questionnaire identified 29 consequences (indicator) from environmental, economic, social aspects for inter-basin water transmission projects, including 9 ecological consequence, 7 economic consequence and 13 social consequence for evaluating inter basin water transfer plans. The results of weighing the consequences using the Entropy technique showed that the sociol consequence with weight (0.44744), environmental consequence with weight (0.31102) and economic consequence with weight (0.24153) among the consequences. From the environmental point of view of the destruction of swamp and wetland life downstream of the orgine watersheds consequence with weight (0.034655), economically point of view of heavy structural cost (pumping station, tunneling and piping, desalination, etc.) with weight (0.03462) consequences and socially the consequence of protests, disputes, social, ethnic conflicts, and discrimination in a society with weight (0.03465) have the highest weight among other consequences respectively. The overall results of this study indicated that the positive and negative consequences of inter-basin water transfer schemes must be considered by the water-related organization to monitor and maintain the sustainability of natural ecosystems and achieve sustainable development goals.
