The limitations and accessibility of water resources juxtaposed against the increasing demands for water resources due to a combination of growing populations and the scarcity of water for their needs in many regions around the world, specifically in countries located in arid and semiarid regions. One method to remedy the issue is a transfer of water between basins, which is a huge undertaking as it can involve diverting water from surpluses (such as a river) to the regions with limited access to water. However, due to technological, financial, socio-economic, and environmental constraints, projects of this nature require that several criteria be considering before undertaking a project to transfer water [3]. Iran, which has both arid and semi-arid regions within its borders, faces water shortages in large swaths of the country, particularly the central and southeastern regions. In this research paper, a hierarchical decision model (HDM) was implemented in order to rank four water transfer options to the Zayanderud basin in central Iran. The approach outlined in this study takes the four most reasonable options for transferring water to the basin and outlines major and subcriteria that were determined by an extensive review of literature and opinions provided by experts on the transfer of water. From here, the HDM is further refined by using the ETM-HDM online software provided. This model allows for a comparison of tangible factors with varying priorities by way of a pairwise comparison. The hierarchy consisted of four levels: goal, criteria, sub-criteria, and alternatives. A group of 7 experts with various backgrounds and more than 15 years of experience in water and environmental issues were invited from companies, governments, and academia. Accordingly their judgments were quantified and incorporated into the online model.
