  7. Abstract:
  8. The unavoidable consequences of increased demand for, and decreased supply of, various natural resources, especially water, have caused increased conflict over their allocation. Water allocations merely based on a water rights approach usually do not make efficient use of water for the whole river basin. Thus, there is a need for a comprehensive and stable allocation method that can satisfy all the involved interest groups. One of these methods is game theory that can be used to allocate water resources among riparian parties regarding principles of equity, efficiency and sustainability. In this study, a comprehensive linear programming model has been developed firstly to achieve the optimal allocation pattern besed on the initial water rights of the stakeholders. Then, by using the results of the water planning moled combined with the game theoretical concepts such as the Core, the Shapely Value, the Nucleolus and the Gately propensity to disrupt index, possible cases of cooperation among riparian parties have been evaluated. In this respect, not only have efficient and equitable allocations been done among different users, but also the stability of the allocations was investigated. In particular, through the case study of the Orumieh River Basin in Iran with scarce water resources and multiple users, effectiveness and potential advantages of this approach have been shown. The results of the optimization model showed that the Kordestan province has the best situation in supplying its demands relative to the other provinces and in contrast, the East Azarbayejane has the most deficiency in supplying the demands in both agriculture and environmental sectors. Moreover, by following the given allocation pattern, the amount of water entering the Lake Orumieh will be more than its environmental demad during the planning period and this point can be regarded as a promising perspective of the Lake. Besides, the analysis of the cooperative games and also evaluating the stability index revealed that the Shapely Value and the Nucleolus methods are the best ones to choose them for allocating the water resources. Thus, the results of this study showed that cooperative game theory can be applied successfully to assess the cases of cooperation in the Orumieh River Basin in conjunction with a comprehensive water planning model
