Sumario:Despite the advancement of technical tools for the analysis of complex systems, the most important issue in solving water resource problems focuses on the interaction of human and natural systems. Agent-Based Model (ABM) has been used as an effective tool for the development of integrated human and environmental models. One of the main challenges of this method is identifying and describing the main agents. In this study, three main approaches including Genetic Algorithm (GA), cooperative game theory and ABM have been used to optimize water allocation in Tajan catchment. The proposed ABM is a new equation for calculating stakeholder utility and simulating their interactions that can create a hydrological-environmental-human relationship for demand management and optimal water allocation. The results showed that the total benefit of cooperative game theory and ABM relative to GA has been increased 24% and 21% respectively. Although the total benefit in game theory is greater than the ABM, but the ABM considering the agents feedback propose a more comprehensive approach to optimal water allocation. HIGHLIGHTS Combining of GA optimization model with ABM.; The total benefit of game theory and ABM is significantly more than the GA.; Proposing an Agent-Based Equation to solve water conflicts and finding solutions based on social and hydrological interactions.; Comparing the results of game theory and the proposed ABM and GA in water allocation to stakeholders.;
