human-resource related to water systems are known as complex systems. Cellular automata and agent-based models are two practical tools for representing complex systems. In this research, the optimal utilization of the hypothetical reservoir with agricultural use in downstream is investigated. Artificial farmers are implemented downstream of the reservoir with agent-based modeling, and reservoir operators by cellular automation algorithms determine the optimal release over time and affect farmers. In the agent-based model, farmers are unique, intelligent, with historical memory, and different personality characteristics that rely on these differences have different perceptions of the circumstances and make different choices. Farmers in this model respond to changes in their amount of available water by changing the cropping pattern (crop type and area), applying new irrigation methods, and deficit irrigation. Cellular automata are an excellent choice in combination with agent-based models because of their high ability to meet the optimal solution for reservoir operation. In this model, interactions of agents are performed to achieve convergence in the behavior of farmers and operators. Taking into account the changes in the farmers' water requirement, make it possible to optimal reservoirs operation more adapted to reality. By employing these changes, the objective function of the reservoir operation will be decreased by about 60 percent compared to the uniform state, and the amount of water stress experienced by farmers will be reduced. By exerting dynamic demands, farmers make more profits (about 20 percent more) and make decisions that are different based on circumstances. Farmers 'risk-taking, the most crucial factor in changing farmers' behavior, is neither positive nor negative, but is like a double-edged sword and has different effects on the farmers' behaviors under various conditions. Low-risk-taking farmers by changing their crop patterns, and high-risk farmers are seeking higher profits with improved irrigation efficiency, and everyone is seeking to improve their conditions.
