However, conflicts can arise over its use when there is a water imbalance, that is, when the supply of water is less than the demand. To minimize this problem, the construction of reservoirs to meet the demands is a recurrent solution in semi-arid regions, which are characterized by having great hydrological variability, both spatial and temporal. For a good management and maximization of the use of reservoirs, operating rules can be applied, in order to optimize user service. To solve the optimization models, computational intelligence techniques are used to solve complex problems, among which the genetic algorithm is an important tool in solving problems related to the management of water resources. Thus, the objective of this work was to evaluate the performance gain in meeting the demands of water with the definition of operation rules in the reservoirs, operating in an isolated and integrated way, using the genetic algorithm in the optimization through the simulation of the water balance of the reservoir. The evaluation was obtained through performance indicators reliability, efficiency (volumetric reliability), resilience, vulnerability and main water outputs from the reservoir (demand supply, spillage and evaporation). The study area is located in the Brazilian semi-arid region, in the Piancó-Piranhas-Açu river basin, specifically in the Dourado and Marechal Dutra reservoirs. The results showed that water infrastructures contribute to meeting the demands, as they reduce failure periods. In addition, rationing rules can provide an increase in efficiency in the integrated operation in meeting priority demands. Also, a great loss of water volume by spillage or evaporation was observed, therefore, it is desirable that future studies can incorporate in the optimization different rationing coefficients for dry and humid periods in the definition of the operation rules.Acesso AbertoOperação de reservatóriosGestãoOtimizaçãoAlgoritmo genéticoRegras de operaçãomasterThesisCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA
