The simulation of reservoirs is a low-cost way to analyze the efficiency of them storing water, a very important matter for the endurance of the inhabitants of the Brazilian semiarid in dry periods. Therefore, it was developed in the Federal University of Ceará (UFC), in the late 1990’s, the software SimRes, which uses the Monte Carlo Method, the Fragment Method of Svanidze, and the Triangular Diagram Method of Campos to generate synthetic inflow series and simulate the behavior of the reservoirs exposed to them. In the year 2000 in the UFC, the main reservoirs of the Jaguaribe Basin were simulated with the aid of SimRes. It was found that, even with more than 80% of control over its basin, 35% of the Jaguaribe River’s natural discharges keep on flowing to the ocean. Due to the importance of the Jaguaribe Basin, from which more than half of the population of Ceará State gets tis water, this study to verify the validity of this information, by simulating the twelve largest reservoirs of the Jaguaribe Basin through the software SimRes. The inflow data used in the simulation were obtained from three fluviometric stations, and regionalized to each reservoir analyzed, the process was then repeated with a hypothetical coefficient of variation of 0,2 (similar to the ones of the perennial rivers of Northeast United States), to verify the effect of it in the results. The value of annual inflow that is spilled from the reservoirs and reaches the ocean found in this study is very similar to the value found in the previous one. Also, it was demonstrated that, in the hypothetical situation of a lower coefficient of variation, the volume of water spilled from the reservoirs is reduced in 93%.
