Reservoir operation is one of the most important issues in the management of water resources, due to the increasing demands for water compared to the increasingly limited water resources available. Efficient water resources management is achieved through the establishment of optimal operation policies and reservoir operation rules. The latter include decisions on the deliveries to be provided by the reservoir and the volumes to be impounded in each period of time. Based on the need for an efficient and rational use of water, mathematical modeling has been used as a tool to obtain solutions for the optimal operation of existing reservoirs. In the present work, a study is carried out to obtain an optimal operation policy for a water supply system of reservoirs with several interconnected users in the city of Santiago de Cuba. The study consisted of proposing a water delivery plan from the reservoirs to the users to obtain an optimal distribution of water in the reservoir-user system. In order to achieve this objective, the WEAP mathematical simulation model has been applied to the Northwest Water Supply System to the City of Santiago de Cuba, chosen as a case study. As a practical result of the application of the WEAP model, it is possible to obtain a water delivery plan that guarantees 90% of the water to the users. The results obtained with the WEAP model were compared with the results obtained with the HEC-PRM model for the same case study, showing that both models provide similar results.
