Özet
Environmental flow is defined as the flow that is necessary to protect and maintain ecosystems and determination of the quantity of environmental flow is important for the management of multi-objective water resources systems with multiple dams. In this study, an optimization model, taken into account different working times of hydropower plants (12, 15 and 18 hours a day), is developed to determine the releases from dams for electricity production and environmental flow. The developed model consists of an objective function that maximizes the releases from dams for electricity production and environ-mental flow and satisfies all operational conditions such as range of water releases, range of dam storages, irrigation releases and also mass conservation between inflows and outflows. A water resources system in the Aksu River Basin including Karacaören I and II Dams located in the Mediterranean Region, Turkey is selected for application and the model is applied for the year 2010. MINOS, a sol-ver employing the Lagrangian algorithm and the reduced gradient method in General Algebraic Modeling System (GAMS) program, is used for solving the optimization problem. It is determined that the ratio of total electricity production to total firm energy ranges between 77.7% and 90.5% while the ratio of total environmental flow quantity to annual natural flow quantity ranges between 56.1% and 48.9%. These results show that the developed model can be useful for the management of multi-objective water resources systems with multiple dams in series.
