Reservoir operations is a field of study that focuses on the management and optimization of water storage in reservoirs to meet various objectives such as flood control, water supply, hydropower generation, and environmental protection. This research area involves the development of mathematical models, algorithms, and decision-making tools to efficiently operate reservoir systems under changing hydrological conditions. Researchers in this field aim to maximize the benefits derived from reservoir storage while minimizing negative impacts such as water shortages, environmental degradation, and conflicts among different water users. They also study the impacts of climate change on reservoir operations and develop strategies to adapt to changing hydrological patterns. Overall, reservoir operations research plays a crucial role in ensuring the sustainable and efficient use of water resources in a rapidly changing world.
