State-of-the-art review of reservoir adaptation operation in changing environment

In the changing environment driven by climate change and human activities, traditional reservoir operating rules, designed based on stationary hydrological condition, cannot perform well as reservoir managers requested. This forces reservoir managers to make adaptive adjustments to ensure safety and efficient utilization of water resources. Therefore, reservoir adaptation operation in changing environment is a frontier and hot topic in the field of reservoir operation at home and abroad. Many international experts and scholars have carried out plenty of excellent works. This study is aimed to provide the state-of-the-art review of reservoir adaptation operation in recent decades. It includes three crucial parts:(1) reservoir inflow projection method in changing environment, (2) derivation method of reservoir operating rules, and (3) the methodological framework incorporating changing environment-reservoir inflow-reservoir operating rules. The main research problems are also summarized in this paper. Furthermore, future potential directions of reservoir adaptation operation are discussed, such as how to project reservoir inflow considering natural and artificial dual effects, and how to achieve static connection and dynamic adjustment of reservoir operation strategies. © 2022 China Water Power Press.
