Abstract

Abstract

Environmental flow (e-flow) management is very important for protecting downstream riverine ecosystem. In the research of reservoir ecological operation, in order to provide different e-flows for different periods, the e-flow management becomes more and more complicated. People tend to adopt more complicated e-flow management to improve ecological flow regime. However, not only e-flow management affects ecological flow regime, reservoir inflow classification also influences ecological flow regime, and further influences the results of e-flow management. Studying the effect of flow classifications on the results of e-flow management is helpful to choose the better e-flow management before reservoir operation, especially when it is necessary to consider investment cost. In this paper, through the analysis of global streamflows, three types of inflow sequences were summarized. To compare different e-flow management strategies, we adopted four universal e-flow management strategies. This paper draw some general conclusions. When reservoir inflows was distributed evenly during the whole year, the change of e-flow management strategies wouldn’t affect ecological flow regime. Thus, the reservoir inflows in this type were not sensitive to the change of e-flow management strategies.
