| 英文摘要 | Reservoir operations alter natural flow regimes by redistributing water spatially and temporally. Understanding and addressing the resulting impacts on natural flow regimes are crucial for effective river management to maintain the health and resilience of riverine ecosystems. This study contributes a comprehensive assessment regarding the impact of reservoir operations on flow regimes across the Contiguous United States (CONUS). We first identified admissible flow variation range based on reservoirs' inflows and calculated the High and Low Flow Impacts (HFIs and LFIs) of reservoir operations on flow regimes. The dynamic time warping algorithm was implemented to cluster HFIs and LFIs, enabling detailed analysis of their intra-annual characteristics. Furthermore, we conducted a comprehensive trend analysis of HFIs and LFIs from 1980 to 2020 across CONUS. Our analysis reveals notable seasonal variations in the impacts of reservoir operations on high and low flows throughout the year, with positive correlations between the annual mean HFIs and LFIs. We also identify three distinct patterns for both intra-annual LFIs and HFIs, which show minimal correlation with geographical location or the primary purposes of reservoir use. The trends of the annual HFIs and LFIs highlight diverse patterns, indicating substantial reductions in HFIs and simultaneous increases in LFIs in numerous reservoirs over recent decades. These trends are not associated with reservoir capacities, discharge levels, or the degree of regulation but are correlated with trends in annual mean flows. Our results highlight the complex, evolving nature of flow regime alterations and emphasize the need for adaptive management strategies that account for both seasonal variations and long-term trends in reservoir operations. These findings provide critical insights for developing sustainable river management practices that balance human water needs with ecosystem conservation requirements. |
