黄河调水调沙:洪水控制、洪水利用与洪水塑造的协同实践OA

The Yellow River is characterized by scarce water and abundant sediment,with an uncoordinated water-sediment relationship,which has long been a major public concern.Water and sediment regulation is the primary technical measure to regulate the water-sediment relationship of the Yellow River.Through the joint operation of reservoir groups such as Sanmenxia and Xiaolangdi,artificial flood processes have been successfully shaped,effectively achieving the goals of flood control and disaster mitigation in the Yellow River basin,downstream channel scouring,and estuarine ecological management.In 2025,three rounds of water and sediment regulation were conducted on the Yellow River:one pre-flood regulation and two during the flood season.Based on the data from these operations,this paper provides an in-depth analysis of how water and sediment regulation in the Yellow River reflects the principles of flood control,flood utilization,and flood tailoring.The three operations achieved the set goals of reservoir sediment flushing and downstream channel scouring,while mitigating impacts on aquatic organisms and their habitats.The successful practice of water and sediment regulation verifies the feasibility of a modern integrated river management model based on the logical framework of"flood control,flood utilization,and flood tailoring".By regulating water and sediment through reservoir groups,flood risks are transformed into manageable resources and ecological drivers,achieving the goals of"no riverbed aggradation,no dyke breaches,no flow cutoff,and no ecological degradation"for the Yellow River.This practice also provides a valuable reference for the sustainable management of sediment-laden rivers.
