Research on the Joint Water and Sediment Regulation Operation Mode of Guxian Reservoir and Xiaolangdi Reservoir
摘要
Abstract
In the context of continuous changes in water and sediment and engineering conditions of the Yellow River in recent times,stud-ying the joint water and sediment regulation operation mode of Guxian Reservoir and Xiaolangdi Reservoir is of great significance for water and sediment regulation in the middle and lower reaches of the Yellow River and comprehensive benefits of reservoir groups.Considering the natu-ral characteristics of large inter-annual variation of water and sediment in the Yellow River,we aimed to maximize the comprehensive utiliza-tion benefits of reservoir groups in water resources regulation.The joint water and sediment regulation operation mode of Guxian Reservoir and Xiaolangdi Reservoir was optimized,which originally focused on sediment discharge and reduction,and a"wet-year regulation and dry-year storage"operation mode was proposed.Using the measured water and sediment series since 2000,a mathematical model coupled with multi-ple modules such as sediment erosion and sedimentation,reservoir scheduling,cross year runoff regulation,and power generation was built.A comparative analysis was conducted from multiple aspects such as reservoir sediment discharge,river sedimentation reduction,water re-sources regulation and storage,and power generation.The results show that the optimized application mode has increased the sedimentation volume of Guxian Reservoir by 3 million m3 per year,the sedimentation volume of Xiaolangdi Reservoir by 2 million m3 and the downstream river erosion volume by 1 million m3.The increased regulation and storage volume of Guxian Reservoir by 2.96 billion m3,cross year regula-tion volume by 266 million m3 and power generation by 479 million kW·h.Overall,the optimized application mode can significantly improve the benefits of water resources regulation and power generation while ensuring the benefits of sediment discharge and sedimentation reduction.关键词
