摘要
Abstract
The meandering river channel will be generally eroded during the beginning operation stage of Xiaolangdi reservoir because it changes the conditions of inflow as well as sediment into the lower Yellow River. Although cutting down of the river channel can bring about advantages to stable river channel, it will not eliminate the threaten from transverse flow, oblique flow and so on. The results of model experiment of digging out sedimentation and solidification of dykes in meandering river conducted by the Institute of Hydraulic Research of YRCC demonstrate that the purpose of regulating river regime can be reached in meandering river through digging out sedimentation as long as it is feasible and practical. The period of Xiaolangdi reservoir discharging clear water causing local scouring will provide the advantageous conditions in the meandering river for regulating the river regime through digging out sedimentation. Therefore, it will promote solidification of the meandering river reaches through digging out sedimentation to dredge the channel in some reaches, and combining channel harness with sedimentation clearance treatments during the initial stage of Xiaolangdi operation.关键词
