黄河内蒙古河段冲淤演变与水沙过程的响应关系
Response relationship of erosion and deposition evolution to flow and sediment processes in the Inner Mongolia Reach of Yellow River
摘要
Abstract
Based on the analysis of measured data,the relationship between erosion and deposition evolution and flow-sediment processes in the Inner Mongolia Reach of Yellow River has been studied.The result show that the operation of Liujiaxia Reservoir in 1968 and Longyangxia Reservoir in 1986 have a significant impact on the flow and sediment processes entering the Inner Mongolia Reach,which is mainly manifested in the re-duction of incoming water and sediment,the reduction of peak discharge and the reduction of flood probability.Compared with that before 1968,the Inner Mongolia Reach has shown a reduction in deposition since 1968,and has been aggravated since 1986.The response relationship indicates that the flow and sediment process during flood season in the Inner Mongolia Reach with smaller inflow,larger coming sediment coefficient and smaller flow process parameters is not conducive to sediment transport,and the river channel is prone to sedi-mentation.On the contrary,the process of flow and sediment in flood season is conducive to sediment trans-port,and the sediment deposition is reduced or even converted to be scouring.关键词
