黄河下游河道输沙水量及计算方法研究

Research on water volume of sediment transport and the calculating method in the lower Yellow River

  • 摘要: 根据黄河下游1950年以来的水沙、河道冲淤及洪水观测资料,系统分析了黄河下游主要控制站输沙水量与来沙量、洪水量级、水沙搭配、区间引水引沙及河道允许淤积度等因子间的相互关系。在探讨泥沙输移规律和机理的基础上,引入水沙搭配参数,建立了适用于黄河下游主要控制站汛期及洪水期计算输沙水量的数学表达式,量化了水沙条件及河道允许淤积度变化对河道输沙水量的影响程度。该研究对维持黄河健康生命及黄河水资源的规划利用具有重要的理论和实际意义。

     

    Abstract: According to the observed data of water and sediment,deposition and erosion,flood information,etc since 1950,the interrelationship among water volume of the sediment transport,the oncoming water and sediment,the flood discharges,the index of sediment and flow matching,the water and sediment diversion,the permissible deposition in the river course,etc,are studied in this paper.Based on the sediment transporting law and the index a formula which can be used to compute the water volume of the sediment transport in flood period and flood season at the controlling stations of the Lower Yellow River is set up.The formula expresses quantitatively the impact of water and sediment changing,and permissible deposition to the water volume of the sediment transport This research is very important for the plan and utilization of water resource and is very significant for keeping the Yellow River health.
