摘要
根据泾河流域红河水文站发生洪水时流量与含沙量涨落变化基本相对应的特性,选用洪水过程中流量、含沙量对应点的增减变幅比例建立相关关系,对红河水文站泥沙测验方式进行研究,以期达到利用少数含沙量测次推求其变化过程的目的。结果表明,径流量与输沙量两者的变化相对独立,用输沙量与径流量相关关系法分析不可行;流量与含沙量涨水段、落水段比例系数相关性均不够理想;流量、含沙量增长率具有一定的相关性,但尚未达到使用标准。本研究对促进水文测站测报能力提升、开展水文巡测具有一定的参考价值。
According to the characteristics of the fluctuation of discharge and sediment concentration at Honghe Hydrological Station in Jinghe River basin,the increase and decrease ratio of corresponding points of discharge and sediment concentration in the flood process is selected to establish the correlation,and the sediment measurement mode of Honghe Hydrological Station is studied,so as to achieve the purpose of using a few sediment concentration measurements to calculate the change process.The results show that the changes of runoff and sediment transport are relatively independent,so it is not feasible to analyze the relationship between sediment transport and runoff.The proportional coefficient of flowsediment concentration in rising and falling water sections is not ideal.The growth rate of discharge and sediment concentration has a strong correlation,but it has not yet reached the use standard.This research has certain reference value for promoting the forecasting ability of hydrological stations and carrying out hydrological survey.
