【摘要】

采用实测资料分析和数学模型计算等多种手段分析了支流来水来沙对宁蒙河段淤积的影响。结果表明:宁蒙河段支流来沙量与干流淤积量的相关性较强,是影响宁蒙河段淤积的主要因素之一;考虑支流来水来沙与不考虑支流来水来沙相比,宁蒙河段年均多淤积0.301亿t,1986年以前年均多淤积0.207亿t,1986年以后年均多淤积0.377亿t

【英文摘要】

In this paper,the effect of tributaries to the scour and fill of Ning-Mong Reach of the Yellow River was studied by observed data analysis and numerical simulation.The results show that,the effect of tributaries is one of the key factors which affect the scour and fill of Ning-Mong Reach,because there is a strong correlation between the sediment of tributaries and bed sedimentation in Ning-Mong Reach.The sediment deposition caused by tributaries is only 0.301×108 t annually with the selected conditions,befo...
