  • 摘要: 从水沙组合的角度出发,建立了基于水沙二维向量组合的频率统计方法,并在此基础上提出了有效输沙流量的计算方法。根据黄河内蒙古河段巴彦高勒站1954-2006年日水沙资料及汛后平滩流量资料,采用上述有效输沙流量计算方法计算得到了各年有效输沙流量及相应含沙量组合,进而分析了平滩流量与有效输沙流量及有效来沙系数之间的关系。结果表明,巴彦高勒站平滩流量调整分别受到包括当年在内的前期12年来水来沙条件的影响。
    Abstract: A statistical method is proposed for calculating the frequency of a two-dimensional vector combining of discharge and sediment concentration.The method can be applied to compute the effective sediment-transporting discharge a channel reach.Using the observed discharge and sediment data from the Bayangaole station located in the Inner Mongolia reach of Yellow River during the period 1954-2006, the effective sediment-transporting discharge is calculated annually.The corresponding effective incoming sediment coefficient is also obtained.The relationships between the bank-full discharge and the effective discharge, as well as the effective incoming sediment coefficient are analyzed.The result shows that the current value of bank-full discharge at the Bayangaole station in the Inner Mongolia reach of Yellow River is affected by the antecedent discharge and sediment conditions in the previous 12 years.
