摘要
利用废黄河口夏季和冬季实测水文泥沙资料,对多个典型的悬移质挟沙力公式进行应用计算,在此基础上,采用相关系数法、标准化最小距离法、集中系数法、偏离系数法4种检验方法对计算结果进行比较分析。结果表明:河口水流挟沙力公式能够较好地反映废黄河口水域的水流挟沙情况,并且具有较高的精度;对于各种检验方法,因为侧重点不同,所得到的检验结果会产生矛盾,所以建议采取多种检验方法对挟沙力公式进行综合评价。
Using the hydrologic and sediment data measured in summer and winter of the Yellow River delta,multiple formulas had been used to calculate the sediment-carrying capacity. On this basis,comparative analysis of correlation coefficient method,standardized mini-mum distance method,concentration coefficient method and deviation coefficient method were used. The results show that the estuarine sedi-ment-carrying capacity formula can reflect the sediment transport condition of the ancient Yellow River delta and has high accuracy. Due to each test method with different focus,contradictory test results will be obtained,so we need using multiple test methods in this study.
