| 摘 要： | 断面法和输沙率法是计算河道冲淤变化量广泛采用的两种方法。本文根据断面法与输沙率法的特点,简单介绍了两种方法的计算模式,对比分析了断面法与输沙率法计算河道冲淤量的优缺点,并对两种方法产生的误差进行了分类,之后总结了国内外专家学者对两种计算方法优化研究发展的现状,最后就断面法与输沙率法计算河道冲淤研究的几个亟待深入的课题略谈管见。

| Abstract: | The cross-section and sediment discharge methods are the two methods to quantitatively calculate the river sedimentation.Based on their respective characteristics,the authors firstly introduce the computational models and analyze the advantages and disadvantages and the reasons to cause error of the two methods.The development status of the two methods by the domestic researchers is then summarized.Finally,the further study to improve the calculation method for river sedimentation is discussed. |
