| 摘 要： | 面积、平均水深相同的断面,形态不同,输水、输沙能力有较大差异。导得了断面特征值,包括表称流量、表称输沙率、表称含沙量、宽深比等的计算式。讨论了断面形态的变化及其表达方法。提出了几种平均水深的算法。讨论了常用的√B/H关系,认为用它来表达断面形态、判断变化性质是不合理的。

| Abstract: | Computing expression for the characteristic parameters of a river crosssection including flow Q,silt discharge Q5,silt concentration S and depth (H) width (B) ratio Hb is developed in the paper.The variation of cross-section and its expression are also discussed.The paper indicats that the usual relation,√B/H widely used needs to be further improved in expressing the variation of cross-section morphology. |
