| 摘 要： | 天然多沙河道水面线的升降与河道平面形态、过水断面形状、河床粗糙度及河床植被、河床的扩展及收缩、河床组成及其冲淤变化等众多因素有关。以南水北调中线总干渠交叉河道水面线推算为例,分析了天然多沙河道水面线推算中尚需注意的几个技术问题,提出了解决问题的思路和具体的处理方法,具有示范作用,对类似河流的洪水水面线推算有一定的借鉴意义。 |
| 关 键 词： | 南水北调 天然河道 水面线 糙率 水头损失 |

| Abstract: | The change of natural sandy river water surface is in relation with river planar shape, cross shape, roughness and vegetation, river bed expansion or contraction, river bed composition, scour and silting. Taking calculation of the cross section water surface curve of the general channel of the south-to-north water diversion, several problems which need to be noticed and resolved in natural sandy river water surface calculation were analyzed. The detailed processing method and way of solving problems were put forward. |
| Keywords: | south-to-north water diversion project natural river water surface curve roughness head loss |
