河流含沙量

赣州上游河流含沙量变化趋势分析

Analysis of sand content variance trend of rivers on the upstream of Ganjiang River

我国江河泥沙含量大小不一，北方河流含沙量大，尤其是西北地区含沙量很高，南方地区江河含沙量一般较小。

In China , sediment content in rivers is different . Sediment concentration is high in the north , and is much more great in the northwest especially . It is lower in the south .

与传统的各种测量河流含沙量的方法相比，此方法能够大大提高测量的精度，增强测量系统的抗干扰能力，为我国水文水资源的研究与测量提供了一种新的重要的工具。

Compared with the traditional methods of rivers ' sand content , it can improve the precision of the measure , enhance the measuring system 's resisting capacity and offer a new and important tool for the research and measure of hydrologic in our country .

但河流的含沙量增加了，河床有逐渐增高趋势。

But sediment content of the river increases , the river bed has a raising tendency .

穿过有大面积中生界和第三系地层出露地区的河流，其含沙量高，侵蚀模数大。

The rivers running across large area with emergence of mesozoic and tertiary stratum usually have high sediment concentration and large modulus of erosion .

所有单一河流断面处的含沙量通过单一河流悬沙输运的求解方法获得。

A numerical model for simulating unsteady flow and suspended sediment transport in river networks was presented .

黄河是我国第二大河流，以高含沙量闻名于世。

The Yellow River is the second river of China , with world-famous of its high sediment-laden water .
