The average diameter of sediment flux to the sea is found to be negatively correlated with the annual shift of the thalweg of the lower Yellow River .

入海泥沙平均粒径与 深泓年 摆 幅之间也存在着负相关关系。

The effects of permeable pile groynes laid out along the thalweg in control and guide the regime of the lower Yellow River have been studied through movable bed model tests .

通过河工动床模型试验，对沿治导线布设形式的透水桩坝在黄河下游控导 河势的效果进行了研究。

The study shows that the technology and method of distilling the thalweg using DEM are practical and effective .

实验结果证明，利用DEM自动提取 沟 沿线是一种 快速、有效的技术方法。

The thalweg in loess hill area is an important terrain structural line reflecting topography and landform character .

黄土丘陵区的 沟 沿线，是反映该区地形地貌特征的重要的地形结构线。

Siltation features downstream of a barrage built at the mouth of a tributary is mainly conditional on the alignment of the thalweg of the main river and is essentially different from that in the main river estuary .

在潮汐河口支流口门上建闸，其闸下淤积面貌主要取决于 干流 主槽 的 位置，这与在潮汐河口干流上 建 闸 的 闸下淤积问题有着本质上的差异。
