tidal current limit

But this process is non-linear, which means when the river discharge or the tidal range is smaller, the influence of their change to the tidal limit and tidal current limit is greater.

潮区界和潮流界随径流量和潮差的变化并不是线性的，径流量越小，潮差越小，它们的变化对潮区界和潮流界的影响越显著。

The established numerical model is used to simulate the impact on the hydrodynamic environment in this reach, especially that on the locations of the tidal limit and the tidal current limit.

利用建立的数学模型模拟沿江抽、引水对该河段的水动力环境的影响，尤其是对潮区界和潮流界的位置变动的影响程度。

The Tong Cheng Reach is the lower part of the Yangtze River, where the water abstraction is active and gives impact both on the location of the tidal limit and on that of the tidal current limit.

通澄河段是长江下游感潮河段，沿江抽、引水频繁，对潮区界和潮流界都有影响。

Based on the study of ideal estuary, this article has studied the tidal limit and tidal current limit of Yangtze estuary by using the 2-D numerical model.

第二部分在理想河口研究的基础上，对长江下游感潮河段进行了水动力数值模拟。

Research on the Location of Tidal Current Limit of Yangtze River

长江潮流界位置探讨

Internationally, it has been an irresistible tidal current to prohibit the arrestment at will and not to limit citizen's personal freedom after the undue legal process.

在国际上，禁止随意逮捕、非经正当的法律程序不得限制公民的人身自由已经成为一种势不可挡的潮流。

South-to-North Water Diversion Project will make neap tidal current limit move upstream about 10km, but affects spring tidal current limit little.

南水北调对对潮流界的影响比对潮区界的影响大，1月调水1000m~3／s时使小潮潮流界上移10km，对大潮潮流界无太大影响。

Study of tidal limit and tidal current limit is one of the important components of global Land-Ocean interaction. Systematic study of them is of significant meaning both in practice and theory.

感潮河段潮区界、潮流界的变化是全球海岸带陆海相互作用研究的重要内容，对它进行系统研究具有重要的理论和实践意义。

The distributions of water level, velocity and discharge along this reach are calculated according to different amount of the water abstraction and their impacts on the locations of the tidal limit and the tidal current limit are analyzed.

通澄长河段抽引水影响研究根据计算结果对比分析了不同抽、引水量下的水位、流速以及流量的沿程分布，及对潮区界、潮流界和下泄流量的影响。
