tidal limit

基本解释

Because the pipeline diameter in platform is one third of that in tidal channel, so the limit scour length is less.
而平台区由于设计管径仅为潮汐通道区的三分之一，其极限冲刷长度远小于潮汐通道区。
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。

潮区界
South-to-North Water Diversion Project have little effect to tidal limit.
南水北调对对潮区界的影响甚微，可以忽略。
