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。
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.
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.
