The prediction of the effect of ocean engineering on Jintang tidal channel evolution

摘要

Tidal channel is the most important waterway of harbor in coastal area, Jintang tidal channel is a natural tidal passage and waterway of Ningbor Port in the south-east side of Hangzhou Bay,. It is an important passage for tide passing in and out in Hangzhou Bay too. There has been a continuous shoals reclamation in the west side of it because of the demand for land and other ocean engineering such as port and bridge recently, this is potential threaten to the channel. With investigation, shore evolution, dynamic analysis, numerical simulation and model prediction, This paper gives a research for the evolution of Jintang channel, the variation of dynamic induced by different reclamation and ocean engineering, and builds a prediction model using equilibrium theory of dynamic and water depth adaption in channel, it shows that the runoff will be reduced and the sea bed will be adjusted suitably after reclamation and related adjacent human activities around the channel.
