Channel Evolution of Chengtong Reach at Yangtze Estuary

摘要

This study combines the field data analysis and the numerical simulation to analyze the channel evolution of Chengtong reach, which is located at the upper section of the Yangtze estuary. It is found that the main dynamic factor to shape the estuary channel is the ebb current. The recent changes of averaged ebb current velocity in the main channel show that the Chengtong reach is still in the process of development.
