Channel Evolution of Chengtong Reach at Yangtze Estuary

摘要

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