摘要：A well validated two-dimensional surface numerical model for braided channel in down Yangtze River was used to analyse the effect of the channel regulation projects in Hechangzhou reach. Based on the different flow and sediment boundaries, the calculations were carried out to analyse the river bed evolution and the slit ratio under the impacts of two supposed projects. The results show that the subsequent submerged dikes nearby the existed one in left branch will be beneficial to the maintenance of the deep-water channel for right branch.
