CAUSES OF BACK-SILTATION IN THE NORTH PASSAGE OF YANGTZE ESTUARY AND EVALUATION OF THE ENGINEERING MEASURES

[摘要] This study focused on the fact that the amount of back-siltation in the deep waterway of North Passage has been increased and converged in the middle reach since 2005.This paper systematically analyzed impacts resulting from the change of various factors such as sediment and hydrodynamics conditions, pointed out the major reason resulting in the increase on the amount of back-siltation in the middle reach, and discussed engineering measurements to reduce the siltation. The engineering effects of the measures were evaluated after the constructions as well.
