ABSTRACT

ABSTRACT:   Taking Dandong Port as the representative of dig-in basin in strong tidal estuary, the author intends to make a research on the water and sediment characteristics of dig-in basin. By means of numerical simulation method, the study suggests that the hydrodynamic and sediment concentration decrease gradually from the harbor entrance to terminus in Donggou 1# basin. The differences of hydrodynamic and sediment concentration in harbor entrance are larger than that of harbor terminus. The harbor sedimentation intensity of spring tide is higher than that of neap tide, and the harbor sedimentation intensity in harbor entrance is higher than that of harbor terminus.
