Research Abstract

A prior assessment of bed deformation due to rive or coastal development provides helpful information to discuss environmental hydraulics. Investigation of inner structure of a dense particulate flow by using a sophisticated numerical tool is fully expected to contribute to scientific knowledge about be deformation. Thus, in the present study, large eddy simulation for particulate flow has been performed, and inner structure of particulate flow has been addressed from the viewpoint of computational sediment transport dynamics.
