| Research Abstract |
The major conclusions obtained in the study for a coastal boundary layr are summarized as follows :
(1)In the stratified condition, internal tide with baroclinic velocity fluctuation may dominate the cross-shore exchanging motion of water mass.
(2)In the non-stratified condition, wind action may induce unexpectedly large velocity even near the bottom with the magnitude beyond the threshold of the sediment movement. This fact suggests that the wind driven current may cause appreciable sediment transport in a coastal boundary layr.
