Abstract
For the marine developments, numerical simulations of the tidal current became very important.The tidal current is influenced by the bay shape, the depth wind, river flow, air temperature, and etc. but systematic parameter studies are not made so much. In this paper, to confirm the applicability of the simulation by multi level model,1)simulations of the supposed rectangular bay and comparisons with the linear theory, and 2) simulations of the Ariake sea and comparisons with the experimental data are made, considering the effects of wind and river flow.As another application, from viewpoint of ocean nourishment,3) sediment transport from the sea bottom layer.
