NUMERICAL SIMULATIONS ON THE INFLUENCE OF THE LONG-TERM FLUCTUATIN OF SEA LEVEL DEPARTURE ON SAND WAVES IN THE KANMON WATERWAY

Abstract

 In this study, the numerical simulations of tidal current and sediment transport in the Kanmon Waterway were performed by using a numerical model FVCOM (Finite Volume Coastal Ocean Model (Chen et al. 2003)), in order to discuss the influence of the sea level departure on the sand waves. The numerical simulatin results suggested that the spatial difference of sea level departure in Kanmon strait slightly changes the tidal current around Tanoura area, and consequently affects the development of sand waves.
