The Effect of Storm Surge and Tidal Currents to Sediment Transport in The North Ariake Sea, Japan

Tommy Jansen, Koichiro Ohgushi

Abstract :

The Ariake Sea in Japan is a typical semi–enclosed shallow sea being rich in fishery products. The amount of fishery products decrease in recent years. The prediction of tidal flow, wind effect and suspended sediment transport are important. As analytical tools, MIKE3 Hydrodynamic and Mud Transport Model are used. The simulated tidal current are based on the observation at Nagasaki and Typhoon Songda 200418 from 28 August to 7 September 2004. The highest Suspended Sediment Concentration appeared near the river mouth caused by flooding and behavior of Suspended Sediment Concentration from north to south at spring and neap tides. Storm Surge effected the erosion taking place at most areas in north Ariake Sea and influenced the most to suspended sediment during strong wind period
