Abstract: A one-year simulation of tide- andwind-driven circulation in the Java Sea, which is one ofthe Indonesian seas located in a tropical area, hasbeen carried out using a three-dimensionalhydrodynamic model incorporating the influence of thewind waves generated at the sea surface. This area isinfluenced by the monsoon climate (east- andwest-monsoon). Six hourly-wind fields at 10 m abovethe sea surface were used as a representative windfield. In other respects, the effect of waves on thethree-dimensional hydrodynamic model has beenrepresented by the surface and bottom stresses. Athird-generation wave model called WAM (WAMDI, 1988)was used to calculate the wave parameters and thewave dependence of the drag coefficient. Thetrajectory of water particles induced by thecalculated velocity fields in the Java Sea was then simulated.In dealing with hazardous phenomena, this modelwill be extended to predict suspended sediment fluxes,particularly those relating to catastrophic changes in seabottom topography and beach erosion. It is also animportant tool for the prediction of storm surge events. Copyright Kluwer Academic Publishers 2000
