【 摘 要 】

This paper describes a deterministic modelling system under development at the Institute of Fluid Mechanics in Hannover to simulate three dimensional wave induced currents and the morphological evolution in the nearshore region. It is basically a coupling of a 2d Boussinesq wave model which predicts the wave motion along the horizontal direction with a 3d hydrodynamic, sediment transport and morphodynamic models that simulate the time averaged wave induced currents and the associated changes in the bathymetry due to sediment transport. It is intended to improve the understanding of morphological processes, investigate the impact of sea level rises due to climate change, study extreme events and assess in the selection of cost effective measures for coastal protection. Results of a demonstration of the simulation of the wave induced currents along a nearshore region in the Baltic Sea are shown.
