Hydrodynamic model with wave-current interaction in coastal regions

Abstract

The effects of wave–current interaction on the hydrodynamics in coastal regions are investigated. A modified Grant–Madsen analytical model is incorporated into the Princeton Ocean Model (POM) to describe the wave–current interaction. The model is applied to the Singapore Straits for the prediction of tide and wind driven circulation. The simulation results confirm that high shear velocity within the wave bottom boundary layer produces high levels of turbulence intensities. The strong turbulence intensities within the thin wave bottom boundary layer in turn affect the currents through increased bottom resistance.
