Abstract: The superposition of tidal and wave induced currents is a typical feature of the coastal zone, producing a hydrodynamic environment of great complexity. These currents interact in a highly non-linear manner to produce turbulent boundary layer velocity and instantaneous bed friction force vectors that fluctuate both in magnitude and direction Given this complexity, the development of effective analytical and numerical models for coastal process prediction must continue to depend heavily on data and observations from laboratory and field experiments for calibration and validation purposes
