【 摘 要 】
The influence of reflection and dissipation on wave-induced mean magnitudes is studied. Starting from linear wave theory the second order quantities are derived in terms of transfer functions considering regular as well as irregular waves. It is shown that any reflective and dissipative natural or artificial structure such as a vegetation field, or an emerged or submerged breakwater, induces spatial variations of the mean quantities such as the mean water level, mass flux, energy flux or radiation stress. The evolution of these magnitudes is analogous to their behavior in the surfzone, showing wave damping and modulation. Compared with the experimental results, the models presented are able to reproduce wave height transformation as well as mean water level variations along the dissipative structures with reasonable accuracy.
