Abstract

Abstract

The interactions between regular surface waves and a surface-pitching slotted barrier are investigated both analytically and experimentally. A quas-i linear theory was developed using the eigenfunction expansion method. The energy dissipation within the barriers was modeled by a quadratic friction factor, and an equivalent linear dissipation coefficient, which is depth-varying, wave-height dependent, was introduced to linearize the matching condition at the surface-pitching barrier. By comparison the theoretical results with laboratory experiments, it is shown that the present method can satisfactorily predict the variation of the reflection and transmission coefficients with wave height.
