Abstract

Abstract

The wave reflection coefficient frequency spectrum and directional spectrum for concrete shield breakwater and rubble mound breakwater have been investigated through physical model tests.Reflection coefficients of obliqueir regularwaves are analyzed with the modified two-points method(M T PM) proposed.The results show that wave reflection coefficient decreases with increasing of wave frequency and incident angle or decr easing of the structure slope.The reflection coefficient frequent spectrum and its variation with Iribarren number are given.An empirical 3-dimensional reflection coefficient spectrum is suggested,which can be used to illust rate quantitatively the variations of reflection coefficient with incident angle and a non-dimensional characterized parameter Iribarren number for oblique irregular waves.
