The Determination of Wave Group Parameters from the Resolution of Incident and Reflected Waves.

Abstract

Laboratory tests conducted to determine the effects of wave groups on rubble mound breakwater stability are analyzed. A literature review outlining the controversy regarding whether or not wave groups effect breakwater stability is given. Resolution of this controversy is proposed using two independent parameters that characterize wave groups. The two parameters are an envelope exceedance coefficient a and spectral shape gamma. The incident time series must be known to compute alpha, and an algorithm is given that will resolve incident and reflected wave time series from closely spaced wave gauges. The digital to analog simulation of laboratory waves with specified wave group characteristics is reviewed. It is recommended that further studies be conducted to parameterize the envelope exceedance coefficient alpha with a non-biased groupiness factor. (MM)
