Wave grouping characteristics in nearshore Great Lakes

The recently advanced approach of wavelet transform is applied to the analy sis of wave data measured in the nearshore areas of the Great Lakes. The co nventional spectrum analysis of wave time series in the frequency domain ca n be readily generalized to the frequency and time domain using the wavelet transform. The traditional Fourier transform approach has not been able to directly assess the time localized nature of wave groups. With the applica tion of wavelet transformation, the relatively unexplored wave grouping cha racteristics come to Light as the predominant feature of wave processes. (C ) 2000 Elsevier Science Ltd.
