ORTHONORMAL WAVELET ANALYSIS FOR DEEP-WATER BREAKING WAVES

Nobuhito Mori, Takashi Yasuda

Abstract


This study aims to develop a method using wavelet transform to detect wave breaking event from temporal water surface elevation data. Sudden surface jump associated with breaking wave is regarded as shock wave and shock wavelet spectrum is defined to detect the occurrence of the surface jump. The visual observation of breaking wave crest shows that this method can almost completely detect the occurrence of breaking wave in random wave trains.
