TIME AND FREQUENCY DOMAIN ANALYSIS OF SHALLOW WATER WAVES ON A SLOPE

D.H. Swart, J.B. Crowley

Abstract


Classical time and frequency domain analyses give results with limited physical meaning when applied to shallow water cases. Lower heights and periods than suggested by the actual data are obtained via these analyses. It appears that slope effects make waves less non-linear for steeper than for flatter slopes. One can obtain useful trends by making use of higher-order analyses, utilising higher-order, asymmetrical waves of the covocoidal type as an example.
