خلاصه مقاله:
Model investigations have been executed in using irregular waves acting on smooth sloping structures inclined 1:3. Analyzing composite spectra in front of the structure the following results are found: (1) A set of partial standing waves is present in front of the structure coincidentally. (2) Each partial clapotis is composed of a number of bound frequency components disposing of an anom alous ispersion property. (3) Reflection coefficients increase with the frequency decreasing. (4) Component clapotis waves are shifted in the upslope direction with frequency increasing. (5) Relative shift of superimposed component clapotis is in accordance with increasing asymmetry of breaking waves.
