WebJun 13, 2024 · In general, the wave amplification rate during shoaling does not follow a power law. When the incident wave is finite, the shoaling amplification becomes faster than that of Green’s law when the ratio of the wavelength to the beach length is small, but becomes slower when the length ratio increases. WebK. G. Lamb and A. Warn-Varnas: Shoaling internal solitary waves 291 add to the limited understanding of the evolution of wave amplitude and currents during shoaling by determining the depths at which maximum amplitudes and currents are at-tained and via comparisons with adiabatic theory. The gener-ation of mode-two waves is also clariﬁed.
