Table 1.
The nominal and measured parameters of waves. Water depth was fixed at H = 97 cm throughout the tests. (a) The wave period was determined by the period of the paddle in the wave flume. (b) Nominal wave heights were chosen and entered as the required heights to the LabVIEW program. (c) The measured wave height, H, is the real wave height, measured by the wave probes. (d) Wavelength, L, was determined by the wave dispersion relationship [54]. (e) The wave steepness (H/L) was the quotient of measured wave height to wavelength. “NA” indicates instances where the wave parameter was not well defined due to wave breaking and the subsequent generation of harmonics.
