The experiments were organized into four different sets,
according to the configuration of the FB. Four different FB configurations
were examined: (a) single fixed FB, (b) heave motion
FB, (c) single fixed FB with attached front (permeable and impermeable)
plate and (d) double fixed FB. In every set, regular and
irregular waves were generated covering a range of shallow and
intermediate waters (0.04 < d/L < 0.35, d = waterdepth,L =
wavelength). The four configurations are presented in Figs 3–6,
respectively.
