For simplicity, v is used instead of v,/, in Figure and hereafter. Relative laser depth, rd = djldj, is the ratio of the depth of the laser to the depth at the toe, measured from the still water level. As noted by Sawaragi et al. (1982), maximum non-dimensional velocities commonly occurred for collapsing to plunging breaking waves. Pilarczyk and Den Boer (1983) showed minimum stability for 1V:2H slope occurred for ^ = In this case, this point occurs at {HIL^'''^ = , which is near the 21.
