Figure 2.
The graph illustrates the relationship between H sub b divided by d sub s on the vertical axis and d sub s over T squared presented in feet per second squared on the horizontal axis. The curves represent different nearshore slopes denoted by variables m ranging from zero point zero to zero point two, with distinct colours for each slope. The graph exhibits a general downward trend, resembling a non-linear function. A boxed annotation points to the curve, indicating it is a non-linear function. The vertical axis ranges from zero to approximately four point five, while the horizontal axis ranges from zero to approximately zero point zero seven.Breaker depth index of a wave breaking in front of a coastal structure, , as a function of bottom slope inclination, m [based on the original Figure 4 in Weggel (1972: p. 427); ]
