Figure 9.
The graph illustrates the relationship between the breaker depth index for wave breaking and the dimensionless variable h sub s divided by g T squared. The y-axis, labelled as the breaker depth index, ranges from 0 to approximately 4. The x-axis represents the dimensionless variable, starting from 0 and extending to 0.03. Several curves are present on the graph, each indicating a different value of m, ranging from 0 to 0.20, with corresponding colours: blue for m equals 0, red for m equals 0.01, green for m equals 0.02, pink for m equals 0.03, light blue for m equals 0.05, orange for m equals 0.07, purple for m equals 0.10, teal for m equals 0.15, and brown for m equals 0.20. A vertical dashed line at approximately 0.0273 intersects the x-axis, alongside an annotation pointing to this line indicating E q 5 a.Breaker depth index of a wave breaking in front of a coastal structure, , as a function of and bottom slope inclination, m (without assuming the limiting wave steepness condition)
