Figure 5. Depth of depth-induced wave breaking dissipation.
Figure 5. Depth at which depth-induced wave breaking dissipation (output from SWAN) exceeded 0.01 watt per square meter (W/m2) (dark blue line) at 95 percent of alongshore locations for each wave scenario. Also shown are the depth at which breaking dissipation exceeded 0.001 W/m2 and 0.1 W/m2 (light blue band) and the percentage occurrence (black line) for each scenario. The island platform was defined as the 4 m contour (in pink; fig. 4), and in cases where the threshold of breaking dissipation was exceeded at deeper than 4 m, values from this depth were used in calculating alongshore flux.
