Figure 15. Longshore transport rate for all wave sceanrios.
Figure 15. For 135 locations (A, black line) along Breton Island (0 m contour shown in green), longshore transport rate (B; eq. 1) for each of the 116 wave scenarios (fig. 2) for the no pit case. Red colors indicate northerly transport and blue colors indicate southerly transport. Moving from left to right in (B), the magnitude of transport increases for larger wave scenarios. Because the dominant wave direction for storms is from the south and southeast (fig. 2), there are few large wave scenarios with predominantly southerly directed transport. [m, meters]
