Figure A4-3. For 135 locations (A, black line) along Breton Island (0 m contour shown in green), average longshore transport rate (B, LSTR) calculated by weighting each of the 116 individual scenario results by its frequency of occurrence in the wave climatology (fig. 2). The change in magnitude of the weighted average longshore transport rate (C) with the addition of the pits is less than 30 percent of the baseline values, and the overall pattern in transport is the same (B).
