Figure 17. A diagram showing various sand-wave profiles of waves on shoal north of Plum Island.

Figure 17. Sand-wave profiles of waves on shoal north of Plum Island. Arrows show direction of net sediment transport. Profile A-A' shows waves with asymmetries suggesting a westward net sediment transport. Profiles B-B' and C-C' show waves with asymmetries suggesting an eastward net sediment transport. Profile D-D' shows waves that are symmetrical and are probably not moving. Vertical exaggeration is 6X in profiles A-A', B-B', and C-C' and 7X in profile D-D'. Locations of profiles shown in figure 16.
