The drift occurs due to waves meeting the beach at an oblique . tombolo, one or more sandbars or spits that connect an island to the mainland. Erosional coasts are characterized by features of accumulated sand/pebble/rock that are eroded elsewhere and deposited on shore where longshore currents slow. Wave diffraction and refraction The wave pattern created by this water movement causes a convergence of longshore drift on the opposite side of the island. This is clearly evident in the Tofino area of Vancouver Island (Figure 17.1), where erosion is the predominant process on the rocky headlands, while depositional processes predominate within the bays.
