Longshore Transmission of Reflected Waves

Waves reflected from coastal structures may become trapped by refraction, causing reflected wave energy to arrive at the coastline some distance from the structure. Trapped reflected waves have been previously discussed by Camfield 1982, 1988, and in and in the Shore Protection Manual SPM, 1984. The reflected waves may have a localized effect on coastal processes, and cause localized erosion as the shoreline adjusts its orientation to reach equilibrium with the reflected waves. Reflected waves may also affect recreation, e.g., surfing, and there is an increasing interest to analyze reflected waves.
