WebbA breakwater is a coastal structure (usually a rock and rubble mound structure) parallel or close to the coast. It reduces incoming wave energy, provides a sheltered beach area and shelters vessels from waves and currents. A breakwater typically comprises various stone layers and is typically armoured with large armour stone or … WebbOffshore breakwaters are normally located at a slightly greater water depth than is required for navigation, thus avoiding/minimizing capital dredging and minimizing sedimentation. They are designed: to provide …

WebbAn offshore breakwater can be constructed as a single structure for localized shore protection or as multiple breakwaters to protect a longer section of beach. Spacing between breakwater segments (gap width) should be carefully evaluated by increasing the gap width according to the amount of wave energy behind the breakwaters. WebbThe use of offshore breakwaters in the UK is relatively uncommon with only 6 schemes constructed to date (early 1998). The use of this technology in the UK is examined via a case study of the 8-unit Elmer Beach offshore breakwater scheme which fronts a shingle beach.
