Groynes are normally constructed from the coastline, over the beach and some distance into the shoreface (Fig.1). Their effectiveness in trapping sand from the littoral drift depends on their cross-shore extension or, in other … See more The above shoreline developments for various groyne schemes are somewhat simplified as they do not include 2-D or 3-D effects or long-term profile changes. Such effects do, however, occur in connection with groyne schemes. See more Although groynes may protect some shoreline sections, it is obvious from the above that groynes have many disadvantages. Furthermore, it appears that the effectiveness of groynes depends on the type of coast. … See more A groyne field constructed at an eroding shoreline, not covering the entire width of the littoral zone, will only protect the inner part of the coastal profile against erosion.

This effect is most often seen in a headland and bay coastline. Wave energy tends to be concentrated on the headlands hence more erosion, with lower energy levels occurring within the bays and deposition occurring. If the waves break at an angle within the bays, then longshore drift occurs. Types of wave As a wave approaches ... how to say living room in japanese
