Breakwaters & Shoreline Protection

Breakwaters Shoreline Protection

Breakwaters can be constructed with one end linked to the shore, in which case they are usually classified as sea walls; otherwise they are positioned offshore from as little as 100 m up to 300–600 m from the original shoreline. There are two main types of offshore breakwater, single and multiple; single as the name suggests means the breakwater consists of one unbroken barrier, which multiple breakwaters (in numbers anywhere from 2-20) are positioned with gaps in between (50–300 m). Length of gap is largely governed by the interacting wavelengths.
