WebJan 1, 2015 · In the tsunami basin, two detached breakwater models (90cm long) made up of stones were placed on a slope of 1:10 and an onshore beach slope was 1:20. The velocity of the flow generated near the shoreline for both cases, with and without detached breakwater models, was measured using current meters. There are two main types of offshore breakwater (also called detached breakwater): single and multiple. Single, as the name suggests, means the breakwater consists of one unbroken barrier, while multiple breakwaters (in numbers anywhere from two to twenty) are positioned with gaps in between (160–980 feet or 50–300 metres). The length of the gap is largely governed by the interacting wavelengths. Breakwaters may be either fixed or floating, and impermeable or perm… s2101
