Abstract

Submerged breakwaters have been widely used for the protection of coastal habitats. However, as with the many designs in the market, there have been mixed reviews on the current array of submerged breakwaters. Hence, there is definitely room for innovations. A multipurpose submerged breakwater (M-Sub) is designed staggered to study the wave transmission effects of its corresponding vortices and turbulence. In its conceptual stage, it is suitable for areas of moderate/low wave energy climate. Besides being a possible solution to coastal erosion, it holds potential as a fish habitat enhancer. This study is designed to investigate the transmissive abilities (in terms of transmission coefficient, K1) of this innovative breakwater shape. The objective is to obtain experimental data and wave attenuating abilities of the model subjected to regular and random waves in an array of wave parameters and structure porosity.Results from the 144 tests conducted revealed good resemblance with the expected trend calculated using d'Angremond. TheM-Sub worked best for the wave height of 0.18 m and wave period of 1.12 s, whereas its porous version was found to return a lower K1 value when tested with 0.16 m waves. Nevertheless, additional experiments should be conducted to enhance the initial findings by including more variables such as wave variability and structure configurations.
