| Summary: | Coastal areas are currently facing serious problems of erosion. Urgent protection is needed in order to cater these alarming problems. Submerged breakwater is one of the protections that can be used to reduce the erosion. This type of breakwater widely used all over the world. This research deals with submerged breakwater that armored with interlocking concrete unit (ICU-V). The objectives of this research are to investigate the relationship between the variables of the factors affecting wave attenuation, to compare the theoretical values and experimental values and to produce an effective and optimum design of submerged breakwaters with interlocking concrete unit (ICU-V). Laboratory experiment on submerged breakwater using interlocking concrete unit (ICU-V) with 108 tests for this research were analyzed. The varied parameters were wave period (T), wave height; water depth (d) and width crest (B). The experiment tests were conducted in a wave flume 23m long and 2 m wide. The result from this laboratory experiment has been compared with the previous researchers. The results shown that the two variables that been investigated in this laboratory experiment which are depth of submergence and crest width do have effect on the wave attenuation. Wave attenuation is inversely proportional with the crest width but directly proportional with the relative crest elevation. Transmission coefficients derived from the experimental results are reasonably comparable with the theoretical values calculated based on Tomasicchio and D'Alessandro. |
