Two Dimensional (2d) Experimental of Piling up Behind Submerged Break Water

Cyril Bernard Rachman*,Bambang Triatmodjo,Nur Yuwono

This research was done because of the continuous alert of coastal erosion due to sea level rise and also due to the fact that habitats and living beings will be affected. All these will be affected because of a submerged breakwater structure constructed near the shoreline to reduce the effect of strong waves without disturbing the ocean view.

Further on to this, the study will see whether there are other disadvantages of constructing the submerged breakwater or not. A 2D experimental was done consisting of 60 simulations with four different types of submerged breakwater models heights, and one simulation is using no structure. The results were then recorded to get the piling-up of the runnings for the different structures.

What was found out was that the piling-up is influenced by certain parameters. Those parameters are (1) pilingup is influenced by structure parameter in terms of structure depth, Rc and (2) piling-up also influenced by wave parameters in terms of Period, T. From the study, it is concluded that the influenced of piling-up to wave parameters, Rc is directly proportional and with respect to Period, T the piling-up is inversely proportional.
