Abstract

Understanding soil dynamics in coastal structure locality is significant to evaluate the performance of coastal structures and predict the changes in coastal dynamics caused by a specific structure. Changes in sea-level can cause soil dynamic response around a submerged rubble-mound breakwater. This study analysed the sedimentation that occurred in front of the submerged rubble-mound breakwater through laboratory tests. The submerged rubble-mound breakwater was carried out with a length of 750 cm using the main protective layer of Dolos with a scale of 1:10 and the core layer using Geotube. The wave simulation used daily and extreme waves. The sedimentation research area was in front of the rubble-mound breakwater with a length of 750 cm and a width of 200 cm. The observation points were determined by dividing the research area by 50 cm in the length direction and 50 cm in the width direction. All observation points in the sedimentation study area were analysed and determined points that experienced scouring/deposition due to daily and extreme waves. The results showed that the largest scour occurred in the outer side of study area facing the incident waves, both due to simulations of daily waves and extreme waves. Further research will review the effect of sedimentation on the stability of the submerged rubble-mound breakwater.
