Abstract
Coastal erosion occurs at several coastal areas in Indonesia. This coastal erosion is urgently needed to handle by constructing the soft and/or hard structures. The hard structure that help to avoid the coastal erosion is breakwater. The rubble-mound breakwater is usually applied since the material, that is needed, is easy to find in Indonesia and is easy to set up in the chosen location. The stable of rubble-mound breakwater is usually constructed based on the condition of non-submerged structure. The aim of this study is to analize the stability on two dimensional submerged rubble-mound breakwater model. The two-dimensional of submerged rubble-mound model is carried out in a flume at Balai Pantai, Ministry of Public Works, Buleleng, Bali, Indonesia. The wave simulation is applied using reguler wave. The armor layer facing the seaward uses tetrapod that placed randomly. The core layer use two variations, i.e., with and without geotube. The slope of the rubble�mound model facing the seaward is 1:1,5. The submerged condition is set up at water level 70 cm. The measured parameters of this study are the wave height period in front of and behind the breakwater structure. The analysis that can be done is the transmission wave. The placement of geotube at core layer help to maintain the stability of the rubble-mound breakwater. This physical model of submerged rubble-mound breakwater is useful as tool aid before construct the breakwater at the coastal to reduce the structural failure.
