Daftar Isi:
- Beach damage is a serious problem which requires prompt action from the government. Adding more sediment to the beach (beach nourishment) is one of the efforts to cope with the problem. However, the sediment filled is usually carried away by the wave, which consequently brings maintenance costs for dealing with the sandpile during certain periods, as well as the need for large volume of excavation. One of the alternatives to reduce the loss of the sediment pile is by constructing off-shore submerged structure with the crestof the structure is set submerged and made from geotube. The objective of this study was to identify the influence of wave steepness and the submerged structure to the beach profile formed behind the structure. The physical model test was carried out to the sand of Tanjung Ann beach (d50=1.47 mm) under two conditions: without the submerged structure and with the geotube submerged structure within wave period (1
