Abstract

Nusa Dua Beach is located in Badung Regency, Bali Province. Nusa Dua beach is experiencing erosion and coastline decline due to wave energy and sediment movement along the coast. Currently, at Nusa Dua Beach, several erosion control efforts have been carried out by building offshore breakwaters, groins, revetments, and sand nourishment. Breakwater can reduce wave height. In this study, the layout of the breakwater was determined on Nusa Dua Beach, Bali Province, in order to reduce wave height and reduce the speed of longshore currents, so as to control erosion and prevent shoreline deterioration. The breakwater which its layout is designed is a low crested breakwater (LCB/PEGAR) with crest elevation at -1 m from MSL. The breakwater is designed not to cause sedimentation so that its layout is about 360 m from the shoreline and has a structure length of 180 m. Three units of breakwater is designed with a distance between structures of 22.5 m. The results of wave modeling show that with the designed layout, the breakwater can reduce the wave height on the beach, which was initially around 2-3 m to about 1 m.
