Abstract One of the efforts to improve successful in handling coastal erosion is develop a protection structure be called as PEGAR, an acronym Pemecah Gelombang Ambang Rendah or Low-Crested Breakwater (hereinafter referred LCB). The use geotextile tubes filled with sand LCB construction has been widely practiced since 2010. LCBs play role breaking waves and dampening their energy before reachin...

Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...
