| dc.description.abstract | In recent years, Indonesia beach is faced to erosion and abrasion problems. One of an alternative can be applied to solve these
problems is beach nourishment. Beach nourishment need large volume of sediment filler. For reducing of sediment filler, then
the sediment filler is protected by submerged structure. The problems, beach profile at behind submerged structure after beach
nourishment reach to equilibrium condition is not yet understood. The objective of this research is to indentify beach profile
behind submerged structure for several wave and structure parameters. This research conducted in Hydraulic and Hydrology
Laboratory, Engineering Research Centre, Gadjah Mada University using of physical modeling. Equilibrium beach profile
form at behind submerged structure influenced by deep water wave steepness (Ho/Lo) and depth relative (Rc/hs). The greater
value of Ho/Lo and Rc/hs the greater the retreat of beach profile. Wave steepness can be used to indentify direction of
sediment movement. | en_US |
