Offshore Breakwaters in Laboratory and Field

摘要: Small scale model tests for single and multiple offshore breakwaters were performed in a spiral wave basin to examine the effects of their geometric parameters on morphological change vicinity. The results are compared with physical studies reported by others field. All horizontal lengths nondimensionalized respect distance breakwater from original shoreline, X\dB. Three dimensionless variables, X\u*\db(=X\db/X\dB), L\u*\dB(=L\dB/X\dB), G\u*\dB(=G\dB/X\dB), found be important, which X\db, L\dB, G\dB surf zone width, length breakwater, gap spacing between adjacent breakwaters, respectively.
