Abstract

A series of 140 physical experiments (scale 1/15) have been carried out to test 4 models of unconventional submerged breakwater in hydraulic wave tank. Recorded data have been anaylized and evaluated to define key factors influence transmission coefficency K_t, as the result an empirical equation of K_t has been proposed. The outcome has also shown that not only structural geometry but also oceanographic conditions (H_s, T_p), submerged level and also wave impact on slope via wave slope parameter (s_m) could alternate wave dissipitation coefficient of the unconventional submerged breakwater.
