Experimental Study of Hydrodynamic Effects of Submerged Breakwaters on the Slope

Submerged breakwaters have become increasingly popular due to their multiple functions, which are to protect shoreline or harbor and to prevent beach erosion in the coastal zones. In this paper trapezoidal submerged breakwater in the coastal zones was modeled using a wave flume. Based on the experimental data collected, characteristics of changing wave profile, energy spectrum, statistic and spectrum parameters of regular waves were calculated and analyzed. The result shows that the wave profile becomes strongly asymmetry and wave energy in lower harmonic is transferred into higher harmonic. At the back of submerged breakwater the wave energy rapidly decreases. The higher harmonics generate and intensify near the bottom or when the water depth decreases.
