A hydraulic model test,this research investigate the deformation of the wave field caused by the changes in slope bottom when regular wave passes through a submerged breakwater. In this experiment,we aim to discuss the phenomenon of refraction,diffraction,wave height change and wave transformation in wave field behind the submerged breakwater while the waves in diffrernt incident angles, wave height and periods.
Then we used measurement results plotted as two-dimensional and three-dimensional charts. Therefore, the further understanding of the wave's deformation in wave field near the submerged breakwater can be achieved. Based on experiments,it is found that the wave transformation and wave height change were found in the back of the submerged breakwater because of the reftation and diffraction. Furthermore,it indicated that the phenomenon of focus from long period waves was more significant than the one from short period wave.
