ABSTRACT: 

This study aims to examine and obtain the magnitude of the influence of several factors on the magnitude of the increase in height wave deformation (Hdf). The research was conducted at the Coastal Engineering Research Laboratory, Faculty of Engineering, Hasanuddin University, Indonesia. Experimental research on 3D physical models in a 10m x 15m wave pool with a depth of 1.0m. Two types of WCSP-DS models with and without wave energy centering walls (WFW), at the geometric scale of 1:20, were simulated with 3 kinds of wave heights and periods (H and T), 5 kinds of freeboard heights (Fb) on 3 kinds positions of elevation of the water level in relation to the vertical wall of the model (d/z). The results showed that the model with and without a wave-focused wall (WFW) experienced a significant increase in wave height from P1 to P11, the installation of the wave-focused wall (WFW) significantly increased the height of the waves entering the models WCSP- DS. The position of elevation of the water level in relation to the vertical wall of the model (d/z) that has the greatest influence on the increase in wave height is d/z = 1.143. The freeboard height (Fb) has no significant effect on the deformation height wave that occurs.  The wave from point P1 to P11 becomes higher in P11, this indicates a superposition of the incident wave and the reflected wave which produces a standing wave.
