- Recently, a numerical modeling for simulating 2-D wave propagation has been studied by scientists and engineers extensively. This is intended to see how far phenomenon of wave propagation if it's really happened in the nature. Besides that because of impacts from the occurrence of tsunami in the various area in Indonesia generally and in the Aceh Province especially, studies of the phenomenon of tsunami to be increase, and also coastal protection studies by using submerged breakwaters more increase significantly. Therefore in this research is conducted a study of 2-D wave propagation over submerged breakwater An ability of wave high reduction by submerged breakwater inspired from reef which it's having ability in weakening shallow water waves propagate to coastline. Others, also because of a reason of esthetics, breakwaters which emerge to the water surfaces have been assumed bother the fisherman activities. In this research, a 2-D hyperbolic equation is used for the simulation of its wave propagation and open boundary conditions involved for the calculation of wave propagation in its boundaries. An explicit finite different method for second order of accuracies employed for the calculation of its equation approach. Result of this research indicated that by using the 2-D hyperbolic equation, the explicit finite difference method for the second order of accuracies and the open boundary condition method for the condition of its boundaries to be able to simulate the wave propagation of over the submerged breakwater. In this research, dispersion and reflection effects of the submerged breakwater have been shown significantly. And it is available to use the submerged breakwater as a wave reduction in the coast area. Keywords: numerical modeling, 2-D wave propagation, submerged breakwater.
