Abstract
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.
