Ocean waves play an important role in the marine ecosystem but can also cause damage to coastal infrastructure. One solution to reduce the negative impact of waves is to use submerged beams. This study focuses on submerged beams and aims to examine wave propagation through submerged beams with the wave type being monochromatic waves. The propagation is modeled with initial and boundary values of the linearized Laplace equation so as to obtain the propagating monochromatic wave pattern. Simulations carried out using MATLAB software show that the monochromatic wave pattern propagates depending on the depth, which is related to the length and frequency of the wave. In the event that there is a difference in height, especially if there is a submerged beam, the change in wave amplitude before and after passing through the beam will be observed. The results show a relationship between the dimensions of the beam and the change in wave amplitude.
