Waves induce flow around reef structures has been difficult to estimate, mainly due to complexity of porous structures and breaking waves conditions. An attempt has been made in this study to model the fluid domain and simplification of the existing structure barrier by a finite volume of fluid method for a three-dimensional Stokes model. The model is capable of simulating free-moving surface boundary conditions, the contribution of undertow, wave asymmetry and bottom boundary drift to sediment transport.

In addition to the present fluid model, a specially shaped submerged structure will be tested in order to observe its hydraulic capability to reduce the offshore waves energy as well as to provide a safe and productive environment for fish. It is expected that the flow created by the structure will be similar to flow around a natural reef so that the submerged structure when deployed may help to shelter marine creatures and accelerate reef reconstruction. The hydraulic parameters such as particle velocities, fluid flows, wave breaking and dissipation of wave energy in the vicinity of reefs are investigated. The results of a two-dimensional reef model using the finite volume method are presented and discussed. Comparison to laboratory measurement will also be discussed in this study.
