A non-reflective SPH (Smoothed Particle Hydrodynamics) wave flume is developed to study wave transformation over the deep-sea platform reef with a steep reef-face. The left and right boundaries of the flume are modeled using the periodic boundary conditions and a water circulation technology, and a momentum source wave maker is applied to generate the required wave. Wave transformation over the reef-flat is analyzed and compared with the experimental data. The results show that the present SPH model can effectively overcome the non-physical rise of the mean water level in the lagoon and over the reef-flat, which can be observed in the long time simulation with the traditional vertical two-dimensional numerical model. Furthermore, the present model can accurately reproduce the wave breaking process and give a good agreement with the experimental data in terms of the spatial distribution of wave height and wave setup on the reef flat.
