Smoothed particle hydrodynamics (SPH) is used to simulate both two and three-dimensional cases of wave breaking. A combined SPH-LES type scheme or sub-particle scale (SPS) scheme is used to capture coherent turbulent structures. Results are presented for weakly plunging breaking waves. The 2-D numerical results show that a highly turbulent bore is produced propagating up the beach while generating reverse breaking that precipitates a downbursting-like phenomenon. The initial application of the 3-D scheme to the same problem is presented but the resolution is insufficient to detect reliably coherent turbulent structures. Nevertheless, even the 3-D results suggest the existence of eddies whose primary axis of rotation is near-vertically oriented.
