This paper and its companion Higuera et al. (2014-this issue) introduce the formulation of Volume-Averaged Reynolds-Averaged Navier-Stokes (VARANS) equations in OpenFOAM (R) to simulate two-phase flow through porous media. This new implementation, so-called IHFOAM, corrects the limitations of the original OpenFOAM (R) code. An innovative hybrid methodology (2D-3D) is presented to optimize the simulation time needed to assess the three-dimensional effects of wave interaction with coastal structures. The combined use of a 2D and a 3D model enables the practical application of the 3D VARANS code to simulate real cases, contributing to a significant speed-up. This is highly convenient and especially suitable for non-conventional structures, as it overcomes the limitations inherent to applying semi-empirical formulations out of their range or 2D simulations only. A detailed study of stability and overtopping for a 3D porous high-mound breakwater at prototype scale subjected to oblique irregular (random) waves is carried out. Pressure around the caissons, overtopping discharge rate and turbulent magnitudes are presented in three dimensions. The mean pressure laws present a high degree of accordance with the formulation provided by Goda-Takahashi. Furthermore, local effects due to three-dimensional processes play a significant role, especially close to the breakwater head. (C) 2013 Elsevier B.V. All rights reserved.
