An artificial spur-and-groove (SAG) reef formation designed to perform as a submerged breakwater was studied. Not only do natural SAG reefs effectively attenuate waves, but they also create important circulation within the system that encourages success of corals and overall ecosystem. Modular components were developed imported into CFD software FLOW-3D® HYDRO test wave-structure interaction wh...

This work provides a novel approach that combines computational fluid dynamics (CFD) with solid mechanics (CSM) to dynamically simulate the fully coupled hydroelastic interaction between nonlinear ocean waves and submerged horizontal plate breakwater (SHPB). Based on systematic series of simulations, it is shown wave damping performance an SHPB can be evidently improved by appropriate extent de...
