In order to protect fragile shoreline and coastal assets during extreme storms, a combined floating breakwater-windbreak has been proposed reduce both wind wave energies in the sheltered area. The 1 km-long breakwater porous hull with internal tubes allow free passage of water; thereby further dissipating energy. deck structure is designed have slope 25 degrees facing upstream side, arrays cyli...

Even though wave run-up is not a new subject, until recently analytical and numerical studies of long wave run-up on a plane beach have failed to identify the existence of resonant regimes. Furthermore, it was a common belief that the leading wave will result in the maximum runup. Stefanakis et al. (2011) underlined the importance of resonant long wave interactions during run-up and run-down. I...

Nonlinear wave run-up on the beach caused by a harmonic wave maker located at some distance from the shore line is studied experimentally. It is revealed that under certain wave excitation frequencies, a significant increase in run-up amplification is observed. It is found that this amplification is due to the excitation of resonant mode in the region between the shoreline and wave maker. Frequ...

Wave impact and run-up onto vertical obstacles constitutes one of the main phenomena which have to be taken into account in the design of coastal structures. From the linear wave theory we know that the wave height on a vertical wall is twice the incident wave amplitude. Weakly nonlinear theories bring some small corrections to this result. However, in the present study we show that certain sim...

Until now, the analysis of long wave run-up on a plane beach has been focused on finding its maximum value, failing to capture the existence of resonant regimes. One-dimensional numerical simulations in the framework of the nonlinear shallow water equations are used to investigate the boundary value problem for plane and nontrivial beaches. Monochromatic waves, as well as virtual wave-gage reco...
