The Influence of Crest Width and Working States on Wave Transmission of Pile–Rock Breakwaters in the Coastal Mekong Delta

open access: yesJournal of Marine Science and Engineering, 2022
The coastline of the Ca Mau and Kien Giang provinces in the Vietnamese Mekong Delta has been severely eroded in recent decades. Pile–Rock Breakwaters (PRBWs) are among the most widely adopted structures for controlling shoreline erosion in this region ...

On Formulae for Wave Transmission at Submerged and Low-Crested Breakwaters

open access: yesJournal of Marine Science and Engineering, 2022
Submerged and low-crested breakwaters are nearshore barriers with an underwater or slightly emergent crest, designed to reduce the energy of wave attacks and, consequently, to protect the coast from erosion and flooding. Their performance in reducing the

Efficiency and Wave Run-Up of Porous Breakwater with Sloping Deck

open access: yesJournal of Marine Science and Engineering, 2022
In order to protect fragile shoreline and coastal assets during extreme storms, a combined floating breakwater-windbreak has been proposed to reduce both wind and wave energies in the sheltered area.

Unidirectional Wave Propagation in Low-Symmetric Colloidal Photonic-Crystal Heterostructures

open access: yesNanomaterials, 2015
We show theoretically that photonic crystals consisting of colloidal spheres exhibit unidirectional wave propagation and one-way frequency band gaps without breaking time-reversal symmetry via, e.g., the application of an external magnetic field or the ...
