Armor Stability on Submerged Breakwaters

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1992
Armor stability on submerged conventional breakwaters is examined using a hybrid method based on experimental, numerical, and empirical results. Four test runs are conducted to measure the horizontal fluid velocities and free-surface elevations over a submerged breakwater caused by a solitary wave.

Modelling of waves and currents around submerged breakwaters

Coastal Engineering, 2005
Abstract Recent experimental data collected during the DELOS project are used to validate two approaches for simulating waves and currents in the vicinity of submerged breakwaters. The first approach is a phase-averaged method in which a wave model is used to simulate wave transformation and calculate radiation stresses, while a flow model (2 ...

Wave forces on submerged, alternately submerged, and emerged semicircular breakwaters

Coastal Engineering, 2003
The wave forces acting on semicircular breakwaters are studied by using a numerical model based on a hybrid method of boundary element method (BEM) and finite difference method (FDM) in this paper. Three typical hydrodynamic statuses of submerged, alternately submerged, and emerged conditions of the semicircular breakwater are taken into account.

Wave Reflection at Submerged Breakwaters

2009
Several types of structures are used in Coastal Engineering with the aim of preventing shoreline erosion, such as groynes, detached breakwaters, submerged breakwaters, etc. Submerged breakwaters have the advantage of their minimal visual impact, which has made them ever more popular (Chang & Liou, 2007).

The damping action of submerged breakwaters

Eos, Transactions American Geophysical Union, 1951
The results of an experimental investigation on the damping action of submerged rectangular breakwaters are presented. The experimental data also are compared with published theories. A new theory is presented which compares more favorably with the experiments than the previous theories.

On the tsunami wave—submerged breakwater interaction

AIP Conference Proceedings, 2008
The tsunami wave loads on a submerged rigid breakwater are inertial. It is the result arising from the simple calculation method here proposed, and it is confirmed by the comparison with results obtained by other researchers. The method is based on the estimate of the speed drop of the tsunami wave passing over the breakwater.

Hydrodynamic conditions in a submerged porous breakwater

Ocean Engineering, 2019
Abstract In the present work the applicability of an extended Boussinesq-type model in simulating wave propagation over submerged porous breakwaters, as well as predicting the velocity distribution inside them was studied. The basic solver is able to reproduce wave propagation in practically any water depth over mild sloping bottom. Extension of this

Numerical prediction of performance of submerged breakwaters

Ocean Engineering, 2005
Abstract The results of a numerical model study on the transmission characteristics of a submerged breakwater are presented. Study aimed to determine the effect of depth of submergence, crest width, initial wave conditions and material properties on the transmission characteristics of the submerged breakwater.

Wave modelling in the vicinity of submerged breakwaters

Coastal Engineering, 2006
Abstract This paper describes a simple method for modelling wave breaking over submerged structures, with the view of using such modelling approach in a coastal area morphodynamic modelling system. A dominant mechanism for dissipating wave energy over a submerged breakwater is depth-limited wave breaking.
