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 ...

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

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.

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 field with a submerged porous breakwater

Journal of the Chinese Institute of Engineers, 2003
Abstract The flow field of linear waves passing a submerged porous breakwater has been solved analytically in this paper. The permeable breakwater is considered to be aniso‐tropic but homogeneous. The hypothesis of equivalent work is assumed in the porous field to ensure the existence of velocity potential in an irrotational flow field.

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.

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 Diffraction through Submerged Breakwaters

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1993
The water‐wave interaction with submerged breakwaters is examined to determine the reflection and transmission coefficients. Three types of breakwaters are considered, namely, a submerged breakwater extending from the sea bed until below the waterline, a breakwater extending from above the seawater to some distance below, and a breakwater extending all

Wave Transmission over Submerged Breakwaters

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1989
Monochromatic wave reflection and transmission over a submerged impermeable breakwater is predicted numerically by slightly modifying the numerical model developed previously for predicting wave reflection and run‐up on rough or smooth impermeable slopes. The slight modification is related to the landward boundary condition required for the transmitted
