Hydrodynamic performance of pile-supported OWC-type structures as breakwaters : an experimental study
TL;DR: In this paper, the authors investigated the hydrodynamic performance of a pile-supported OWC structure as a breakwater, for which the air-flow through a small opening in the top cover contributes to energy extraction from waves and reduction in transmission coefficients.

Estimation of friction coefficient for double walled permeable vertical breakwater
TL;DR: In this article, the authors derived an empirical formula for determining the friction coefficient of a double walled permeable vertical breakwater in terms of variables representing the porosities of seaward side and shoreward side vertical walls, gap between the walls and depth of water.

Wave attenuation and flow kinematics of an inclined thin plate acting as an alternative coastal protection structure
TL;DR: In this paper, the authors present the results of a 2D experimental model application of an alternative environment-friendly coastal structure, an inclined thin plate (ITP), and the primary objectives of this study were to understand (a) wave energy dissipation mechanism of ITP, (b) wave attenuation performance, and (c) the influence of the ITP on water particle (orbital) velocity characteristics.

The Measurement of Incident and Reflected Spectra Using a Least squares Method
Etienne Mansard,E.R. Funke +1 more
TL;DR: In this article, a least square method to separate the incident and reflected spectra from the measured coexisting spectra is presented, which requires a simultaneous measurement of the waves at three positions in the flume which are in reasonable proximity to each other and are on a line parallel to the direction of wave propagation.

Wave Interactions with Vertical Slotted Barrier
TL;DR: In this article, the authors presented a numerical model of wave interactions with a thin vertical slotted barrier extending from the water surface to some distance above the seabed, and described laboratory tests undertaken to assess the numerical model.

Propagation of oblique incident waves past rigid vertical thin barriers
TL;DR: In this paper, the linear theory for waves impinging obliquely on a vertical thin barrier is examined, and the theoretical solutions are obtained by an eigenfunction expansion method for the transmission and reflection coefficients.

Wave interactions with double slotted barriers
TL;DR: In this article, the authors presented the numerical calculation of wave interactions with a pair of thin vertical slotted barriers extending from the water surface to some distance above the seabed, and described laboratory tests undertaken to assess the numerical model.
