Wave Propagation Past a Pile-Restrained Floating Breakwater

Abstract: The present paper describes a numerical and experimental study of wave propagation past a pile-restrained floating breakwater. The numerical model is based on two-dimensional wave diffraction theory for wave interaction with a long horizontal cylinder and is applied to the common case of a rectangular-section breakwater subjected to normally incident waves. Comparisons with experimental measurements show excellent agreement and the effect of a gap between the piles and the breakwater is discussed. Relevant results for the wave transmission and heave motion of the breakwater in deep water are presented as functions of the relative wave frequency for various beam to draft ratios. *ISOPE Member.

Interim development of a numerical wave flume for maritime structure design

Abstract: This paper describes interim development of a numerical wave flume for practical use in designing maritime structures. The flume is based on a 2-D numerical wave simulation using a NASA-VOF method particularly selected because it can reproduce highly nonlinear wave profiles against various structures, e. g., impact of a breaking wave on a vertical wall. During fiscal years 1998 to 2000, a cooperative research group has been tasked with this project, having almost completed the associated computer code in 1998 and studied application of the numerical wave flume for practical design of various types of coastal structures.

Computational Model for Wave Attenuation by Flexible Vegetation

Abstract: Coastal vegetation has a well-known effect of attenuating waves; however, quantifiable measures of attenuation for general wave and vegetation scenarios are not well known, so field and laboratory studies must be performed for individual setups. The standard practice of performing these studies for such scenarios is extremely expensive, and it is difficult to change parameters and setups. We presented and validated a computational model for a wave flume that can be used for studies of wave attenuation over flexible vegetation based on the previously developed immersed-structure method for fluid–vegetation interaction, thereby augmenting field and laboratory studies with a more-flexible and less-expensive alternative. The main advantage of this computational framework is that almost all terms are derived from first principles without requiring a large number of empirically determined parameters. A series of computational experiments were performed, and an analysis of the wave attenuation with respect to wave heights, spectra, and energy was conducted. Results were compared to results from experiments that the computational wave flume was designed to replicate.
