Wave reflections from breakwaters
A new method is presented for estimating the reflection of a random, multi-directional sea from a coastal structure. The technique is applicable to an array of wave gauges of arbitrary geometry deployed seaward of the reflector. An expansion for small oblique wave incidence angles is used to derive …

The underscour of rubble mound breakwaters by wave action
Rubble mound seawalls, groins and breakwaters are still the most common type of shore-protection structures currently in use. Major reasons include: easiness to construct and repair, flexible with respect to settlement, favourable wave energy dissipation, fitness for any water depth and foundation, …

Three-Dimensional Analysis of Moored Cylinders Used as Breakwaters
… frequencies, the use of moored cylinders as breakwaters is considered numerically using linear three-dimensional analysis. The breakwater can be used by itself for protection of small structures or as a series of cylinders to protect a harbor, shoreline, or moored vessel from the destructive …

Investigation Into Snap Loading of Cables Used in Moored Breakwaters
… to investigate snap loads in mooring lines. Breakwaters are structures used to attenuate or eliminate waves and protect shorelines, harbors, and other natural and man-made marine structures from wave damage. The breakwater in this investigation is modeled both as a point mass and as a rigid …

Waves Generated by Moving Vessels and Cnoidal Wave Interactions with Either a Partially-submerged Porous Barrier or a Mixed Partially-submerged and Submerged Dual Porous-Barrier System
… between cnoidal waves and two types of porous breakwaters. One is a partially submerged porous barrier and the other one is a dual-barrier system consisting of a complete submerged frontal porous wall and a partially submerged rear porous wall. For both breakwater systems, the unknown …

A comparison of durability and recruitment for reef mimics constructed from marine concrete and CaCO₃-enriched concrete
… and marine infrastructure, such as seawalls, breakwaters, have replaced natural intertidal, subtidal, and benthic habitats along many coastlines. Coastal infrastructure has a multitude of impacts on biodiversity and ecosystem functioning. The habitat provided by man-made coastal infrastructure …

Two-Dimensional Analysis of Stacked Geosynthetic Tubes
… are used in a variety of applications including breakwaters, groins, and temporary levees. This thesis considers single and stacked geosynthetic tubes resting on rigid and deformable foundations. A two-dimensional analysis is performed on the cross-section of a very long tube. The program …

Comportamiento funcional y ambiental de los diques exentos de baja cota de coronación y su importancia en la ingeniería de costas
… building of structures, amongst which detached breakwaters play a major role. Detached breakwaters are artificial structures, inspired on the coastal natural formations. These structures are generally parallel to the coastline, protecting a certain stretch from wave action and being able to …

Green water and loading on high speed containerships
… was also conducted on a series of rectangular breakwaters that were fitted on the forecastle deck. Changes in water behaviour and loading following changes in the breakwater were well reflected. This implied that instead of a rectangular breakwater, the simulation model could also be applied to …

Experimental Analysis of the Interaction of Water Waves With Flexible Structures
… water waves with flexible structures acting as breakwaters was carried out. Wave profiles, mapped out by water level measuring transducers, were studied to provide information on the performance of different breakwater models. A new signal analysis procedure for determining reflection …

The potential alternative uses of dredged material in the Humber Estuary
… potentially be used for the creation of berm breakwaters within the estuary in order to protect the shore and flood defences behind from erosion and the continuation of disposal within the estuary.Capital dredging occurs rarely in order to create new channels or berths for new or expanding …

Quantifying biotic interactions with inshore subtidal structures: comparisons between artificial and natural reefs
… for future artificial structures such as breakwaters.

Finite element analysis of cellular structures subjected to wave loads
… or breakwater structures. When used as breakwaters, the metal fatigue can become a possible mode of failure for cellular structures due to the cyclic unbalanced lateral loads imposed by the wave action;This study was initiated as an investigation of the cell failures of the Calumet …
