Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on  a laboratory model conducted by Losada et al, cali...

Based on existing construction practices, and the difficulty of sourcing rock armor materials in Philippines, an alternative to conventional rubble mound breakwaters was considered for a beach resort development Cebu, Philippines. A tangent bored pile wall, consisting circular piles placed diametrically along specified alignment, analyzed designed as breakwater. It relies embedment depth soil f...

BACKGROUND: The bioengineering technique used in Germany for erosion control includes a relatively low-cost biodegradable breakwater with wetlands located shoreward. The technique has application for shoreline erosion control on many U.S. reservoirs with dense thickets of young, woody trees, e.g. willow, cottonwood, and alder, located near them since these materials are used in the breakwater. ...

A computationally efficient approximate analytical solution based on the classic solution for diffraction about a semi-infinite breakwater, is developed to assess the wave energy shadow down-wave of a single row array of overtopping type wave energy converters approximated as partially transmitting breakwater segments. The approximations associated with the solution are mitigated by a compariso...

This paper presents the concept and initial tank testing of a novel low profile floating breakwater incorporating energy generation. The breakwater is intended to be anchored parallel to the coast with a beach at the front of the device to rotate the incoming waves towards collector tubes. The water hammer principle is used to harvest the high water particle velocities, charging a rear mounted ...

This paper presents a numerical model for the simulation of solitary wave transformation around a permeable submerged breakwater. The wave-structure interaction is obtained by solving the Volume-Averaged Reynolds-Averaged Navier-Stokes governing equations VARANS and volume of fluid VOF theory. This model is applied to understand the effects of porosity, equivalent mean diameter of porous media,...

Cellular energy production depends on electron transfer (ET) between proteins. In this theoretical study, we investigate the impact of structural and conformational variations on the electronic coupling between the redox proteins methylamine dehydrogenase and amicyanin from Paracoccus denitrificans. We used molecular dynamics simulations to generate configurations over a duration of 40 ns (samp...

Non-breaking tsunami waves run-up on steep slopes can cause severe damages to coastal structures. The estimation of the wave run-up rate caused by tsunami waves are important to understand the performance and safety issues of the breakwater in practice. In this paper, an Incompressible Smoothed Particle Hydrodynamics method (ISPH) method was utilized for the 2DV numerical modeling of nonli...

Submerged breakwaters are one of the shore protective structures. Any discontinuity in these breakwaters causes changes on current parameters including speed and water surface profile. In this paper, discontinuous submerged breakwaters were modelled to investigate the changes in the wave and flow pattern.To investigate the phenomenon, three models including a shore with constant slope, a shore ...
