The linearized theory of water waves is used to examine the diffraction of an incident wave by a permeable breakwater that consists of a number of distinct elements. Under the assumption that the wavelength is much greater than the thickness, each element is replaced by a thin structure and the permeability is modeled by a suitable boundary condition applied on its surface. The diffracted wave ...

The development along the coastal zone has led to host of problems such as erosion, siltation, flooding, loss resources and destruction fragile marine habitats. erosion threatens zone, which affects people's economic, tourist, recreational life. main reason is due Khan Younis breakwater sea waves working on empty beachy sand, thereby flooding scouring area it ebbs removing part unconsolidated s...

The multi-chamber Oscillating Water Column (OWC) device has recently become more attractive due to its potential high efficiency. In this paper, the hydrodynamic performance of a single-, dual- and triple-chamber OWC-breakwater are investigated experimentally. first instance, quantitative comparisons implemented understand OWC-breakwaters. Specific attention been dedicated capture width ratio (...

Coastal structures were usually considered as stiff in the majority of studies related to wave structure interaction I n certain situations, such impulsive loading on flexible breakwaters, ship hulls, tank walls hydroelasticity can be importance for both dynamics and structural responses Akrish et al. (2018) showed that hydroelastic effects either relax or amplify hydrodynamic characteristics (...

The use of wave energy by converting it into electricity depends on the efficiency converters, which are negatively affected marine factors. Many design flaws can be eliminated at stage and testing devices using its numerical models based application hydrodynamic theory propagation interaction waves with structures. modern computational methods hydrodynamics to determine influence some factors ...

Combining wave energy converters (WECs) with a floating breakwater provides potential approach to help develop commercial-scale power operations. This paper aims design and optimize three-dimensional integrated WEC array by developing numerical model of multi-floating-body coupled system based on flow theory viscous correction in the frequency domain. By analyzing surface elevations around brea...

There is great interest in the restoration and conservation of coastal habitats for protection from flooding and erosion. This is evidenced by the growing number of analyses and reviews of the effectiveness of habitats as natural defences and increasing funding world-wide for nature-based defences-i.e. restoration projects aimed at coastal protection; yet, there is no synthetic information on w...
