A submerged horizontal plate type breakwater is pointed out as an efficient wave protection device for cage culture in marine fishery. In order to reveal the wave elimination principle of this type breakwater, boundary element method is utilized to investigate this problem. The flow field and the trajectory of water particles are studied carefully. The flow field analysis shows that: the intera...

Breakwaters are marine structures useful for the safe harbouring of ships and the protection of harbours from sedimentation and coasts from erosion. Breakwater monitoring is then a critical part of coastal engineering research, since it is crucial to know the state of a breakwater at any time in order to evaluate its health in terms of stability and plan restoration works. In this paper we pres...

Shorelines at the interface of marine, estuarine and terrestrial biomes are among the most degraded and threatened habitats in the coastal zone because of their sensitivity to sea level rise, storms and increased human utilization. Previous efforts to protect shorelines have largely involved constructing bulkheads and seawalls which can detrimentally affect nearshore habitats. Recently, efforts...

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 ...

Composite vertical breakwaters are coastal structures used to defend port basins from waves in intermediate and deep water conditions. In order safely use the inner side of harbors, it is important limit wave overtopping. Parapet walls for this purpose. To improve hydraulic efficiency parapet wall with a fixed crown height, can be shaped giving rise recurved overhand toward sea. Its function de...

West Palm Beach (Florida), ISSN 0749-0208. The evolution of the coast of Hawke’s Bay, New Zealand, and its erosion problems have been governed by multiple factors, including its tectonic setting with an earthquake in 193...
