We have already presented a new type of reflection wave dissipater, which has a curtain wall in front of the vertical seawall. The mechanism of the dissipater is to enhance vortex flows around the lower edge of curtain wall by the use of piston mode wave resonance in the water chamber. In order to expand the usage of the dissipater to the sea with comparatively large tidal difference, performan...

A combined BEM-FEM model has been developed to simulate the dynamic interaction between non-linear waves and an impermeable seawall with a submerged rubble toe over a sand seabed. A poro-elastic finite element model has been developed and used under the surface pressure computed by the BEM-FEM model. Modified Navier-Stokes equations are used to solve the flow inside the porous media and Biot's ...

In planning the construction of a seawall, it is necessary to consider several things, such as incoming waves, types defensive units, and economic factors. So for type size armor unit used, expected that structure will only experience minimal damage. addition, there are other considerations, wave reflection by structure. port area, with low needed keep anchored pool calm. this study, experiment...

Anchored Large Woody Debris (LWD) is increasingly being used as one of several nature-based coastal protection strategies along the north-western coasts Canada and US. As an alternative to conventional hard armoring (e.g., seawalls), its usage widely considered be less harmful ecosystem while maintaining ability protect beaches against wave attack erosion. The effects seawalls on have been exte...
