... collectively offer cost savings and enhance their commercial viability for harnessing wave energy. This study performs power take-off (PTO) optimization for a wave energy converter (WEC) consisting of a vertical cylinder placed near a vertical seawall in irregular waves. The power take-off system is connected...

... are described by the nonlinear empirical formula. The presented model is validated and applied to investigate the effect of the porous media on wave dissipation. Two cases are investigated, i.e., the solitary wave runup on a permeable layer beach, and the wave impact on a seawall sheltered by porous media...

... ABSTRACT The utilization of recurves on vertical seawalls reduces overtopping without drastic increases in the structures’ freeboard. As part of ISOPE22 blind test challenge, an in-house developed computational fluid dynamics code is used to simulate the breaking of waves on a vertical seawall...

... ABSTRACT Seawall is one of the most important coastal infrastructures to withstand and reduce the harm of extreme sea condition. However, the strong interaction between seawall and waves in extreme weather is easy to cause instability and fracture of the artificial protective block...

...) proposed a set of empirical formulae which uses the equivalent offshore wave height for wave runup and overtopping on sloping and vertical seawalls. Both these empirical formulae were based on the CLASH datasets (CLASH project, 2009). By the way, Goda (1975) drew a set of design diagrams...

... ABSTRACT In very shallow areas, the possibility that coastal dikes and seawalls is destroyed by waves smaller than the design wave is high. Many field cases indicated that the main reasons of the failures of the structures were the scour in the front of the structures and the sand outflow from...

... ABSTRACT Future climate change will possibly cause high storm surges and high waves larger than the design level. In such severe conditions, unexpected failures of coastal structures can occur. Gravity seawalls with parapets are commonly used in coastal areas. Above all, a caisson type seawall...
