Authors: O'Brien, Laura; Renzi, Emiliano; Dias, Frederic; Christodoulides, Paul
Abstract: With an increasing emphasis on renewable energy resources, wave power technology is fast becoming a realistic solution. The
question posed here is whether a nearshore wave energy converter could withstand the force of an incoming tsunami. An analytical 3D
model is developed within a linear theory and applied to an array of fixed plates. The time derivative of the velocity potential allows the
hydrodynamic force to be found. The hydrostatic force can be found from the difference in free surface heights on either side of the device.

Abstract: With an increasing emphasis on renewable energy resources, wave power technology is fast becoming a realistic solution. However, the recent tsunami in Japan was a harsh reminder of the ferocity of the ocean. It is known that tsunamis are nearly undetectable in the open ocean but as the wave approaches the shore its energy is compressed creating large destructive waves. The question posed here is whether a nearshore wave energy converter (WEC) could withstand the force of an incoming tsunami. The analytical 3D model of Renzi and Dias (2012) developed within the framework of a linear theory and applied to an array of fixed plates is used. The time derivative of the velocity potential allows the hydrodynamic force to be calculated.

Abstract: With an increasing emphasis on renewable energy resources, wave power technology is becoming one of the realistic solutions. However, the 2011 tsunami in Japan was a harsh reminder of the ferocity of the ocean. It is known that tsunamis are nearly undetectable in the open ocean but as the wave approaches the shore its energy is compressed, creating large destructive waves. The question posed here is whether an oscillating wave surge converter (OWSC) could withstand the force of an incoming tsunami. Several tools are used to provide an answer: an analytical 3D model developed within the framework of linear theory, a numerical model based on the non-linear shallow water equations and empirical formulas. Numerical results show that run-up and draw-down can be amplified under some circumstances, leading to an OWSC lying on dry ground!
