Shock-like Waves with Finite Amplitudes.

The tidal wave in the Qiantang River, Hangzhou City, China is quite different from that of KdV equation, it is a shock-like wave with a finite amplitude. This phenomenon has mathematicians adjusting their solitary wave models on how such waves behave. This paper applies the variational theory to insight into the energy behave of the tidal wave, which can be modelled by the Benny-Luke equation, and the exp-function method is used to figure out the solution structure. This paper provides a new window for designing energy harvesting devices from the shock-like waves. [ABSTRACT FROM AUTHOR]
