Boussinesq-type modeling in surf zone using mesh-less least-square-based finite difference method

Combining mesh-less finite difference method and least square approximation, a new numerical model is developed for highly dispersive and fully nonlinear Boussinesq equations in two horizontal dimensions.

Zusammenfassung:Combining mesh-less finite difference method and least square approximation, a new numerical model is developed for highly dispersive and fully nonlinear Boussinesq equations in two horizontal dimensions. The 3 super(rd) order truncated series solution of the Laplace equation is employed to approximate the velocity distribution in the vertical plane. The linear properties of the wave model are discussed with Fourier analysis. It is shown that the model is suitable to predict the propagation of water waves at the range of 0
