This report describes evaluation of a two-dimensional Boussinesq- type wave model, BOUSS-2D, with data obtained from two laboratory experiments and two field studies at the islands of Guam and Hawaii, for waves propagating over fringing reefs. The model e...
Finite volume schemes are commonly used to construct approximate solutions to conservation laws. In this study we extend the framework of the finite volume methods to dispersive water wave models, in particular to Boussinesq type systems. We focus mainly on the application of the method to bidirectional nonlinear, dispersive wave ...

This paper deals with traveling wave solutions of the (N+1)-dimensional Boussinesq type equation and of the B(m,n) equation. They are found into explicit form being expressed in some special cases by the Jacobi elliptic function. In the general case they are written into integral form and it turns out that they develop cusp type singularities.
A set of coupled partial differential equations of Boussinesq type are derived in the continuum limit from the equations of motion of Toda lattice with a transversal degree of freedom. Here the numerical stability of a hybrid traveling wave solution of su...
A set of coupled partial differential equations of Boussinesq type are derived in the continuum limit from the equations of motion of Toda lattice with a transversal degree of freedom. Here the numerical stability of a hybrid traveling wave solution of such system (with longitudinal and transversal components) is investigated.

The current generation of operational morphodynamic models is based on the short-wave averaged depth-integrated Reynolds equations. Because the short waves are averaged out, a separate module, the wave driver, is needed to provide the wave-depentdent forcing in the momentum equations. Most operational models use a steady wave driver based on linear theory, ...

A high-order finite volume scheme is developed to numerically integrate a fully nonlinear and weakly dispersive set of Boussinesq-type equations (the so-called Serre equations) (J. Fluid Mech. 1987; 176:117-134; Surveys Geophys. 2004; 25(3-4):315-337). The choice of this discretization strategy is motivated by the fact that this particular set of equations is recasted in a convenient ...

The transition radiation and transition scattering that occur when inhomogeneities are present along the trajectory of a soliton are investigated by developing perturbation theory for a nonlinear equation of the Boussinesq type. It is shown that if a magnetoacoustic soliton propagating at right angles to an external magnetic field in a low-temperature ...
