The paper presents a hybrid scheme for the solution of 2DH extended
Boussinesq equations. The finite volume method is applied to the
advective part of the equations, while dispersive and source terms are
discretized by the finite difference technique. To validate the numerical
model, a classical refraction-diffraction test is proposed. Special
attention is devoted to verify the shock-capturing capabilities of the
scheme: the model is applied to one- and two- dimensional runup test
cases with good results, showing that no ad hoc treatment is required at
the shoreline.
