Historically the finite volume methods have been developed for the numerical integration of conservation laws. In this study we present some recent results on the application of such schemes to dispersive PDEs. Namely, we solve numerically a representative of Boussinesq type equations in view of important applications to the coastal hydrodynamics. Snapshots of a moderate wave amplitude runup onto a complex beach are presented along with great lines of the employed numerical method (see D.~Dutykh et al. (2011) for more details).
