Abstract (EN): The authors describe a Petrov-Galerkin finite element method with third-order accuracy for the numerical solution of the Boussinesq equations for weakly nonlinear dispersive water waves in two dimensional horizontal domains. Finite elements are used in both time and space domains. Dispersion correction and a highly selective dissipation mechanism are introduced through additional streamline upwind and cross-stream terms in the weighting functions. Linear interpolation in space is retained and coupled with an implicit one-level time integration scheme. An accuracy and stability analysis is presented. The numerical results are compared to experimental data collected at a wave flume for the propagation of a solitary wave along an horizontal channel and overpassing a vertical cylinder. It is concluded that the proposed finite element method possesses very good features.
