One dimensional Boussinesq equations are integrated numerically trough a predictorcorrector
scheme combined with a finite difference – finite volume spatial integration, that allows
classical finite volume Godunov approach to be applied to pure advective terms.
The 1D numerical scheme has been tested with regular waves propagating over a sloping beach in
presence of impermeable breakwaters. The structures were both partially emerged and completely
submerged. The generated waves overtopped the barrier, spreading behind it. The results are shown
and compared with experimental data deducted from literature.
