Abstract

The theoretical damping coefficients of the sponge layer are derived for Boussinesq equations. Numerical experiments show that the coefficients work efficiently to damp the energy of outgoing waves. The present result differs from former researches using empirical parameters to control the effect of the sponge layer. It is found that the values of damping coefficients increase with the increase of the relative water depth. The numerical results for wave propagating over a submerged bar bathymetry are fairly compared with experimental data.
