contents A numerical study of the 2D Amick-Schonbek Boussinesq system is presented. Numerical evidence is given for the transverse stability of the 1D solitary waves that are line solitary waves of the 2D equations. It is shown that initial data not satisfying the non-cavitation condition can lead to the formation of a gradient catastrophe in finite time. The numerical propagation of localised smooth initial data does not lead to the formation of stable structures localised in both spatial directions. For initial data satisfying the non-cavitation condition, smooth solutions appear to exist for all times.
