The Boussinesq equation is a nonlinear dispersive wave equation modelling water propagating in channels. Its rich mathematical properties being an integrable system enable us to derive approximative formulas for solutions valid for large times with decaying initial data defined on the real line. I will show simulations illustrating these results on the real line.
