We will show that the decay rate for the damped one-directional model equations, such as the KdV and BBM equations, holds for some of the damped Boussinesq systems which model two-directional waves.Analysis of PDEs35Q35, 35Q53, 76B15Long-Time Asymptotic Behavior of Dissipative Boussinesq Systemtext
