We investigate the dynamical behaviour of a coupled dispersionlees system (CDS) by solving its initial-value problem following a dynamical system approach.As a result,we unearth a typical miscellaneous travelling waves including the localized and periodic ones.We also investigate the energy density of such waves and find that under some boundary conditions,the localized waves moving towards positive direction are more stable than the periodic waves which on contrary stand for the most stable travelling waves in another situation of boundary conditions.
