Abstract
It turns out that evolution of localized finite-amplitude disturbances in p erturbed KdV equation is qualitatively different compared with conventional small-amplitude initial conditions. Namely, relatively fast solitary waves , with one and the same amplitude and velocity, are formed ahead of convent ional chaotic-like irregular structures. The amplitude and velocity of the waves, obtained from the asymptotic theory, are in excellent agreement with numerics.
