The mean solutions for the Kuramoto-Sivashinsky (KS) equation with incoming boundary were discussed. The KS equation had two different spatial scales which correspond to chaotic motion and the representative change of mean values. It was observed that the model equation does not includes any empirical parameters. It was found that the adequacy of the model equation was verified by comparing solutions of the model equation with time-averaged solutions obtained from t he numerical simulation of the KS equations.
