In this paper we discuss the structural stability of an initial value problem defined for the equation u(t)-u(txx) + auu(x) = beta u(x)u(xx) + uu(xxx) (i. 1) where alpha,beta are constants, x is an element of R, is an element of R+. For the choices of alpha and beta , (i. 1) describe the nonlinear shallow water waves. Upper and lower bounds are derived for energy decay rate in every finite interval [0, T] which reveals that only the lower bound of the energy decays exponentially.
