This paper deals with the monotonicity of limit wave speed c0(h) to a perturbed g KdV equation. We show the decrease of c0(h) by combining the analytic method and the numerical technique. Our results solve a special case of the open question presented by Yan et al., and the method potentially provides a way to study the monotonicity of c0(h) for general m ∈ N+.
