The interaction of a flow with topography can generate large-amplitude, horizontally propagating solitary waves.Often these waves appear as a wave-train, or undular bore.In this talk we focus on the situation when the flow is critical, that is, the flow speed is close to that of a linear long wave mode, and the obstacle consists of a single step, either up or down.In the weakly nonlinear regime, this is modeled by the forced Korteweg de Vries equation [1,2], or the extended forced Korteweg-de Vries equation when a cubic nonlinear term is added.
