Abstract A stably stratified channel flow over a wavy plateau is analyzed to examine the effect of topographic wavelength on wave energy in the flow downstream. A resonance phenomenon is found to occur at wavelengths that are determined by the Richardson number and channel geometry. Results show that in a resonant state, the unbounded wave drag of the plateau is caused by the sinusoidal pressure distribution when it becomes out of phase with the topographic deformation.
