Chow, C.-Y.; Olorunsola, O.; Huang, M.-K. Intensification of wave energy on the Lee side of a wavy plateau. (English) Zbl 0616.76119 Z. Angew. Math. Mech. 67, 301-308 (1987). A stable 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.
