    "abstract": "A parabolic equation for the propagation of periodic internal waves over\nvarying bottom topography is derived using the multiple-scale perturbation\nmethod. Some computational aspects of the numerical implementation are\ndiscussed. The results of numerical experiments on propagation of an incident\nplane wave over a circular-type shoal are presented in comparison with the\nanalytical result, based on Born approximation.",
