Kurzfassung:
It is shown that the standard stair-step representation of a sloping bottom may result in significant prediction errors. In fact, current parabolic equation implementations are not energy conserving. The problem is shown to derive from the approximate treatment of the interface conditions at vertical boundaries along the stair steps. Several improved interface conditions are proposed.
