Absence of localisation in ocean wave interactions with a rough seabed in intermediate water depth

Abstract

The possibility of a rough seabed causing localisation of ocean waves in intermediate water depth is considered. A numerical and analytical study of the localisation phenomenon is conducted using a transect model and linear potential theory. It is shown that although the effective wave field is strongly attenuated by the roughness, leading to previous predictions of localisation, individual wave fields are not localised.
