ABSTRACT
Comparatively little work has been reported relating to scour around dynamic structures, and most of this is to do with the structural dynamics rather than to the fluid-soil interaction. For instance, the effect of scour and backfilling on the natural frequency of the structural vibrations has been investigated by Damgaard et al. (2013) who developed a relationship connecting scour depth and backfilling height with Eigen frequency. The research reported here is part of a study focusing on the scour process taking into account the effects of vibration under a variety of hydrodynamic conditions and different bed materials. The aim of this study is to obtain a better understanding of scour development under these conditions to inform the design of offshore structures such as wind turbine foundations in the future.
