In this study, acoustic profiling techniques are used to resolve the two-dimensional spatial structures of the oscillating boundary layer in a phase-averaged sense over a wave orbital amplitude. The principal objective of this work is to examine the spatial variability of turbulent properties over irregular roughness. Field observations are used to investigate the interaction between bottom roughness, flow structure and turbulent properties within the near-bed flow. The overall focus of the research is to relate wave energy dissipation or friction factor estimates to physical roughness elements and understand the dynamics of such processes in the near-bed flow.
