| Abstract | The processes of near bed sediment dynamics involves feedback mechanisms, with the hydrodynamics, bedforms and sediment transport each mutually interacting and modifying one another. To understand these interactions requires co-located, simultaneous, high temporal-spatial resolution measurements of the three components of this interacting sediment triad. To study the triad, acoustics has been increasingly utilised over the past two decades. The development and application of acoustic systems capable of measuring near bed hydrodynamics, suspended sediments, bedload and bedforms is now contributing significantly to the measurement of sediment transport processes. Here we look at the application of these acoustic techniques to the study of sediment transport in large scale wave flume facilities and present results on sediment dynamics over sandy rippled beds under waves. |
