TURBULENCE CHARACTERISTICS IN THE BOTTOM WAVE-CURRENT BOUNDARY LAYER

The topic of wave-current interaction (WCI) has received much attention in the past few decades due to its significant applications in sediment transport and marine energy exploitation. For example, prediction of sediment transport rate and coastal morphology, design of harbour structures, pipelines and tidal turbines all require an improved understanding of wave-current interaction. Past studies have identified the non-linear characteristics of WCI, with experimental studies describing the phenomena and analytical models attempting to quantify them. The main objective of this project is to provide new experimental results for the turbulence characteristics in the bottom boundary layer of a combined wave-current flow.
