Present morphodynamics models used by coastal engineers suffer from a lack of detail and accuracy when it comes to sand transport in the near-shore region, where waves break and run up and down the beach. The complex interactions between hydrodynamics and sediment transport processes under such non-uniform wave conditions, and effects of additional breaking-generated turbulence, are not well understood – and consequently, not properly accounted for in sand transport formulations.
My research focuses on the complex hydrodynamic and sediment transport processes, in order to assess and improve engineering-type sand transport formulations. I try to achieve this through controlled laboratory wave flume experiments that allow very detailed investigations of the physical processes driving sediment transport.
My PhD research focused on sand transport processes in the surf and swash zones, using experimental data obtained in the CIEM wave flume in Barcelona. This research was done in close collaboration with experimentalists and numerical modellers at the Universities of Aberdeen, Liverpool, Twente and at Deltares within the the joint UK/Dutch research project SINBAD (funded by STW and EPSRC). Specific processes I examined include the effects of wave breaking on wave bottom boundary layer hydrodynamics and the instantaneous response of the bed level and bedload layer to energetic forcing in the swash zone.
At present I am employed as a postdoctoral researcher within the EU-funded HydraLab+ infrastructure. Within this project I am involved in experimental work focusing on hydrodynamics under breaking waves and on graded sediment transport under non-breaking waves.
