Event details

Turbulence is the most common yet most complex form of fluid motion, where flow appears to be random and unpredictable at all space and time scales. Understanding turbulence is of huge scientific and technological importance, yet it remains an elusive subject, often described as the last unresolved problem in classical physics. On a beach, or indeed in any other coastal setting, turbulence plays a fundamental role in transporting sediments under the combined action of waves and/or currents. However, the problem here is further complicated by the interactions between the fluid, the particles in transport, and the existing morphology. There is a genuine need for better understanding of these processes to improve our ability to manage coastlines and predict their behaviour in response to changes such as rising sea levels. In this talk, I will take you on a journey through turbulence, drawing on scientific, artistic and literary influences, and describe the work carried out in my phd, studying turbulence and sediment transport on sandy beaches.

Speaker information

Hachem Kassem,is a Teaching Fellow in Coastal Morphodynamics & GIS in Ocean and Earth Science, and a post-graduate research student studying coherent turbulence structures and coastal sediment dynamics at the University of Southampton. Hachem is primarily involved with the MSc Engineering in the Coastal Environment (ECE), coordinating one module and contributing to teaching at postgraduate and undergraduate levels. Having completed the ECE Masters in 2012, he became a post-graduate research (PhD) student in Ocean and Earth Science (based at the National Oceanography Centre, Southampton) and the Faculty of Engineering and the Environment, and Southampton Marine and Maritime Institute. His PhD studies the vertical turbulence structure in the benthic boundary layer in relation to suspended sediment transport. He has worked as a researcher on a number of projects, including the EU-funder Hydralab IV Barrier Dynamics Experiment II; and the Italian Ritmare framework for marine research. Hachem’s background is in Civil Engineering, with focus on engineering and environmental hydraulics. He has worked on the development of Artificial Neural Networks to predict groundwater and river flows, and taught hydraulics and surveying to civil engineering undergraduates.
