Hachem Kassem is a Teaching & Research Fellow in Coastal Morphodynamics & GIS in Ocean and Earth Science at the University of Southampton. His current research focuses on physical processes governing sediment dynamics in the coastal zone. He is member of the Geology & Geophysics research group (coastal research theme). 

Hachem's research is focussed on understanding physical processes governing sediment transport in the coastal zone, with emphasis on turbulence and loose boundary hydraulics, coastal erosion and flooding, and interactions between waves, currents, sediment, vegetation and structures; employing prototype-scale experimental data, fieldwork measurements and complex numerical tools. He has worked on collaborative projects with industry, local government and academia; studying nearshore sediment entrainment and barrier beach dynamics, exchanges between coastal lagoons and open seas, turbulence and sediment dynamics in wave-current flows, flooding and barrier erosion in bi-modal seas, flow and sediment dynamics in seagrass and mangrove fields, and scour around marine structures. He currently coordinates a large project studying shoreface dynamics in a mixed/composite gravel-sand barrier beach in the UK.

Academically, Hachem is primarily involved with the MSc Engineering in the Coastal Environment (ECE) course, coordinating MSc level modules in coastal sediment dynamics and applied coastal oceanography, as well as the practical component (physical modelling, lab work and field campaigns) of a module on modelling coastal processes. He supervises several MSc research projects, and contributes to the general administration of this masters programme.. Hachem also contributes to a 2nd year undergraduate module in GIS & Remote Sensing for Geology/Geophysics students and general outreach and curriculum development in the school.  

Hachem’s background is in Civil Engineering, with focus on engineering and environmental hydraulics. He completed a PhD in 2016 studying coherent turbulence structures and sediment resuspension in the coastal benthic boundary layer, focussing on wave-dominated flows in the nearshore, and on combined wave current interactions. 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. He has also been involved in a number of research projects, including the EU-funded Hydralab IV Barrier Dynamics Experiment II; and the Italian Ritmare framework for marine research.

Hachem also directs the coastal labs (sediment analysis lab, coastal processes lab and sediment dynamics lab) in Ocean and Earth Science.

Research interests

Hachem's main research interests focus on understanding the fundamental physical processes that govern the transport of sediment in coastal environments, with emphasis on small-scale turbulence processes in wave dominated environments and under combined wave-current flows. He employs proto-type scale experiments and field measurements, coupled with complex numerical processing and computational modelling to study coherent turbulent motions and fluid-sediment-bedform interactions with/without vegetation and structures.

Hachem is also interested in the morphodynamics of wave-dominated coastlines at engineering time scales, with a view to inform process-based modelling as well as practical engineering interventions designed to tackle coastal erosion and flooding.

Hachem is also involved in monitoring and modelling coastal processes, including  a study into the hydrodynamic controls of mega-scour at a triple Junction (Torcello, Venice lagoon), exchanges between a coastal Lagoon and the open sea (Cabras, Sardinia), bedload transport in a tidal inlet (Lido, Venice Lagoon), field measurement of physical and hydrodynamic roughness (Cabras Lagoon). He is currently involved in a study of the shoreface dynamics of a mixed/composite gravel/sand barrier beach in Pevensey Bay, UK and in the development of novel scour control /protection for offshore monopile structures.
