New understanding of rip currents could help to save lives

This is a press-release for a new paper –¬†Wave breaking patterns control rip current flow regimes and surf zone retention, published by members of the coastal group which can be accessed¬†here. Research by the Universities of Southampton and Plymouth has found a new link between breaking waves and the hazard posed by rip currents. The… Read More New understanding of rip currents could help to save lives

Wave-induced coherent turbulence structures and sediment resuspension in the nearshore

Hachem Kassem, and co-authors Charlie Thompson, Carl Amos, and Ian Townend from¬†the¬†Geology and Geophysics research group have been studying the complex interactions between wave-induced turbulence and sediment resuspension. The results of their study, which used data collected during the Barrier Dynamics Experiment II (BARDEX II);¬†a large EU funded project, part of the Hydralab IV framework… Read More Wave-induced coherent turbulence structures and sediment resuspension in the nearshore

Tomographic investigation of turbulence and sediment dynamics

Understanding sediment transport has come a long way since the pioneering works of Shields and Bagnold, nearly a¬†century ago. Yet, the complex mechanisms that drive, at larger scales, the morphological evolution of coastal and estuarine environments remain poorly understood at the ‘noisy’ end of the spectrum. Fundamentally, this is a problem of fluid sediment interaction,… Read More Tomographic investigation of turbulence and sediment dynamics

Keynote lecture by Prof Carl Amos at ‘Turbulence and Interactions in Marine Systems (TURBINTERMARS): Turbulence and Sedimentary Processes’

An international¬† workshop on turbulence and the resulting sedimentary responses was held in The Abdus Salam International Centre for Theoretical Physics, Trieste, Italy. The meeting spanned three days over 23 ‚Äď 25 February, 2015 and covered topics that ranged from the coastline to the deep sea. There was a good balance between theoretical modelling of… Read More Keynote lecture by Prof Carl Amos at ‘Turbulence and Interactions in Marine Systems (TURBINTERMARS): Turbulence and Sedimentary Processes’

G&G team studying turbulence and sediment dynamics are first to use the Fast Flow Facility at HR Wallingford

Members of the G&G group (coastal processes research theme) have recently had the privilege to be the first external users of the new HR Wallingford¬†Fast Flow Facility (FFF). The FFF is a unique facility that allows studying wave-current-sediment interactions at a large scale. This collaboration came to support the work undertaken by postgraduate researcher Hachem… Read More G&G team studying turbulence and sediment dynamics are first to use the Fast Flow Facility at HR Wallingford

Field campaign investigating the hydrodynamics and sediment dynamics in Venice Lagoon, Italy

A¬†research team from the coastal processes research theme¬†within Geology and Geophysics,¬†led by Prof¬†Carl L. Amos, with¬† PhD student¬†Hachem Kassem, has recently completed a scientific¬†field campaign in Venice Lagoon, Italy.¬†The work was undertaken within¬†RITMARE¬†framework, the¬†Italian National programme of scientific and technological marine research; through sub-project 3, Work Package 4, Action 5; ¬†WP4.A5 on hydrodynamic and morphodynamic… Read More Field campaign investigating the hydrodynamics and sediment dynamics in Venice Lagoon, Italy

Great Barrier Reef is a remarkably efficient wave attenuator

New research has found that the Great Barrier Reef, as a whole, is a remarkably effective wave absorber, despite large gaps between the reefs. This means that landward of the reefs, waves are mostly related to local winds rather than offshore wave conditions. As waves break and reduce in height over reefs, this drives currents… Read More Great Barrier Reef is a remarkably efficient wave attenuator

PhD student Hachem Kassem awarded first prize at Aquatec Equipment Awards

G&G phd student Hachem Kassem has recently accepted an ¬†award for the AQUAscat¬†1000R acoustic suspended profiler;¬†the first prize at the¬†Aquatec Equipment Awards 2014 for his research on¬†vertical turbulence structures in the benthic boundary layer.¬†The award comprises a 3 month instrument loan and a travel grant, to deploy the instrument in an upcoming field campaign. The… Read More PhD student Hachem Kassem awarded first prize at Aquatec Equipment Awards

Southampton team research Cornish rip currents

By PhD student Sebastian Pitman: A team of researchers from both the Geology and Geophysics and Physical Oceanography research groups at the University of Southampton have recently spent two weeks studying rip currents on Perranporth beach in Cornwall. The deployment forms an integral part of G&G PhD student Seb Pitman‚Äôs research, helping to ground truth… Read More Southampton team research Cornish rip currents
