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
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
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
This article was published in The Conversation by Ivan Haigh (Physical Oceanography) and Shari Gallop (Geology and Geophysics) from Ocean and Earth Science, University of Southampton. Coastal floods are a major global hazard. In 2008, Cyclone Nargis generated a five-metre storm surge along the coast of southern Myanmar. This swept seawater 50km inland, killing a… Read More SurgeWatch: New database on coastal flooding in the UK
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 – 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’
Earlier this month, 7 Southampton researchers travelled to the Young Coastal Scientist & Engineer’s conference (YCSEC), in Manchester. Post-doctoral researcher, Matt Wadey, along with PhD students Seb Pitman, Rob Mawdsley, Aimin Amiruddin, Clementine Chirol, Esme Flegg and Anas Mohamad Annuar all made the journey for the conference. The conference is aimed at young scientists and… Read More Strong Southampton presence at 11th Young Coastal Scientists and Engineers Conference
Ryde, Isle of Wight boasts one of the largest seagrass meadows in the United Kingdom’s southern region. In order to understand the influence of the seagrass meadow on sediment transport and intertidal flats stability, a two-day fieldwork (18th – 19th March 2015) was conducted. The fieldwork is part of a G&G postgraduate student, Anas Annuar’s… Read More Fieldwork mapping sea-grasses and sediment sampling for grain trend analysis at Ryde, IoW
Clementine Chirol, first year PhD student in Geology and Geophysics reports on her latest field campaign (19th and 23rd February, 2015): Managed Realignment (MR), the process of deliberately removing flood defences to restore intertidal habitats, is undertaken to compensate for coastal developments such as ports, but also as a mean of improving flood defences. Such… Read More Fieldwork at the Steart managed realignment scheme, Somerset
Shari Gallop, Sebastian Pitman and Ivan Haigh from Ocean and Earth Science, University of Southampton are collaborating with Dr Karin Bryan from the University of Waikato and Roshanka Ranasinghe (UNESCO-IHE, Deltares, ANU), to understand the dynamics of rip currents. Rip currents are jet-like flows in the surf zone. Globally, rips are one of the main causes of… Read More Ripping it up in the Antipodes
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
