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

‚ÄėSkinny‚Äô landslides and big earthquakes

Earthquakes and associated tsunamis can be exceptionally dangerous. In the last 12 years, earthquakes and tsunamis offshore Sumatra, Japan and Haiti have killed over 350,000 people. Despite this, many large and growing population centres are located close to plate boundaries worldwide, which is where most large earthquakes occur. It is therefore important to understand how… Read More ‚ÄėSkinny‚Äô landslides and big earthquakes

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’

Fieldwork mapping sea-grasses and sediment sampling for grain trend analysis at Ryde, IoW

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‚Äôs… Read More Fieldwork mapping sea-grasses and sediment sampling for grain trend analysis at Ryde, IoW

Sun, sea and scour: The International Conference on Scour and Erosion ‚Äď 7, Perth ‚Äď by Amelia Astley

G&G postgraduate research student Amelia Astley reports on her recent trip to Perth, to present at the ICSE2014 conference:   Held every two years the International Conference on¬†Scour and Erosion (ICSE) is the mecca for all soil and sediment engineers worldwide. This year the conference was held from the 2nd to the 4th December, at… Read More Sun, sea and scour: The International Conference on Scour and Erosion ‚Äď 7, Perth ‚Äď by Amelia Astley

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
