Coastal Seminar Series:
2012/2013 Term 3 (Semester 2)
These seminars illustrate the breadth of coastal studies at the University of Southampton. Traditionally, this seminar series is held at Highfield, hosted by the faculty of Engineering and the Environment. This term only, the seminars will be held at NOCS, and will aim to showcase areas of research within the coastal research theme at Ocean and Earth Science.
The seminars will be held on Tuesdays starting at 4pm, in NOCS conference room, 344/32. These seminars are intended for both students and staff, and recent graduates. If you have any queries, please contact Hachem Kassem at Hachem.email@example.com, (x26205).
Tuesday 4th June, 4pm, NOCS conference room, 344/32
Dr Ivan Haigh, Lecturer in Coastal Oceanography, OES
Trends and variability in mean and extreme sea levels around Australia
The incidence of major storm surges in the last decade has dramatically emphasized the destructive capabilities of extreme events, particularly when driven by severe tropical cyclones. In this seminar Ivan will describe the main findings from recent studies he has been involved in, aimed at assessing past and future changes in extreme water level events and estimating present day extreme water level exceedence probabilities around the whole coastline of Australia.
Tuesday 11th June, 4pm, NOCS conference room, 344/32
Prof H.J. Kang, Korean Maritime University
Cross-shore sediment transport due to the nonlinear interaction of waves in the nearshore region
The skewness of near-bottom velocity distribution caused by the nonlinear interaction of the Stokes’ 2nd order waves can explain the on-offshore movement of bottom sediment. In this talk a new concept of neutral depth which can explain the recovery of beach equilibrium after a disturbance is suggested and discussed.
Tuesday 18th June, 4pm, NOCS conference room, 344/32
** Two talks**
- Dr Matthew Wadey, Post-Doctoral Research Fellow, OES
A characterisation of storm surges and extreme water level events around the UK coast
In this seminar Matthew will introduce a multidisciplinary flood research project which aims to understand the temporal clustering of flood events. An initial part of this is to evaluate extreme water level characteristics (e.g. relative importance of tide and surge components, and the spatial footprint of extreme events) using ‘Class A’ tide gauge observations around the UK coast.
- Robert Mawdsley, PhD Candidate OES
Long-term changes in extreme sea level components
In most regions of the world extreme water levels are observed to be increasing at the same rate as mean sea level (MSL). However, significant changes in other components of water level have been observed at individual locations. An accurate understanding of these changes in tide and surge components is essential for the prediction of extreme sea levels. This talk will introduce the changes observed in the three components of water levels and how their contributions vary globally.
Tuesday 25th June, 4pm, NOCS conference room, 344/32
Prof Carl L. Amos, Professor in Sediment Dynamics, OES
Sea surface temperature trends in the coastal ocean
Sea surface temperature (SST) trends in the coastal zone are shown to be increasing at rates that exceed the global trends by up to an order of magnitude. The evidence suggests that urbanization in the coastal hinterland is having a direct effect on SST through increased temperatures of river and lake waters, as well as through heated run-off and thermal effluent discharges from coastal infrastructure.
Tuesday 02nd July, 4pm, NOCS conference room, 344/32
- Dr Charlie Thompson, Teaching and Research Fellow, OES
The Barrier Dynamics Experiments (BARDEX)
This talk will present an overview of the aims and some key findings of the Barrier Dynamics Experiments, a set of prototype scale flume experiments investigating the dynamics and sediment transport processes of gravel and sandy barrier beaches.
- Hachem Kassem, PhD Candidate OES/EE/SMMI
BARDEX II: Nearshore sediment resuspension and bed morphology
This talk will present preliminary results from the 5th workpackage of the BARDEX II experiment on a prototype-scale Sandy Barrier Beach. The implications of intermittent turbulent bursting phenomena on nearshore sediment resuspension under shoaling waves are examined; including statistical, quadrant, and spectral analysis of bed generated turbulence, and vortex shedding from bedforms.
Tuesday 09th July, 4pm, NOCS conference room, 344/32
- Dr Shari Gallop, Teaching and Research Fellow, OES
Video Observations of Rip Currents on an Embayed Beach
Globally, rip currents are one of the main causes of drowning. It is a challenge to devise automated methods to locate rip channels from video imagery, to develop real-time forecasting, and long-term data-sets to increase understanding of their behaviour. This presentation will discuss previous work on rip channel detection, the difficulties and possible ways forward.
- Amelia Astley, PhD Candidate OES/ SMMI
The Taphonomy of historic shipwreck sites
Over time due to environmental pressures (physical, biological and chemical) the structural integrity of a shipwreck declines and the spatial coherency of the shipwreck site becomes degraded. If we wish to better understand the surviving archaeological record we require improved knowledge of the impact of variable marine conditions on wreck sites.
