Coastal protection and near-shore evolution under Sea Level Rise - Paul Bayle
Supervised by Dr Chris Blenkinsopp, Dr Alan Hunter, Professor Gerd Masselink
Global mean sea level is rising at increasing rate, and this represents one of the main long term coastal hazard. Existing hard engineering coastal defences are neither designed nor efficient against Sea Level Rise (SLR), and therefore are likely to be overtopped and breached during this century.
A recent soft engineering technique named “dynamic revetment” or “cobble berm” has been implemented in some coastal places to protect the hinterland against storm wave and erosion. This type of revetment is not static and moves under wave’s action while dissipating the wave’s energy. By optimising the design of the dynamic revetment as well as the deployment area, this structure is supposed to self-maintain its relative position to sea level under SLR. The pebbles composing such a protection are expected to move landward under SLR, thus keep protecting the hinterland against future extreme wave climate.
The performance of the revetment was tested in the GWK large scale flume, Hannover, Germany, through the ‘DynaRev’ experiment. The experiment was designed to assess the behavior and the capacity of the revetment to adapt and protect sandy beach against waves attack and SLR. The experiment was also designed to provide a large range of morphodynamic data required for a better understanding of general coastal processes under SLR.
Paul is a PhD student based at the department of Architecture and Civil Engineering at the University of Bath. He is part of the Water, Environment and Infrastructure Resilience (WEIR) research group, and the Water Innovation and Research Centre (WIRC). Paul’s research is focused on physical, numerical and computational modelling to better understand beach profile evolution under sea level rise. He is also interested in general coastal protection with a specific expertise in submerged artificial reef. He is also trained in operational oceanography and survey management.
Before joining the Water Informatics and Science of Engineering (WISE) Centre for Doctoral Training (CDT), Paul completed a two-year degree in Civil Engineering at the University of Paul Sabatier in Toulouse, then a BSc degree in Earth and Environment Science at the University of Bordeaux and an MSc degree in Oceanography at the University of Southampton. His MSc thesis was completed at the Griffith Centre for Coastal Management (Australia) on beach morphodynamics impacted by artificial submerged reef, under the supervision of Rodger Tomlinson and Darrell Strauss. Paul also led and managed a Hydralab+ project, running the DynaRev experiment at the GWK large scale flume.
