Project: Coastal adaptation under sea level rise using soft engineering (dynamic revetment)

Supervisors: Dr Christopher Blenkinsopp, Dr Alan Hunter and Prof Gerd Masselink

Global mean sea level is rising at an increasing rate, and this represents one of the main long term coastal hazards. Existing hard engineering coastal defences are neither designed nor efficient against Sea Level Rise (SLR), and therefore are likely to be over-topped 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 behaviour and the capacity of the revetment to adapt and protect sandy beaches against waves attack and 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 and numerical modelling to better understand beach profile evolution under SLR. He is also interested in general coastal protection with a specific expertise in submerged artificial reef and dynamic revetment. He is also trained in operational oceanography and survey management.

Before joining the WISE 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. Paul also led and managed a Hydralab+ project, running the DynaRev experiment at the GWK large scale flume.
