OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.

Currently, coastal flooding in the UK costs £320m annually: this is 24% of the total Expected Annual Damage due to all sources of flooding. Scenario analyses of future coastal flood risk are hindered by a useful but over-simple assumption: that of non-evolving coastal morphology (aka ‘bathtub analysis’). To move forward, we urgently need a new generation of simulation models. These must be able to capture the dynamic behaviour of UK coastlines: in particular, coastal responses to human interventions such as removal of hard defences, mega beach nourishments, etc.
Drawing on insights from a wide range of modelling and model integration approaches, Andres Payo and David Favis-Mortlock argue that it is time to rethink the way we conceptualize the evolving coastal landscape, and present a new framework for representing dynamic coastline behaviour: CoastalME (Coastal Modelling Environment).
About the speakers
Andres Payo leads the research on coastal resilience and geohazards at the British Geological Survey. He is a former member of staff of the Environmental Change Institute at Oxford University and is the principal driving force behind CoastalME. David Favis-Mortlock, is an Honorary Research Associate at Oxford University’s Environmental Change Institute, with a background in geomorphological modelling, particularly self-organisation of complex systems.
