Coupling terrestrial and marine datasets for coastal hazard assessment and risk reduction in changing environments

 
 
 

Project background

Coastal instability phenomena which cause heavy socio-economic consequences and fatalities have increased significantly in recent years due to global changes, which determine more frequent extreme meteorological events, and progressive urbanisation of coastal areas, especially in developing countries.

This project is based on previous scientific work, such as the 2009-2011 Project "Coastlines at Risk: methods for multi-hazards assessment" of the CERG. For more information, see the project presentation and the main results for 2011). ICoD and CERG also organised a Post-Graduate Training School on Coastal Hazard Assessment and Risk Management in June 2011 in Caen.

The study areas are the Normandy coast (France) and the coasts of the Island of Malta, which show different morphoclimatic and tectonic setting, but which have been and are at present affected by significant changes in sea level since the Last Glacial Maximum, when the sea level was some 120 metres lower than present.

The activities carried out in the framework of this project in 2012-2015 aimed in particular to:

  • Deliver an original contribution and new directives for risk reduction in coastal areas taking into account historical and possible future climate changes based on the outputs of the CERG 2009-11 Project "Coastlines at Risk: methods for multi-hazards assessment".
  • Develop a multidisciplinary methodological approach which is capable to integrate terrestrial and marine datasets. 
  • Understand of landslide kinematics through generation of knowledge of their submarine spatial and temporal development. This knowledge would of course enable to provide a more comprehensive picture of landslide hazard conditions.

Most significant achievements

Euro-Mediterranean Centre on Insular Coastal Dynamics - Malta :
  • Integration of terrestrial and marine data sets

  • Organisation of a workshop to identify a procedure for the development of hazard maps, integrating sea level rise and the anthropic impacts for both rocky coast environments and sandy beaches

  • Coastal monitoring in Gozo, Anchor Bay and Il-Qarraba (Malta)

  • Survey and monitoring of rocky coastal erosion using Laser techniques (Dieppe coastal cliffs, Normandy)

  • Study adressing the advantages of individual methodologies for coastal risk management (Topographic Aerial Laser Scanning ALS, Terrestrial Laser Scanning TLS and Mobile Laser Scanning MLS)
