Coastal Changes and Cultural Heritage (1) : Assessment of the Vulnerability of the Coastal Heritage in Western France

International audiencePresent climatic change and anthropogenic pressure increasingly affect the coastal zone. The Channel and Atlantic seaboards of France are no exception, with hundreds of archaeological sites currently threatened by the accelerated relative rise in sea level, erosion, and various anthropogenic modifications to the environment. In this article we propose a multidisciplinary approach to assess the vulnerability of archaeological heritage in the West of France. We also aim to establish an original methodology (and specific tools) for the observation of risks and the definition of impacts they may have on heritage sites. This research opens up a theoretical perspective for building a vulnerability model for archaeological heritage that takes into account the evolution of the environment and the specificity of each site over the course of the next 20 to 30 years
