Description du projet
Le comportement des dunes côtières dans des conditions météorologiques extrêmes
Le changement climatique affecte notre planète de nombreuses façons. Les phénomènes météorologiques extrêmes ainsi que l’élévation du niveau de la mer sont parmi les conséquences les plus graves. Les dunes côtières du versant européen de l’Atlantique sont apparus comme la première ligne de protection naturelle contre les inondations et l’érosion du littoral. Pour mettre au point des outils permettant une gestion des côtes efficace à court et à long terme, il est nécessaire de comprendre et de prévoir le comportement des dunes côtières par rapport aux tempêtes extrêmes et à l’élévation du niveau de la mer. Le projet ERoDES, financé par l’UE, effectuera des observations sur le terrain afin d’anticiper le comportement des dunes côtières dans des conditions météorologiques extrêmes et une élévation extrême du niveau de la mer. Ces observations seront menées en parallèle de l’utilisation d’un modèle basé sur les processus et d’un modèle à complexité réduite, en utilisant des ensembles de données provenant de différentes méthodes d’enquête (télédétection par satellite, LiDAR aéroporté, RTK-GPS, etc.).
Objectif
The ERoDES research project aims, for the first-time, to develop our ability to understand, anticipate, and make projections on how coastal dunes would respond to future extreme storms and sea level rise along the Atlantic coast of Europe. As climate change is expected to cause more intense extreme weather events and an increase in extreme sea levels along the coastline of Europe and other continents, it is crucial to understand coastal dunes behaviour, since they serve as the first line of protection against coastal erosion and flooding. Field observations, a process-based and a reduced-complexity model will be used to hindcast and forecast dune behaviour at highly diverse coastal environments under previous and future sea level rise and extreme storms scenarios. These results will provide useful information and tools for short-and long-term coastal management strategies along the Atlantic coast of Europe. The researcher has demonstrated over the last few years a strong knowledge and understanding of geomorphological and hydrodynamic processes along diverse coastal environments, and aims to develop his numerical modelling skills through this project, benefiting from the strong experience of the supervisor. Knowledge exchange between the researcher and the host will offer the opportunity to explore niche topic such as the use of Satellite data, and to analyse outstanding but yet unexploited LiDAR datasets. The various achievements of this multidisciplinary project will be disseminated to both academic and non-academic key actors of coastal science and coastal management, adding social and economic repercussions to the scientific impact of the ERoDES project. Communication activities such as a scientific field trip, a science festival, and the presentation of new technologies used in coastal science like drones, will also be organised with the wider public to illustrate how EU-funded research aims to contribute in reducing risk in coastal flooding and erosion.
