Climate change has impacts on infrastructures and their environment. Ports, being strategic infrastructures, are therefore faced with marine hazards (sea level rise, erosion, floods, storms), in addition to other hazards such as fires or drought episodes.
These hazards must be taken into account in management and maintenance strategies, and ultimately in the strategy of port infrastructure resilience, particularly in the South-West European space.
The ECCLIPSE project aims to identify the impacts of the various hazards on the seaports of this region, in order to determine the elements of an adaptation strategy and to provide the tools for managers to assess and manage risks.
Managers will thus be able to direct investments towards taking into account the resilience of infrastructure to disasters and the development of disaster management systems, in order to ensure the continuity of commercial activity.
ECCLIPSE consists of three main components:
-
Development of a common methodology for the analysis of impacts on ports:
-
Identification of climate risks on port infrastructures and operations,
-
Identification of port infrastructures and operations likely to be affected
-
Definition of the operational limits of the various port operations.
-
-
Selection of large-scale climate change scenarios and study of the impacts on the port environment:
-
Analysis of climate change scenarios that could have the greatest impact on the ports of the SUDOE area
-
Adaptation of scenarios at the local level,
-
Pilot operations in ports to analyse the effects derived from climate models by studying the main climate variables affected
-
Quantification of the impacts of climate change effects on port infrastructures and operations.
-
-
Development of a strategy of adaptation to the effects of climate change in the port system of the SUDOE area.
Cerema will bring in particular its expertise in infrastructure, the impact of climate change on infrastructure, and asset management, as well as in the hydrodynamic modelling of the effects of climate change on the Atlantic coast, on hydro-sedimentary dynamics, the risks of submersion, and the morphodynamic evolution of the Gironde estuary.
The GIRONDE XL 3D tool, which has been developed, facilitates navigation and makes it possible to anticipate the impacts of climate change on dredging.
This work with the Grand Port Maritime de Bordeaux (another partner of the project) on the impacts of climate change on port infrastructures and functionalities, based on a national methodology developed for transport infrastructures and applied for the first time in a port.
