Coastal protection structures

Physical modelling to define strategies for adapting coastal protection structures.

What we do

Studies of coastline management methods
Rehabilitation or adaptation of existing protection structures
Studies of the impact of developments on coastal morphodynamics and coastline changes
Assessment of flood risks
Definition of mitigating measures to accompany the implementation of development works.

Modelling using a wave flume (2D) or wave tank (3D) to study the stability of protection structures: groynes, breakwaters, backshore protection
Measurement of the forces and pressures exerted by breaking waves on structure facings, crest walls and backshore revetments
Measurement of overtopping of structures and risks of flooding behind the coastal strip.
Implementation of movable-bed sedimentological modelling to:
- examine long-term or seasonal changes to the coastline
- study changes to the bed profile during storm periods, erosion risks at the toe of structures, and scour protection systems
- analyse the impact of developments on longshore drift and effects on coastal morphodynamics (quantify risks and volumes of sedimentation and/or erosion, estimate coastline retreat)
- investigate and develop management methods combining effective protection with limited impact on the ecosystem: beach nourishment, dune strengthening, bypass systems, development works, relocation of elements at risk further inland.
