Seminar summary:

Martinique’s coastline is today subject to the challenges of environmental forcings that impact its stability and attractiveness. This paper will present the results of two studies that attempt to clarify the processes involved and the associated morpho-sedimentary dynamics for sandy beaches driven by :

  • weather-sea forcing with seasonal cyclicity imposing cross-shore sediment transfers ;
  • massive sargassum seaweed strandings modifying the interplay of actions and feedbacks between beach and swell.

A detailed understanding of these processes is necessary for better forward-looking management of these fragile beaches, which represent a major tourist and economic challenge in this unstable context of climate change.
