Flying just over the caissons belt

The drone takes you just above the caissons belt. A good way to understand how they work : ballasted on the rear part with rocks and sand,  they weigh approximately 20 000 tonnes. It’s a real barrier which brings stability to the land behind. This ballasting work is in progress. On the front part, you can see « Jarlan Chambers ». In the event of a conventional swell or a storm, the waves will rush through these openings and dissipate their energy in two successive chambers.
