Mr. Chair, I have to say that we aren't infrastructure experts or engineers. We can observe the impacts of climate change or anthropic phenomena on infrastructure, but we can't determine what the best solution would be.
However, going back to the idea that sediments must be allowed to be transported along the shoreline so they can travel, as Ms. Lagarde said, you have to permit exchanges between land and water. Sediments have to be constantly transported along the shoreline; this will help reduce friction along established infrastructure.
I think that's a fairly important element that could be implemented by various means.
