Why the littorals?One of the most direct consequences of climate change will be the littoral crisis due to flood risks (www.eurosion.org). Once we realise that these changes will effectively happen, it is necessary to launch long-term Civil Defence policies in order to protect the places where the CC effects overlap other concomitant phenomena, since it is there that CC will cause the worst damage. Coastal zones are already hit by erosion, river floods and subsidence, but nonetheless they are more and more urbanised and crowded. Therefore, we need to promptly study the most suitable solutions in order to prevent risks from worsening. This is especially true for these littorals, which are more exposed to flood risks due to their particular morphology: coastal ponds bounded by dune belts or areas below sea level, river deltas, polders, etc.
