Why this work?
Faced with coastal dynamics and the effects of climate change, preserving our coastline has become a major challenge. For several years now, Perpignan Méditerranée Métropole (PMM) has been taking steps to preserve its coastline: restoration of the dune cordon, creation/rehabilitation of breakwaters, recharging, observation, etc.
Perpignan Méditerranée Métropole Communauté Urbaine, which has been responsible for "combating coastal erosion and marine submersion" since 2010, has launched a dune restoration program on the Sardinal beach in Canet-en-Roussillon.
What facilities are planned?
The current work involves surface purging of concrete blocks and exposed reinforcement at the foot of the dune, renewal of damaged wooden ganivelles and rails, and the addition of new lines in areas where there is a lack of vegetation and/or insufficient dune height. Lastly, suitable vegetation will be planted in the two Sardinal sectors.
This "flexible" management method is the only operational technical solution deemed compatible by the 2018 "Stratégie Régionale de Gestion Intégrée du Trait de Côte" for the Sardinal - crouste sud sector in Canet. The aim is to delay the morphological degradation of this sector, which is subject to strong erosion dynamics due to the presence of the harbor dike.
