Les journ\u00e9es annuelles DYNALIT se sont tenues les mardi 11 et mercredi 12 juin derniers, organis\u00e9es par le Geo - Ocean Laboratory<\/span><\/a> de l\u2019University of Southern Brittany<\/a><\/span> de Vannes.<\/span><\/p>\n

Qu'est-ce que DYNALIT ? DYNALIT<\/a><\/span> est un Service National d'Observation labellis\u00e9 par le CNRS INSU (Institut National des Sciences de l\u2019Univers), d\u00e9di\u00e9 \u00e0 l'\u00e9tude de la dynamique du littoral et du trait de c\u00f4te. Ce service implique plus de 120 personnes, parmi lesquelles des chercheurs, des enseignants-chercheurs, des doctorants et des ing\u00e9nieurs. DYNALIT se charge de l\u2019acquisition, de la collecte et de la mise en coh\u00e9rence de donn\u00e9es m\u00e9trologiques de qualit\u00e9 sur une trentaine de sites ateliers (c\u00f4tes sableuses, falaises, embouchures) r\u00e9partis le long de toutes les fa\u00e7ades maritimes fran\u00e7aises.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div>

Les journ\u00e9es annuelles ont pour objectif de r\u00e9unir les responsables des diff\u00e9rents sites afin de pr\u00e9senter l\u2019\u00e9tat des suivis, les \u00e9tudes men\u00e9es et leurs r\u00e9sultats.<\/span><\/p>\n

La premi\u00e8re journ\u00e9e \u00e9tait consacr\u00e9e \u00e0 l\u2019assembl\u00e9e g\u00e9n\u00e9rale du r\u00e9seau et aux pr\u00e9sentations des diff\u00e9rents travaux men\u00e9s sur les sites repr\u00e9sent\u00e9s. \u00c0 cette occasion, trois nouveaux sites ont \u00e9t\u00e9 int\u00e9gr\u00e9s et pr\u00e9sent\u00e9s aux membres du r\u00e9seau DYNALIT (la plage des Chevrets, la falaise de Porzh Koubou-Tromel et la plage de La Palue et Lostmarc'h').<\/span><\/p>\n

La deuxi\u00e8me journ\u00e9e \u00e9tait d\u00e9di\u00e9e \u00e0 la d\u00e9couverte des deux sites DYNALIT du Morbihan. Elle a d\u00e9but\u00e9 \u00e0 P\u00e9nestin, au pied de la Falaise de la Mine d\u2019Or, site embl\u00e9matique du d\u00e9partement. La g\u00e9ologie, les mouvements, l\u2019histoire et l\u2019\u00e9volution de ce site ont \u00e9t\u00e9 pr\u00e9sent\u00e9s aux participants lors d\u2019une balade guid\u00e9e par David MENIER, responsable du site au sein du r\u00e9seau.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

Le groupe a ensuite pris la direction de la commune de Sarzeau pour d\u00e9couvrir la plage de Suscinio et son ch\u00e2teau. Mouncef SEDRATI, responsable de ce site, a guid\u00e9 les participants en pr\u00e9sentant la dynamique de cette plage longue de 5 kilom\u00e8tres et ses sp\u00e9cificit\u00e9s.<\/span><\/p>\n

Le dernier arr\u00eat de la journ\u00e9e a eu lieu \u00e0 la pointe de Penvins (pointe Est de la plage de Suscinio), o\u00f9 plusieurs dispositifs d\u00e9velopp\u00e9s par le laboratoire Geo-Ocean sont install\u00e9s. Le premier dispositif est une borne CoastSnap, r\u00e9cemment install\u00e9e en partenariat avec Golfe du Morbihan Vannes Agglom\u00e9ration. Cette borne permet de suivre l\u2019\u00e9volution du trait de c\u00f4te et les mouvements s\u00e9dimentaires aux abords de la digue de Penvins gr\u00e2ce \u00e0 la participation du public. Le second dispositif comprend une s\u00e9rie d\u2019AlgoBox<\/a><\/span>\u00ae, install\u00e9es au pied de la dune. Ce syst\u00e8me de casiers de ganivelles, utilisant des solutions fond\u00e9es sur la nature, r\u00e9g\u00e9n\u00e8re la dune en pi\u00e9geant le sable transport\u00e9 par le vent. Les casiers sont ensuite remplis d\u2019algues provenant des \u00e9chouages massifs locaux, servant de protection et de compost pour acc\u00e9l\u00e9rer le d\u00e9veloppement de la v\u00e9g\u00e9tation dunaire.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div>
