Description

Les crues de juin 2024 ont provoqué des dégâts considérables sur l’ensemble du traçé de la Navisence. Sur le secteur du pont de Tarampon la pente du profil en long diminue et le charriage a créé des dépôts importants qui ont obstrué la section du pont (jusqu’à 5 m). Le fond atteignait le niveau du pont et le parapet aval a joué un rôle de déflecteur. Les écoulements se sont dirigés vers la rive droite et ont menacé la rouge de la STEP et totalement détruits le remblai de la route d’accès à la ferme.   Avec la mise en œuvre des mesures prévues en amont de Vissoie, le charriage de matériaux diminuera et la situation sera plus favorable. Toutefois, le secteur du pont de Tarampon conservera une pente inférieure à la pente des tronçons à l’amont. Des apports solides liés à l’érosion des versants continueront, pendant un certain temps, de provoquer des dépôts au droit du pont.  En bref, le principe de l’aménagement de Tarampon consiste donc à : ▪ créer un entonnement tel que prévu par le projet MEP. ▪ surélever la berge en rive droite en amont du pont. La surélévation privilégie l’écoulement par un couloir d’évacuation qui comprend la largeur du pont ainsi qu’une largeur supplémentaire de 10 m à droite du pont. Avec cette configuration on évite la déviation des écoulements vers la route de la STEP. ▪ rétablissement d’un remblai et d’un accès en rive droite ▪ renforcer et végétaliser le talus de la route d’accès et de la STEP.
