Abstract

fetched live from OpenAlex

Levées, duits et chevrettes imprègnent fortement les paysages fluviaux de la vallée de la Loire, par leur omniprésence et leur intégration aux structures des villes ligériennes, anciennes cités portuaires. Ces ouvrages opérationnels au temps de la navigation ligérienne et aujourd’hui révolus perturbent toujours la dynamique fluviale : influence des conditions d’écoulements, impacts sur la dynamique sédimentaire, végétalisation du lit entre levées. Ces objets fluviaux ont contribué au réajustement fluvial toujours en cours. L'approche géohistorique du XIXe au XXIe siècle montre que le paysage fluvial du lit entre levées s’est profondément modifié en réponse à l’arrêt brutal de la navigation et des modes d’entretien des chenaux à la fin du XIXe siècle. Pour illustrer l’impact de ces friches hydrauliques sur le paysage fluvial, nous nous intéressons aux digues submersibles de deux sites de la Loire moyenne : La Charité-sur-Loire et sa chevrette, Orléans et ses duits. Des conflits naissent et des enjeux apparaissent à l’issue de cette trajectoire paysagère : entretenir et restaurer le lit fluvial, maintenir ou supprimer des aménagements fluviaux, valoriser le patrimoine de navigation.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
