Abstract

fetched live from OpenAlex

Depuis le milieu des années 1990, à l’échelle internationale, de nouveaux principes de gestion écologique des cours d’eau sont mis en place. Afin d’améliorer la qualité de l’eau et des milieux aquatiques, il ne s’agit plus uniquement de réduire les flux de pollution, mais d’agir sur la structure même des milieux fluviaux pour rétablir les processus physiques qui orientent la dynamique fluviale. Parmi les actions de restauration écologique les plus emblématiques, l’effacement de barrages et de seuil est une solution de plus en plus mise en avant par les associations environnementalistes, mais aussi par les acteurs institutionnels. La suppression d’ouvrage hydraulique est associée à une « libération » physique et symbolique des cours d’eau. La promotion du démantèlement de barrage semble s’accompagner d’une quête d’un modèle de rivière qui serait plus sauvage. Cet article propose un décryptage du mouvement international de démantèlement de barrage à partir de l’analyse comparée de sa mise en œuvre et de ses implications sociospatiales, entre Amérique du Nord (foyer émetteur) et l’Europe.

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.
