L’impact d’un couvert de glace sur la dynamique des niveaux et débits dans un estuaire méso tidal
Bibliographic record
Abstract
Cet article présente une modélisation numérique (1-D) à éléments finis de l'estuaire de la rivière Portneuf, Québec (profondeur moyenne de 3m et 5,9km de long).Les marnages de 1,8m (marées mortes) et de 3.0m (marées vives) sont amortis en présence d'un couvert de glace.Proche du barrage (5,6 km de l'embouchure) l'atténuation varie entre 17% et 37% respectivement.Les débits engendrés lors du flot (flux) par les marées mortes et vives sont typiquement 200m 3 /s et 500m 3 /s à l'embouchure.Lorsqu'il y a couvert de glace, ces valeurs sont atténuées de 30m 3 /s à 100m 3 /s respectivement, alors qu'au jusant, l'atténuation est d'environ 50m 3 /s indépendamment du marnage.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
