Processes involued in the morphodynamics evolution of Roberts Bank (Fraser Delta) (hydrodynamic and sedimentary in situ observation and modelling)
Bibliographic record
Abstract
Sous la pression anthropique et la modification du régime sédimentaire, la plage de sable fin de Roberts Bank (Delta du Fraser, Canada) est soumise à une érosion significative. Des périodes de mesures et de modélisation ont permis d identifier les processus hydrodynamiques et sédimentaires associés aux courants de marée et à la houle. A marée montante, les structures sédimentaires, en haut de pente deltaïque, fournissent une rugosité de fond qui favorise la remise en suspension des sédiments. A marée descendante, les sédiments sont transportés vers le large par un panache de surface et par les chenaux. Un processus dit de "mixing-induced convective sedimentation" accélèrent alors le dépôt. L'incidence des vagues de tempêtes, la morphologie et le marnage vont influer sur une divergence du transport sédimentaire. Celui-ci est à la côte à marée haute, et vers le large à marée basse. La surcote de tempête participe avec les courants de jusant et d'arrachement à un transport vers le large.

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.
