In situ Flume Measurements of Sediment Erodability in Saguenay Fjord (Quebec, Canada)
Bibliographic record
Abstract
The erodability of surficial sediment in Saguenay Fjord, Quebec, was investigated over a three-year period at fourteen sites in Baie des Ha! Ha! and the North Arm using a benthic flume, Miniflume. Previous studies showed that Saguenay Fjord sediment characteristics vary greatly on small and large scales. The critical shear stress (τc) reflect this variability, with τc between 0.07 and 0.48 Pa. The measured critical shear stress and erosion rates were consistent with those of other in situ studies in other areas. The variability in the results is linked to the great spatial variability of benthic sediments rather than to temporal variability. Some of the results were integrated in the Parchure and Mehta (1985) erosion law since the upper portion of the active sediment layer is typically a stratified bed. The identification of erosion parameters (critical shear stress, erosion rate, parameters α and Ef in erosion law) and their high variability is the first step in defining the erosion susceptibility hazard in Saguenay Fjord.

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.
