Abstract

fetched live from OpenAlex

The segmenting of gravel-bed rivers into 'sedimentary links', characterized by single-sediment sources and downstream fining of alluvial sediments, is a relatively new technique which has had limited application. The sedimentary link concept has been primarily applied to alpine river environments where link formations are supplied by coarse sediment from active point sources. The purpose of this study is to apply the sedimentary link concept on the Ste Marguerite River in the Saguenay region of the Canadian Shield, where valley-segment deposits of coarse sediment from ancient glacial processes are dominant in forming links. Specifically, this study examines link-scale trends in surface grain size and channel slope. This study also uses the sedimentary link concept within an ecological context to explain the spatial organization and quality of Atlantic salmon spawning and rearing habitat.

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.
