Abstract

fetched live from OpenAlex

Alluvial rivers undergo lateral channel change through progressive lateral migration at bends or through channel avulsions. The floodplains of rivers experiencing lateral channel change contain geomorphic features indicative of past migration. Based on aerial photography spanning from the late 1940s early 1950s to the 1970s 1980s, insignificant lateral channel change occurred along the lowest reaches of the Root, Willowlake, Blackwater, Great Bear, Hume, Ramparts, Hare Indian, Ontaratue, and Arctic Red rivers; all of which have a meandering or meandering-straight planform. In contrast, the lowest reaches of the North Nahanni, Dahadinni, Redstone, Keele, Mountain and Carcajou rivers have all experienced significant lateral channel change, ranging from up to 3 m/year to 11 m/year. An increase in the magnitude and frequency of extreme flows arising from climate warming may cause an overall increase in the rate of bank erosion and net widening of the channel along those river reaches presently experiencing active lateral migration.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
