Techniques and Measurements for Flows and Water Levels in a Large Northern Delta
Bibliographic record
Abstract
Field work on the Athabasca part of the Peace Athabasca Delta, in Northern Canada, has shown the usefulness of employing new equipment to understand channel hydraulics in remote areas. A differential GPS system was used for accurate surveying work, and an Acoustic Doppler Profiler (ADP) was used to determine flow rates. Channel bank heights for an 81km distance upstream from Lake Athabasca were determined, as were river surface levels at medium discharge in the Athabasca River and its distributary channels. As many as 15 channel sections were surveyed per day with a boat-mounted ADP. For the same daily discharge value, cross-sectional average velocities in the main channel were found to be preserved at about the same value for a remarkably long distance in the final part of the delta, all the way to the lake. Comparison with old data shows a remarkably rapid rate of channel building. Flood magnitudes that cause bankfull flow conditions were found to change by a large factor from the head of the delta to the lake.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
