Application of a hydrodynamic model in a freshwater delta using remote sensing
Bibliographic record
Abstract
The Peace-Athabasca delta (PAD) is located in the northern extreme of Alberta, Canada and is one of the world's largest freshwater inland deltas. Inland areas surrounding the main flow system comprise a myriad of small lakes and wetlands, of which a large percentage are hydrologically disconnected or perched at elevations higher than adjacent lakes or channels. This large, complex and dynamic ecosystem has undergone substantial changes over the last 25 years. The remoteness of this site, along with a shortage of hydrological and ecological information, has necessitated the development of innovative methods to assess these changes. These methods include the analysis of Landsat, Radarsat and SPOT satellite imagery for verification and calibration of a hydrodynamic model to observed flood conditions. This unique coupling of imagery and a hydrodynamic model provides key validation points and initial conditions for model runs. The results of the techniques outlined in this paper provide a starting point to assess changes produced by flow regulation and climatic change.

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.
