Groundwater conditions beneath beaches of Lake Huron, Ontario, Canada
Bibliographic record
Abstract
Groundwater flow conditions below beaches of Lake Huron have been examined at eight sites. Groundwater below beaches flows towards the lake throughout the year. However, water table conditions vary between beaches with a shallow water table (< 1 m) and beaches with a deep water table (> 2 m). Where the water table is deep, the water table across a beach will rise and fall proportionally to fluctuations in lake levels. The hydraulic gradient is essentially linear across a beach. Beaches with a shallow water table exhibit very little change in the elevation of the water table over time, do not fluctuate proportionally with lake level changes, and have a break in the hydraulic gradient at ∼ 20 m from shore. Long term and season fluctuations in the surface of Lake Huron will change the elevation and location of the groundwater discharge area, resulting in the water table beneath the entire beach where the water table is deep to rise and fall proportionally and maintaining essentially the same hydraulic gradient. However, fluctuations in the lake levels have little impact on water table conditions at beaches where the water table is shallow.

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.
