The Thermal Regime and Groundwater-Surface Water Exchange in a Sub-Alpine Headwater Stream
Bibliographic record
Abstract
Stream thermal regimes are critical to the stability of freshwater habitats. Groundwater plays an important role in controlling stream temperatures in mountain headwaters, where it makes up a considerable portion of discharge. This study investigated the controls on the thermal regime of a headwater stream, and the surrounding groundwater processes, in a catchment in Kananaskis Country, on the eastern slopes of the Canadian Rocky Mountains. Stream temperatures at the site are strongly influenced by the interactions between groundwater and an intermittent lake at higher elevation, with no surface water outflows. During precipitation events, the latent heat flux associated with melting of direct snowfall onto the water surface was responsible for rapid stream cooling. An increase in advective inputs from groundwater and hillslope pathways did not result in observed cooling of stream water during rainfall events. The overburden was determined to be an important conduit of water to the stream. A downstream thinning of the overburden was observed resulting in reduced groundwater contribution. The results from this study will assist water resource and fisheries managers in adapting to stream temperature changes under a warming climate.

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; both teacher heads agree on what is shown here.
