Field Study on the Dissipation of Supersaturated Total Dissolved Gases in a Cascade Reservoir System
Bibliographic record
Abstract
Assessment of the dissipation of total dissolved gases (TDGs) is important in the downstream of hydropower facilities which often encounter TDG supersaturation. An analysis of the two consecutive spill events at the Peace River hydropower system, which includes the Bennett Dam and the Peace Canyon Dam, showed that the percent saturation of TDG and dissolved oxygen (DO) varied with spill rates, pre and post-spill conditions. The decay of TDG was comparatively slower than DO and the rates decreased with the drop of spill flows. For spill of 1,160 m3/s at the Peace Canyon Dam, the decay rate for TDG at the dam tailrace and at a distance 7 km downstream was found to be 0.005 and 0.0014 hr-1, respectively. A conceptual computational fluid dynamics model of the reservoir indicated that density driven currents could affect the TDG dissipation.

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.
