Abstract
Currently, the Preissmann slot model still enjoys popularity in modelling the transition between free-surface and fully pressurised flows in tail-race tunnels. However a fully dynamic and transient modelling technique is needed to predict the surge front location and velocity, the pressure rise in the full flow zone and the water depth change in the free-surface zone. In this paper, the transient flow is modelled and only one surge front is considered. Three 1 -D models, which differ from each other by the computational method used to calculate either the free-surface or the full flow conditions, have been developed and applied successfully to both laboratory and field data. Predictions have been compared to measurements and good agreement found. Comparison between the three fully dynamic models was done and selective criteria were forwarded.

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 it
