Effect of triangular corrugated beds on the hydraulic jump characteristics
Bibliographic record
Abstract
In this study, the hydraulic jump characteristics were studied experimentally over six triangular corrugated beds in a rectangular cross section flume. A total number of 42 tests were carried out for Froude numbers 6.1 to 13.1 in low stage of jump. In all tests, the main characteristics of hydraulic jump were measured. The results showed that the corrugated bed caused the conjugate depths of the jump and the hydraulic jump length to be reduced by 25% and 54.7%, respectively, compared to those of smooth bed. The obtained shear stress coefficient for corrugated bed is about 8.5 times of that for smooth bed. The effect of the relative corrugation heights on the jump characteristics was not found to be significant. Finally, results obtained from this study showed that the effect of the shape was almost insignificant. Furthermore, no specific corrugated sheet could be chosen to simultaneously reduce the tailwater depth and the jump length.

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.
