Accumulation of frazil ice along a river bend
Bibliographic record
Abstract
This paper discusses the role of transverse currents on frazil ice accumulation along a river bend. To this end, field observations of a frazil ice jam along the ShiYaoBu bend reach of the Yellow River, in China, and a model study in the laboratory were carried out. Field measurements of flow velocities verified that there are two transverse circulations under an ice cover. The characteristics of frazil ice accumulation along a river bend have been discussed. The laboratory model study shows that the transverse accumulation of frazil ice depends not only on the hydraulic variables, such as Froude number, but also on the central angle of the river bend (inclined to the entrance cross section). Equations describing the transverse accumulation of frazil ice along a bend have been established. The dependency of the accumulation thickness in the longitudinal direction on the Froude number and ice discharge has been derived.

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.
