Abstract
Physical flow models are used to study parameters affecting the erodibility of rock in dam unlined spillways. Among the existing physical models, the parameters of joint orientation and of protrusion are the most studied. However, other rock mass parameters have an important contribution in the erosion mechanism, but they were given less attention in existing research, or when studied, mixed results were obtained. In addition, most of the models simulate rock mass considering a single block, which cannot simulate possible interactions between blocks. To address this problem, a scale model that simulates an existing spillway was built in a UQAC laboratory. This model is a 1:40 scale of the existing spillway and reproduces hydraulic conditions of the prototype. The physical model makes it possible to vary several rock mass parameters, such as joint orientation, joint opening, protrusion, block volume, as well as joint roughness, to evaluate their impact in the rock erosion process.

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
