Abstract
As part of a larger experimental program on dam breaching, this paper presents experimental results for a series of breach tests conducted on homogeneous non-cohesive embankments under several initial breach conditions. The initial conditions utilized different geometries including a V-notch cut into the crest of the embankment, which is typical of a number of previous experimental studies, as well as the more realistic mechanisms of overtopping over a flat crest, and the novel breach overtopping mechanism of simulating a crater caused by an explosive blast. The relative failure rates of each of the three initial breach geometries were compared against each other, as well as against previous experimental studies. It was found that the breach initiation mechanism has a strong influence on the time required for the breach to progress to failure. Based on the experimental results, a four-stage breach process is proposed to describe breach morphology and outflow.

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
