Abstract
Pacific International Engineering has developed the Ship-Generated Hydrodynamics (SGH) computer model in order to predict the effects of deep-draft vessel traffic. The SGH model is comprised of two dynamically-coupled sub-models, one for the wake and one for the drawdown, which calculate vessel-generated water surface fluctuations, current velocities and wake transformation. The model is constructed to permit the use of complex channel geometry and bathymetry, realistic ship hull shapes and variable sailing lines, and employs an auto-calibration technique to ensure accurate wake generation. This advanced computer model has been used successfully and cost-effectively on a number of projects in Canada and the US. This paper describes the governing equations and structure of the SGH model, and its application to a problem on the St. Lawrence River near Sorel, Quebec.

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
