City of Calgary catch basin performance study
Bibliographic record
Abstract
This report provides catch basin inflows for five catch basin inlet configurations and four curb cut configurations at six grades ranging from 0.5 - 10.0% and cross-slopes of 0.0, 2.0 and 4.0%. Catch basin inflow rating curves were developed by testing a mock-up of a roadway at the Ocean, Coastal and River Engineering Research Centre of the National Research Council of Canada. Water flows ranging from 0.0002 - 0.39 m³/s were delivered to a model roadway to quantify the conveyance of the catch basin inlets for various roadway grades and cross-slopes. The report covers a review of the experimental setup, including details on the model roadway that was used to perform the tests. A review of the instrumentation used and the measurements performed in this work follows. The five catch basin inlet configurations and four curb cut configurations used in the study were examined. A preliminary analysis including an assessment of experimental uncertainties was performed. The detailed results from each of the five catch basin inlet combinations and four curb cut combinations were provided. Finally, a comparison of the performance of the drainage solutions covered in this report is performed.

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.
