Analytical hydrological modelling of green roof technology on a watershed basis
Bibliographic record
Abstract
Urban stormwater design usually involves a continuous simulation model (CSM). A CSM can determine numerous scenarios and outputs implementing best management practices (BMP). Green roof technology has recently emerged as a BMP. Although a CSM is accurate, an alternative type of model can be used for preliminary planning stages. Based on statistics, analytical modelling does not involve complex computer simulations and is appropriate at planning stages. This applied study calibrated an analytical model using outputs from a CSM created for the highland creek watershed in Southern Ontario. The analytical model predicted total runoff volume and runoff volume reduction (from green roof technology) within 0.6-6% and 4-8% respectively. Runoff reduction from other research has been found in the range of 1-12%. Analytical tools combined with the Unit Response Function (URF) method can easily be changed for any watershed and highlights the usefulness for predicting runoff on a volumetric basis for watersheds.

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.
