Dynamic Modeling of Real-Time Control of Combined Sewer Systems with Radial Gates and Siphon Weirs
Bibliographic record
Abstract
New code developed for radial gates and siphon-weirs is suitable for handling unsteady flow conditions occurring in real sewer systems. RGEXTRA.l\1 is described in two other chapters in this book (James and Young, 200la, b) and includes all features ofEXTRAN, which simulates branched or looped systems, backwater effects, surcharge, flow reversal and flow transfers by orifices, weirs and pumps. RGEXTRAN makes provision for dynamic control of radial gates (or other gate types) based on flow conditions at remote locations in the sewer system. This allows the model to be used for optimizing a combined sewer system operation by fully utilizing all available storage and conveyance capacity in the existing facilities. The dynamic radial gate code may also be used for analyzing system optimization in a real-time mode. The program is applied to the combined sewer system in Vancouver, British Columbia. Verification tests demonstrated that the new program accurately represents the operation and hydraulics of the dynamic radial gates and siphon-weirs found in the system.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
