Hydraulic Aspects of the Design of a Passive Methane Oxidation Biocover
Bibliographic record
Abstract
Passive methane oxidation biocovers (PMOB) have been recently proposed as a viable option for migration residual emissions. The efficiency of a PMOB depends on the degree of saturation, which controls the migration of molecular O2; a necessary element in the CH4 oxidation process. The evolution of the degree of saturation Sr is regulated by the unsaturated flow of moisture across the PMOB, which can only be describe with the water retention curve (WRC) and hydraulic conductivity function (k-fct) of the material. This paper discusses the reliability of laboratory-obtained WRCs as input parameter in the prediction of the hydraulic behavior of PMOBs in the field. Three WRC were determined based on field data and in the laboratory using a tension plate. The field data was obtained from an experimental PMOB constructed at St-Nicéphore landfill, Quebec, Canada, where tensiometers and water content probes were installed.

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.
