Abstract
In the unsaturated or vadose zone (above the water table), measurements of field-saturated water flow parameters are typically obtained using various ring infil-trometer and borehole or well permeameter methods. In the saturated zone (below the water table), saturated water flow parameters are generally obtained at shallow depths using auger hole methods, and at greater depths using piezometer methods. The saturated and field-saturated water flow parameters include saturated and field-saturated hydraulic conductivity (Ks and Kfs), matric flux potential (^m), sorptivity (S), the macroscopic capillary length parameter (a*), the effective Green-Ampt wetting front pressure head (hf), and the air-entry and water-entry pressure heads (ha and hw). This chapter discusses ring or cylinder infiltrometers (Vadose Zone) that includes single-ring and double- or concentric-ring infiltrometers; pressure infiltrometer; and twin- or dual-ring and multiple-ring infiltrometers.

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.
