Abstract
Borehole ground penetrating radar (GPR) measurements of water content within the unsaturated zone were performed during infiltration experiments using both a uniform and point source of water at the soil surface. Horizontal GPR antenna access tubes were installed at a depth of 1 m to measure the water content within the horizontal plane underlying the surface water sources. The zero offset profile and multiple offset gather modes of data collection were used to produce velocity profiles and tomograms that were converted to water content. Time domain reflectometry (TDR) probes provided near-surface measurements of water content to complement the deeper borehole GPR data. For the point source, the water content tomograms and profiles showed that the zone of increased water content was restricted to a 1 m diameter zone, centered below the point source. For the uniform source, significant variability in water content within the studied area was observed possible due to preferential flow of water through the soil profile.

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 it
