Conductividad hidráulica en dos sitios del Valle Central de Costa Rica: análisis comparativo de tres metodologías de ensayo en la zona no saturada
Bibliographic record
Abstract
This article presents a comparative analysis of 15 hydraulic conductivity field tests performed in the vadose zone at two sites in Central Valley of Costa Rica, characterized by silt and sandy-silt soils. Conductivity tests included Guelph permeameter (GP), Porchet (PM) and Double Ring (DR) methods. All three methods indicates higher field saturated conductivity (Kfs) values at sandy-silt soils as expected. Calculated Kfs values show the same trend reported in various scientific publication were DR >PM>GP. Authors interpreted lower values of Kfs obtained for GP as the result of: consideration of capillarity effects in the mathematical formulation, and more importantly the effects of short periods of pre-saturation and monitoring, during execution of PM and DR tests.

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.
