Assessment of the WP4-T Device for Measuring Total Suction
Bibliographic record
Abstract
Abstract Soil-water characteristic curves (SWCCs) play a key role in the determination of unsaturated soil property functions for use with predictive numerical models. Most studies on the soil-water characteristic curve have been limited to the desorption branch in the low suction range (i.e., less than 1500 kPa). There is limited measured data on desorption and adsorption branches (i.e., hysteresis effects) in the high suction range. The dew-point Water PotentiaMeter (i.e., WP4-T) is a device that has been introduced into the commercial market for measuring total suction in the high suction range. The WP4-T device can reduce the time and costs associated with suction measurements in the high suction range. The performance of the WP4-T was evaluated using experimental data measured on Regina clay and Botkin silt soils. Measurements of total suction using the WP4-T device were compared with vacuum desiccator results using a range of saturated salt solutions. The results showed that the WP4-T device provides excellent results in the high suction range branches of the SWCC.

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.
