Groundwater flow systems in the Bengal Delta, Bangladesh, inferred from subsurface temperature readings
Bibliographic record
Abstract
Borehole temperatures were measured in observation wells to determine the temperature-depth profile, magnitude oftemperature and thermal gradient. The observed temperature profiles are classified into recharge and discharge types. Therecharge-type wells are located in the northern site of the study area. Meanwhile, discharge-type wells are found in thesouthern site of the study area. The 2-D cross-section of subsurface temperature shows that the shallow groundwater temperature in the southern discharge area is higher than that of the northern recharge area. The calculated temperature-depthprofiles for shallow wells show the recharge rate ranging from 0.04 to 1.35 m/year and discharge rate within the range of -0.2to -0.79 m/year. On the contrary, the recharge rate is 0.05 to 0.16 m/year and discharge rate -0.15 m/year for the deep well sites.The present study has revealed the existence of shallow and deep groundwater flow systems in Bengal Delta aquifers.

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.
