Determination of Aquifer Position Using Electric Geophysical Method
Bibliographic record
Abstract
Aquifer positions were determined by using Schlumberger electrode configuration to conduct Vertical Electrical Soundings in 67 communities within the study area. This study was carried out because of the presence of failed boreholes and manually dug wells in some of the Local Government Areas in the study area. More précis information relating to the exact location of aquifers is therefore needed for successful management of water resources in the area, in the face of dwindling availability of portable water, occasioned by failed boreholes and the need to carter for the increasing population of inhabitants of the area. Interpretation of data showed two to six geoelectric layers. Reflection coefficient and resistivity contrast values greater than 0.9 and 19 respectively, were obtained in some VES stations. Productive shallow and deep aquifer terrains were identified with depth of 60 m and 150 m respectively and resistivity range of 100.0-500.0 ?m for shallow aquifers and 1000-2500 ?m for deep aquifers, respectively. The lithologic materials for the aquifers were sand/sandstone and very coarsed grained sand/fractured basement, respectively. The above inference on lithology was constrained by borehole logs in the study area.

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.
