Hydrogeophysical investigation for groundwater at the Dayspring Children's Village, South Africa
Bibliographic record
Abstract
Over the past 30 years, the water available in boreholes at the Dayspring Children's Village has slowly diminished to the point where the school's viability is threatened. In this same time period, a large stand of eucalyptus and yellow wattle trees has become well established. These trees are known to consume large quantities of water and we are investigating the effect of these trees on the local groundwater hydrology. Many types of geophysical and hydrological data—including gravity, magnetic, electrical resistivity, electromagnetic (EM) and seismic—are being acquired to understand the regional geology, seasonal changes and ultimately the impact of the trees on the local hydrology. Electrical resistivity data collected at the end of the dry season and at the end of the rainy season are used to define seasonal changes of a near-surface aquifer. By quantifying the effect of these trees on the hydrology, predictive recommendations on the benefits of tree removal can be made to government.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
