Abstract

fetched live from OpenAlex

Because of land subsidence in Nantong City caused by aquifer pumping, studies have been undertaken using a 3D groundwater flow model linked to a 1D land subsidence model to optimize the rates and distribution of abstraction. Model results to the end of 2022 show that the current pumping regime will cause subsidence rates to exceed established control targets by over 40% locally. However, a radical redistribution of pumping wells including the greater use of shallower aquifers will potentially allow annual yields to be increased threefold to around 128 × 10 6 m 3 without exceeding those targets. The results of this work have important implications for the sustainable development of groundwater resources in Nantong City and demonstrate the considerable benefits of modelling for proactive aquifer management and protection against subsidence.

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.

Teacher imitation

Not 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.
