Abstract

fetched live from OpenAlex

This paper provides an introduction to the role of groundwater in watersheds, presents an overview of groundwater resources in British Columbia, and reviews the potential effects of forest management activities (e.g., harvest operations, road building, reforestation, management of mountain pine beetle infestation) on groundwater hydrology. A regional-scale classification of hydrogeologic landscapes for British Columbia is outlined, integrating major physiographic, biogeoclimatic, and groundwater regions. The classification considers characteristics of climate, geology, aquifer type, and interaction with surface water in a generalized way, and summarizes broad-scale expectations about the groundwater hydrology in each hydrogeologic landscape category. In all of the landscapes, a rise in the water table can be expected to follow forest harvesting, though the magnitude and duration of this increase vary according to the area's geology and topography. In wet, steep watersheds, for example, shallow groundwater flow is likely to increase, in turn leading to the potential for increased runoff and decreased slope stability. Local-scale water table changes are often more apparent than those at the regional scale.

Not 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.
