Abstract

fetched live from OpenAlex

The water balance performance of evapotranspirative landfill biocovers (ET-LBCs) under Canadian cold climate conditions is evaluated by constructing seven lysimeters at a field site in Alberta, Canada, and monitoring water balance for 1 year. Two granular media types (topsoil and compost mixture) and three types of vegetation (native grass species, alfalfa, and Japanese millet) were used. The results suggested that as plants became established, the average percolation as a percentage of water input [percolation ratio (PR)] decreased in all lysimeters. Between the lysimeters subjected to rainfall simulation events, the lysimeters with Japanese millet transmitted the lowest amount of percolation (10%–17%), followed by native grass species (23%–28%), and alfalfa (25%). Under the same vegetation coverage, lysimeters with a compost mixture transmitted lower or equal percolation compared with lysimeters with topsoil. Water balance predictions made using Hydrus-1D and commercial model SEEP/W were compared with water balance data from lysimeters over the growing season. The predictive capabilities of the models decreased under high intensity rainfall events and with the occurrence of preferential pathways associated with plant roots.

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.
