Influence of Catchment and Stream Characteristics on Suspended Solids and Phosphorus Concentrations Across an agriculturally Intensive Watershed in Southern Ontario
Bibliographic record
Abstract
The overall objective of this study is to determine the influence of landscape and hydrological characteristics on sub-catchment variability of total phosphorus (TP), soluble reactive phosphorus (SRP), the ratio of SRP and TP (SRP/TP), and total suspended solids (TSS). Fourteen longitudinal synoptic surveys were conducted for 13 sampling sites over a variety of flow conditions in the Innisfil Creek watershed located in southern Ontario. The surveys were split into baseflow and stormflow and partial least squares regression (PLSR) was used to analyze the relationship between watershed and hydrological characteristics, median concentrations of phosphorus, and TSS. The PLSR models indicate that buried tile drainage might be a major source of SRP in Innisfil Creek, while bank erosion is likely a dominant source of TSS. The results of this study can serve as the basis for future adaptive management experiments that seek to improve water quality in Innisfil Creek and beyond.

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.
