Groundwater and Surface-Water Relations in the Willamette Valley, Oregon
Bibliographic record
Abstract
This chapter describes the geologic framework of regional groundwater flow in the Willamette Valley, a conceptual model of the regional groundwater flow system, the results of cross-sectional numerical simulation of groundwater flow, and discusses implications for surface-water quality. This work was part of a comprehensive hydrogeologic investigation of the Puget-Willamette Lowland in Oregon, Washington, and British Columbia, Canada, conducted as part of the US Geological Survey Regional Aquifer-System Analysis program. The Willamette River drainage basin lies between the crests of the Cascade and Coast Ranges in western Oregon, encompassing approximately 11,500 mi2. The particle-tracking program calculates and records the paths of hypothetical particles of water as they move through the simulated system. The main source of groundwater recharge to the regional flow system is precipitation onto the valley floor and the Columbia River Basalt uplands in and around the valley. Most groundwater flow occurs in the Willamette aquifer and the overlying Willamette Silt.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
