Such events had not been previously documented in Canada. Rainstorms following five fires caused significant events in the Okanagan and Kootenay regions of the province, including the Okanagan Mountain Park, Cedar Hills, Kuskonook, Lamb Creek, and Ingersoll fires. Damage to residential property and infrastructure downstream of the fires occurred in three cases. Most of the damaging events were debris flows, although several large debris floods occurred on lower gradient streams. At four of the fires, the events were triggered by short-duration, high-intensity rainstorms. At the fifth fire, a long-duration, low-intensity rainfall triggered the events. In all cases, severe burns with water repellent soils were identified or suspected as contributing to the events. The debris flow and debris flood events described here illustrate three initiation mechanisms: runoff-triggered debris flows caused by erosion of channel bed and banks by critically high discharge; debris flows and floods caused by progressive sediment bulking of runoff with material eroded from headwater slopes; and landslide-triggered debris flows caused by a landslide that enters a steep channel. In the burned areas studied, the first mechanism is the most common, whereas in unburned forested landscapes in the region, the third mechanism is the most common.

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.
