A Dam Breach Model of Epic Proportions — Simulating the Glacial Lake Missoula Floods
Bibliographic record
Abstract
The Columbia River Gorge and the Scablands of Eastern Washington are just two of the incredibly stunning geologic features carved out by the great Missoula Floods approximately 10 to 40 thousand years ago. These floods of epic proportions were triggered by the "failure" of a massive glacial ice dam that impounded a lake about the same size as the Great Slave Lake in Canada. With the improvements of available GIS data and dam breach modeling capabilities in HEC-RAS, a hydrodynamic model was constructed of this enormous flood stretching from Eastern Montana to the Pacific Ocean. The results of this model shed light on some of the enormities of this flood event, specifically the magnitude of discharge, flow velocities, and inundation extents. In addition, the progression of the flood wave through Eastern Washington, the Columbia River Gorge, up the Willamette River Valley and out to the Pacific Ocean is demonstrated through GIS.

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; a candidate call from one teacher head, not a consensus.
