Seismic Bedload Transport on Mt. Rainier’s Glacial Rivers
The December 2025 atmospheric-river floods — analysis, review, and reproducible workflow
Preface
This book reports a study of bedload sediment transport inferred from seismic noise on the glacier-fed rivers draining Mt. Rainier, Washington, during the December 2025 Pacific Northwest atmospheric-river floods — and documents the analysis, review, and reproducible workflow behind it.
It is organized in three parts:
- Part I — Manuscript: the research paper (Introduction · Data & study area · Methods · Results · Discussion · Limitations · Conclusions).
- Part II — Reviews, critiques & development log: the physics & code review (including the corrected scaling baseline and the pipeline fixes), the literature & novelty positioning, and the reproducible workflow.
- Part III — References.
Headline result
Band-limited seismic power scales with discharge as P \propto Q^{b}. At the glacial-source station the exponent rises with frequency above the turbulent-flow baseline (b\approx 0.9 to 1.4) and decays downstream and away from the channel toward that baseline — the signature of a threshold-controlled bedload contribution confined to the near-source reach.
This is a working research compendium produced with substantial AI assistance. Part II preserves the review and development log; items flagged 💬 there are open questions and reviewer-defense notes, not settled claims.
