Method and provenance

Production method: A shared-velocity mixture model with mass-conserving melting uses an imposed release of 35.42 Mm³ containing 20% ice. Arrival windows and downstream stage records constrain comparisons within the tested scenarios.
Provenance: The version 2 title page identifies Hyoseok Park, Department of Physics, Chungnam National University, Daejeon, Republic of Korea. The previous University of Tsukuba attribution was incorrect.
Validation: Not Peer Reviewed
Uncertainty: Low effective resistance is supported within the adopted modelling scenarios. Revision does not establish zero yield strength or identify frictional melt as the unique flood mechanism.
Limitations: Source volume and ice fraction are input assumptions. Gauge-outage arrival windows are conditional. Model outputs are not observed flood-depth rasters. The code has an MIT licence, distinct from the article’s CC BY licence.
