Abstract
A continuum model of a channelized, free-surface granular flow is developed to calculate the rate at which it expands into an initially grain-free region when lateral constraints are removed. The spreading is driven by cross-stream pressure gradients and resisted by basal drag. The boundary between the granular vacuum and the flowing grains is elucidated both in the near and far fields. © 2005 Taylor & Francis Group.
