Air Permeability as a Textural Indicator of Snow
Abstract Two air-permeability devices were developed and measurements were made to study the relationship between air permeability and structure of different snow types. Permeabilities varied both with position and direction in the snow-pack, and changed with time as metamorphic changes occurred. A...

Abstract Two air-permeability devices were developed and measurements were made to study the relationship between air permeability and structure of different snow types.
