Flow of a Valley Glacier with a Solid Friction Law
Abstract Friction on the bed is assumed to obey Coulomb’s law of solid friction in the presence of interstitial pressure (Lliboutry, 1968). According to this, the friction is a maximum at certain places in the bottom of the valley. Assuming Glen’s non-linear creep law, the steady-state flow of ice a...

| Summary: | Abstract Friction on the bed is assumed to obey Coulomb’s law of solid friction in the presence of interstitial pressure (Lliboutry, 1968). According to this, the friction is a maximum at certain places in the bottom of the valley. Assuming Glen’s non-linear creep law, the steady-state flow of ice along a regular cylindrical channel of parabolic section has been calculated. The results reproduce to high accuracy the distribution of velocity measured on the Athabasca Glacier (Raymond, 1971). |
