Record #97321:

Water-pressure coupling of sliding and bed deformation: 1. Water system / Richard B. Alley.

Title: Water-pressure coupling of sliding and bed deformation: 1. Water system / Richard B. Alley.
Author(s): Alley, Richard B.
Date: 1989.
In: Journal of Glaciology. (1989.), Vol. 35(119) (1989)
Abstract: Analysis of likely behaviour of water system developed between ice and unconsolidated glacier bed suggests that, in absence of channelized sources of melt water, system will approximate film of varying thickness. Effective pressure in film of this nature will be proportional to basal shear stress but inversely proportional to fraction of bed occupied by film. These hypotheses allow calculation of sliding and bed-deformation velocities of glacier from water supply and basal shear stress, as discussed in second and third papers in this series.
