Record #80284:

Proposal for a constitutive equation of temperate firn / Walter Ambach, H. Eisner.

Title: Proposal for a constitutive equation of temperate firn / Walter Ambach, H. Eisner.
Author(s): Ambach, Walter.
Eisner, H.
Date: 1986.
In: Cold Regions Science and Technology. (1986.), Vol. 13(1) (1986)
Abstract: Derives equation from deformation measurements at firn pit 20 m deep. Analytical and numerical formulation passes over into Glen's flow law for ice at transition of firn to ice. Basis of analysis is determination of shear strain-rate from tilt rate of pit axis, considering longitudinal and vertical strain-rates, compressibility of firn and triaxial pit deformation.
Notes:

Cold Regions Science and Technology. Vol. 13(1) :1-9 (1986).

Keywords: 551.578.463 -- Snow cover, firnification.
E10 -- Glaciology: snow and avalanches.
