MARC recordA theoretical determination of the characteristic equation of snow in the pendular regime / Elizabeth M. Morris, R.J. Kelly.
| Title: | A theoretical determination of the characteristic equation of snow in the pendular regime / Elizabeth M. Morris, R.J. Kelly. |
| Author(s): | Morris, Elizabeth M. Kelly, R. J. |
| Date: | 1990. |
| In: | Journal of Glaciology. (1990.), Vol. 36(123) (1990) |
| Abstract: | Recent mathematical models treat natural snowpack as mixture body consisting of solid ice grains, liquid water, and air/water vapour gas. This requires two independent constitutive equations for two independent volume fractions. So far, only one equation, power law relating liquid-water content to capillary pressure, has been suggested, by analogy with "characteristic" equation for liquid water in soils. Experimental data from drainage tests on snow columns may be used to determine characteristic equation for snow for relatively high water contents. However, method is not valid when water exists in isolated inclusions in snow, i.e. pendular. Here, theoretical method is used to derive two independent volume-fraction laws for snow in pendular regime. |
