Book Description
Snow is a porous. permeable aggregate of ice grains. The grains can be predominantly single crystals or close groupings of several crystals. The pores are filled with air and water vapor. In wet snow the grains are coated with liquid water. The characteristic property of snow is its inherent thermodynamic instability. Consequently most of the interesting physical parameters inevitably change with time. This process of change is called snow metamorphism.

Oversnow Transport
Author: Malcolm Mellor
Publisher:
ISBN:
Category : Trafficability
Languages : en
Pages : 104
Book Description
Present military concepts call for highly mobile units capable of rapid dispersal and efficient movement across country where no roads exist, and many current civilian engineering tasks require movement of men and materials long distances over roadless terrain. Oversnow transport is a particular aspect of the general problem of cross-country mobility, but the characteristics of snow-covered regions are such that special techniques and equipment are required for efficient operation. In order to fully understand the action of vehicles in snow and to formulate sound design criteria, it is necessary to develop a theory which permits quantitative analysis of trafficability problems. For practical purposes, vehicle evaluation is at present made from the results of relatively simple field tests which give drawbar pull as their main indicator. The best practical evaluations are made by observing the operational capabilities of vehicles in various types of snow.

Spread Footing Foundations on Snow
Author: Sherwood C. Reed
Publisher:
ISBN:
Category : Foundations
Languages : en
Pages : 54
Book Description
A series of nine spread footing tests was installed on snow at Camp Century, Greenland, in 1961 and continuously observed through the 1963 summer season. The influence of footing load, size and shape on settlement were investigated and the effects of the uncontrolled parameters temperature and snow density were recorded. (Author).
