Abstract:

The primary goal of this study was to validate the shallow snow mobility model. As previously mentioned, this model is based on theoretical relationships and empirical expressions developed in the past, and a large, but scattered, data base. Since the shallow snow model has not appeared in the literature in the past, we begin by describing the approach used in version 1.0 SSM1.0 for predicting mobility. The two principal quantities that govern mobility are traction and motion resistance. Commonly, two types of traction net and gross and two types of motion resistance internal and external are identified.
