Modelling Seasonally Freezing Ground Conditions.

Abstract

This projects's aim is to model the spatial distribution of snowcover in areas experiencing seasonally frozen ground. SNOWM1, the model that is currently being developed is an attempt to mathematically model and thereby represent, the distribution of snow within a catchment over the snow season. Figure 1 is a graphical representation of the snowcover distribution over the snow season, which SNOWM1 will attempt to mathematically reproduce. Figure 1 considers a plane model slope the position and elevation of which are defined by the coordinates X, Y and Z. X and Z are the axes of rotation, for variations of slope angles and azimuths. The evolution in time of a snow profile at a given point (Xy/Yy) on the slope is shown along the T-axis (points 1,2 and 3). Snowprofile variation with elevation is demonstrated for any time, along the Y-axis (points 4,2 and 5). It is this situation, graphically demonstrated by figure 1, that, when applied to a catchment, the model SNOWM1 is being developed.
