Abstract / Description of output

This paper uses a Geographical Information System (GIS) to develop a rule-based model of the effect of snow drifting on glacier growth in the Cairngorm Mountains, Scotland during the Younger Dryas interval. We develop a qualitative model of snow drift that uses a number of simple heuristics to generate a map of relative accumulation at a 50-m resolution over the massif. Relative susceptibility to snow drifting is then compared for a number of different zones under varying wind directions. We conclude that, under the conditions tested in our model, glaciation of the Cairngorms during the Younger Dryas was confined to the high corries and that the pattern of snow drifting suggested by our model points to dominant southerly winds.
