Abstract
Computer models to simulate the mass balance-driven flow of valley glaciers, of ice caps and of ice sheets are now highly developed and contribute to our understanding of glacial history and of the rates of change of ice volume and sea level that would attend a deglacial future. Such models aim to represent the dynamics of glacial ice, yet, because they span a large range of length scales, they differ in the physical processes that are taken to be significant. Although glaciation models at the scale of valley glacier and of continental ice sheets have received considerable attention, the challenge of developing models that are suitable for examining regional-scale glaciation, as in the Canadian Cordillera, Arctic Archipelago, the European Alps and the Himalaya, remains largely unexplored. The heart of the difficulty is that ice cap and ice sheet models cannot resolve the individual glaciers that populate such regions, whereas valley glacier models, which have the required resolution, focus on individual glaciers rather than on large assemblages of them. In this presentation we examine approaches and trade-offs for accurate and efficient modelling of glacier assemblages.
