Bibliography: p. 166-176 ... : As glaciers retreat world-wide and ice-related geomorphological features disappear in response to climate change, the importance of understanding the repercussions of their melt on the hydrology and geomorphology of Arctic basins increases. This thesis focuses on the conceptual and numerical modelling of Fountain Glacier proglacial icing located on Bylot Island, Nunavut. Emphasis is given to the understanding of the mechanisms involved in its annual regeneration and the glaciological and hydro-physical conditions responsible for its perennial preservation. Although it is known that glacial icings strongly interact with and depend on their adjacent glacier, there is still a lack of understanding concerning temporal relationships, hydrological feeding mechanisms and the glaciological conditions involved in their perennial preservation. The study of air photos, satellite imagery, topographical and geophysical surveys, ice coring and time lapse photogrammetry allowed a comprehensive understanding of the icing's ...
