Sliding, Drainage and Subglacial Geomorphology

Complex processes occur at the base of glaciers and ice sheets that influence their flow and hydrological behaviour and determine the landforms left behind by glaciation. This chapter considers mathematical models of basal sliding, subglacial water drainage and till deformation, and introduces various subglacial landforms due to the interaction of ice, water and sediment. The treatment extends to models of large-scale phenomena including glacier outburst floods and glacier surges.
