- W2093067815 abstract "Basal shear stress and sediment strength associated with the development of glacial flutes exposed during the 20th century in the Saskatchewan Glacier Valley Alberta, Canada, were determined by comparing reconstructed ice thicknesses, basal shear stresses, and field properties of sediments with the morphologically similar Kiwa Glacier Valley, British Columbia, Canada, where flutes are absent. Reconstructed subglacial conditions in these two valleys were compared to understand why flutes were developed in the former and not the latter. Using an existing topographic map of each glacier, equations for a series of longitudinal profile lines were determined to represent the existing ice surface. A previous ice surface, identified by trimlines along the valley walls, was reconstructed by applying the equations of longitudinal profile lines from the existing ice surface to a previous terminus between 5 and 10 km downvalley. After subtracting the elevation of the land surface (determined from topographic maps) from the reconstructed glacier surface, and calculating former ice surface slope, ice thickness and basal shear stress distributions were determined. Sediment texture and the location of flutes on a morainal topographic high, downglacier from a proglacial lake basin, allowed high porewater pressures to develop as glaciers extended to terminus positions in the Saskatchewan Glacier Valley. Sediment strength was reduced sufficiently below values of reconstructed shear stress plots to allow deformation creating flutes. The absence of a similar topographic high and different sediment textural characteristics in the Kiwa Glacier Valley resulted in lower porewater pressures and consequently less reduction in sediment strength preventing the development of glacial flutes despite higher shear stress values here. Results indicate that the degree to which sediment characteristics and porewater pressure allow reduction of subglacial sediment strength relative to basal shear stress is important in determining conditions when flutes may develop." @default.
