WebGlaciers flow primarily because the ice within them deforms under the influence of gravity. Glacier flow is achieved by three mechanisms: internal deformation, basal sliding, and subglacial bed deformation (Figure 7).Internal deformation is achieved by the processes of ice creep, large-scale folding, and faulting.

Subhourly measurements of bed deformation, bed shear strength, subglacial water pressure, and surface speed at Storglaciären, a glacier in northern Sweden, showed that the shear-strain rates of the bed decrease during periods of high … nothe fort gardens
