Abstract

Trough valley with stepped longitudinal profils and corries are common features of glaciated terrain. An ice sheet and glacier are modelled as a layer of a very viscous incompressible fluid flowing down an inclined bed. The rate of erosion is assumed to be determined by the basal shear stress. A stability analysis shows that the short-scale transverse perturbations are stable while the long-wave transverse perturbations are unstable. The analysis also shows that the longitudinal perturbations propagate up the bed with velocities that are different for the perturbations of different spatial scales
