ICE FLOW OVER BEDROCK PERTURBATIONS
The use of well known simple periodic solutions of the two-dimensional biharmonic stress equation for studying the flow over undulations of an ice mass of small surface slope is examined. The model considered is one in which most of the shear (deformation or sliding) takes place near the base and th...
