520 3# ‡aExact description of steady downhill flow of viscous ice stream across no-slip to free-slip transition in basal boundary condition suggests ways in which such transitions might be detected by observations of ice-stream surface properties. Best expression of transition is in free-surface profile, which dips over point of transition and becomes horizontal far downstream. Streamwise velocity at surface shows gradual change across transition, in disagreement with earlier studies which suggest marked change. Basal shear stress and basal pressure exhibit singularitiesat point of transition. Confirms former singularity is likely point of strong basal erosion.
