Evolution of topography, basal friction and surface velocities during the quiescent phase. a Evolution of the glacier geometry in time. Inset: the prescribed surface mass balance (SMB) is a function of elevation, here plotted as a function of x using the initial glacier geometry. b Evolution of the state parameter θ. Inset: the peak friction coefficient \(C^ \ast = C\frac{{\sigma _{\mathrm{N}}}}{{\sigma _n}}\) (details in Supplementary Information) as a function of x. c Evolution of surface velocity. Simulation using q = 1.5 and dc = 1.5 m
