Glacier: a river of slowly moving ice
Change the snowline and watch ice thickness evolve through snowfall, melting and Glen-law deformation.
Try this
Raise the equilibrium line to increase melting. Compare the changing ice front and total volume.
The model and its limits
One-dimensional shallow-ice Glen flow with an elevation-dependent mass balance. One simulation second represents 0.4 years. Constant valley width, no calving or basal sliding.
Equations used in the module
Equations q = -(2/5) A (rho g)^3 H^5 (ds/dx)^3 dH/dt = balance - dq/dx
