Glacier Dynamics — This simulation uses a simplified shallow-ice approximation of Glen's flow law: ice velocity ∝ (ρgH sin α)³ × H. Ice thickness evolves via mass balance — accumulation above the Equilibrium Line Altitude (ELA) and ablation below it. Temperature raise shifts the ELA upward, shrinking the accumulation zone. Brown sediment (moraine) marks the farthest extent reached.
