Glaciers Hydrology Daren Blanck, MS

Glacier: a Flowing Stream of Ice Mountain Continental (Ice Sheets)

Snowfall vs Melting Zone of Accumulation Snowfall Exceeds Melting & Sublimation (Ablation) Excess Snow Turns to Ice & Flows Out Zone of Melting (Ablation) Ablation Exceeds Snowfall Melting Excess Made up by Ice Flowing in Terminus of Glacier Snowfall & Inflow = Ablation

Anatomy of a Glacier

Flow Glaciers flow due to Gravity and Internal deformation

Crevasse Diagrams

A Typical Glacial Advance and Retreat

As long as Accumulation = Ablation, the Glacier Front Remains Fixed

If Accumulation Exceeds Ablation, the Glacier Advances

If Ablation Exceeds Accumulation, the Glacier Retreats

Eventually, Material Trapped in the Ice Reaches the Terminus
