Glacial erosion

Computer simulation of glacial erosion. The simulation was performed with the higher-order ice sheet model iSOSIA (Aarhus University, Denmark). Erosion operates by subglacial abrasion and quarrying. Both erosion processes depend on the basal sliding rate, which, in turn, varies with the stress and the melt water pressure at the glacier bed.
The eroded bedrock is entrained in the basal ice and used as abrasive tools.
The simulation shows how a fluvial catchment with graded river profiles and V-shaped valleys becomes a glacial landscape with overdeepened U-shaped troughs, hanging valleys and sharp-edged ridges. Essential for this development is the transverse shear stress of the viscous glacier ice.

Good job but technically, if I saw these valleys in an air photo, I would say there are non-glacial because of their v-shaped :)
