A theory of glacial quarrying for landscape evolution models

2012.8.1 Numerical models are used commonly to study the topographic evolution of glacially eroded landscapes. These models are grounded on a power-law rule that relates bedrock erosion rate to either the sliding speed or discharge of glaciers. This rule, however, is poorly linked to the principal process of glacial erosion, quarrying, in which bedrock

Glacial quarrying: a simple theoretical model - Semantic

Glacial quarrying remains enigmatic despite being long recognized as a primary, perhaps the dominant, process by which glaciers erode bedrock. The rate-limiting process appears to be subglacial rock fracture due to ice-induced mechanical stresses.
