Shallow shelf approximation as a “sliding law” in a thermomechanically coupled ice sheet model
The shallow shelf approximation, a balance of membrane stresses for ice flow, is an effective
“sliding law” for ice sheet modeling. Our use of it as a sliding law becomes a standard model …

Seasonal changes in ice sheet motion due to melt water lubrication
IJ Hewitt - Earth and Planetary Science Letters, 2013 - Elsevier
A numerical model is used to calculate how the motion of an idealized ice-sheet margin is

Feedbacks between coupled subglacial hydrology and glacier dynamics
On most glaciers and ice sheet outlets the majority of motion is due to basal slip, a
combination of basal sliding and bed deformation. The importance of basal water in …
