In reconstruction of past ice sheets a plastic approach is often used in order to get a quick estimate of the shape and thickness of an ice sheet. The basic in the model has been that the bottom shear stress is assumed constant along a flowline (Orowan, 1949). This gives a simple calculation scheme for an ice sheet profile with an arbitrary bed surface. The unit “force” that cause this bottom shear stress is popularly called “driving stress”.
