Grounding line movement and ice shelf buttressing in marine ice sheets (2009, methodology): “Details are found in the work of Schoof [2007a], but briefly, if variables are scaled with the assumption that, over most of the grounded domain, the dominant balance is between driving force and basal friction, the nondimensionalized equations are”
Marine ice-sheet dynamics. Part 1. The case of rapid sliding (2007, background): “This could change the boundary-layer problem significantly, and an important effect then to take into account is that rapid sliding may in fact be poorly described by a power law, as assumed in this paper, and may more closely follow a Coulomb-type friction law (Iverson et al. 1999; Tulaczyk 1999; ”

Shallow shelf approximation as a “sliding law” in a thermomechanically coupled ice sheet model (2008, methodology): “Furthermore these quantities (temperature and basal water) must evolve if modeled ice streams are to exhibit the observed energy-balance-dependent behavior actually seen [Raymond , 2000; Schoof , 2004].”
