ABSTRACT
An analytical solution to the surface flow rate of a steady state ice sheet has been compared to results from a finite difference model that employs the WIPP notation in order to validate that FLAC is an appropriate system for the study of glacial dynamics. An anisotropic flow law for polycrystalline aggregates with a single glide system is implemented via the WIPP notation by multiplying the flow parameter A for each finite difference element by a scalar term that represents the pervasiveness of the local crystallographic fabric. The anistropic model has been applied to a polar outlet glacier to determine the spatial distribution of the bulk crystallographic fabric within the ice mass.
