This award will support collaborative research between Dr. Joseph               Walder, Department of Geological Sciences, University of Washington             and Dr. Andrew Fowler, Mathematical Institute, Oxford University,               U.K.  Recent developments in glaciology have led to the recognition             that deformable glacier beds may play a significant, if not                     dominant, role in glacier dynamics.  Nonetheless, our understanding             of the interactions between glacier ice, rock debris at or near the             glacier sole, and subglacial meltwater remains incomplete.                                                                                                      The proposed research project will focus on aspects of the physics              of deformable glacier beds, particularly the links between                      subglacial hydrology, bed deformation, and glacier motion.  There               are three parts to the proposed theoretical work:  1) Modelling of              till movement over rough beds 2) Modelling the influence of ice                 penetration into subglacial sediments on deformation of such                    sediments and 3) Modelling stability of subglacial meltwater                    conduits on beds of deformable sediment.  Dr. Fowler has made                   significant contributions to theoretical geology in recent years                and his mathematical expertise will be valuable in pointing out                 approximate analytical techniques involved in the proposed                      research.  This project may lead to significant advances in                     understanding the physics of the complicated zone of interacting                ice, rock debris and meltwater at the soles of many glaciers.                   Because of the growing recognition by glaciologists that glacier                dynamics can be controlled by this complicated basal zone, research             on this topic is very timely and important.
