Abstract

This paper attempts to combine numerical experiments on subglacial groundwater flow with field data to elucidate the relationships and interactions between the subglacial hydrology and ice sheet behavior. The AA. try to determine bed areas with strong groundwater drainage potential under the last ice sheet in NW Poland and areas largely inactive hydrologically, and relate these areas to the locations of tunnel valleys. They also apply numerical modelling to estimate subglacial groundwater fluxes and relate them to the empirically estimated basal meltwater production rates to evaluate the likelihood of basal decoupling and regional-scale ice sheet instabilities. Methods used (2D Steady-state Vertical-slice Model, 3D Steady-state Model, 3D Transient Flow Model), results and discussion
