Timothy T. Creyts, Garry K. C. Clarke and Michael Church Evolution of subglacial overdeepenings in response to sediment redistribution and glaciohydraulic supercooling Journal of Geophysical Research: Earth Surface 118

Article first published online: 22 APR 2013 | DOI: 10.1002/jgrf.20033

Key Points

  • We model basal water flow and include erosion of the bed and freeze-on of ice
  • Sediment transport has a strong influence on subglacial water flow conditions
  • Overdeepenings evolve because of sediment transport rather than ice accretion
