DESCRIPTION:Subglacial flooding\, typically caused when lake drainage rele
 ases large volumes of water beneath a glacier\, can have a significant imp
 act on the dynamics of the overlying ice. Existing drainage systems are co
 mpletely overwhelmed and the ice must deform to accommodate the water. I w
 ill discuss a simple elastic sheet model for ice which\, when combined wit
 h variation in basal topography or overlying ice thickness\, allows for ra
 pid transport of large volumes of water beneath the ice. I will then discu
 ss how this model can be combined with commonly used models for the viscou
 s flow of ice in order to understand how subglacial flooding impacts the f
 low of the overlying glacier.
