Treatment of ice-shelf evolution combining flow and flexure

Abstract We develop a two-dimensional, plan-view formulation of ice-shelf flow and viscoelastic flexure. This combines, for the first time, shallow-shelf approximation horizontal (and shallow-stream on lubricated beds such as where ice rises rumples form), with treatment thin-plate demonstrate by performing two finite-element simulations: one relict pedestalled lake features that exist some debris-covered shelves due to strong heterogeneity in surface ablation, other rumpling grounding zone an rise. The proposed opens new venues investigate physical processes require coupling between longitudinal deformation vertical flexure, instance, effects melting supraglacial lakes shelves, interactions sea swell, many others.
