Webb22 juni 2024 · The Shallow-Shelf Approximation (SSA) was developed to model ice shelves, where basal shear stress is zero and where longitudinal stresses dominate. The SSA is a vertically integrated (2D) model, with a depth-averaged ice velocity. Webb1. Angular unconformity: The strata below dip at an angle different from that of the beds above. Indicates that during the pause in deposition, a period of deformation (folding or tilting) occurred. 2. Disconformity: The beds above and below are parallel. The gap in the rock represents a period in which erosion rather than deposition occurred. 3. Webb5 nov. 2024 · We formulate steady, shallow ice sheet flow as an obstacle problem, the unknown being the ice upper surface and the obstacle being the underlying bedrock topography.
