(2011), and then analyze any differences. To do so, we define model parameters that measure the contrast of a two-layer model. These will be perturbations in fluid, shear modulus, and density and will be defined as

The model consists of a combined Mohr–Coulomb and end‐cap yield surface in the gouge layer and allows compaction and dilatancy with undrained pore‐pressure changes. paisagens multifuncionais
