The subglacier

This section describes how to control PISM’s sub-models of subglacial processes: the basal strength, the subglacial hydrology, and bed deformation.

Two of these sections (Controlling basal strength and Parameterization of bed roughness in the SIA) can be thought of as parts of PISM’s stress balance model: they cover PISM’s treatment of basal boundary conditions: the former for stress balance models including longitudinal stresses, and the latter for the non-sliding SIA flow.
