Detailed Description
The PISM minimal model has till, but water that exceeds the capacity of the till is not conserved. There is no model for lateral transport.
This is the minimum functional derived class. It updates till water thickness. It implements a version of the "undrained plastic bed" model of [Tulaczyketal2000b], but with non-conserved drainage.
This model can give no meaningful report on conservation errors.
This talk illustrates a "till-can" metaphor applicable to this model: http://www2.gi.alaska.edu/snowice/glaciers/iceflow/bueler-igs-fairbanks-june2012.pdf
