class TwoLithologyErosionModel

Two Lithology Erosion Model

Base class for common functions of terrainbento models with two lithologies.

The TwoLithologyErosionModel is a base class that contains all of the functionality shared by the terrainbento models that have two lithologies.

class TwoLithologyErosionModel(clock, grid, m_sp=0.5, n_sp=1.0, water_erodibility_lower=0.0001, water_erodibility_upper=0.001, regolith_transport_parameter=0.1, contact_zone__width=1.0, **kwargs)

Bases: terrainbento.base_class.erosion_model.ErosionModel

Base class for two lithology terrainbento models.

A TwoLithologyErosionModel inherits from ErosionModel and provides functionality needed by all models with two lithologies.

This is a base class that handles setting up common parameters and the contact zone elevation.

The following at-node fields must be specified in the grid:

• topographic__elevation

• lithology_contact__elevation

__init__(clock, grid, m_sp=0.5, n_sp=1.0, water_erodibility_lower=0.0001, water_erodibility_upper=0.001, regolith_transport_parameter=0.1, contact_zone__width=1.0, **kwargs)

Parameters

• clock (terrainbento Clock instance) –

• grid (landlab model grid instance) – The grid must have all required fields.

• **kwargs – Keyword arguments to pass to ErosionModel. Importantly these arguments specify the precipitator and the runoff generator that control the generation of surface water discharge (\(Q\)).

Examples

This model is a base class and is not designed to be run on its own. We recommend that you look at the terrainbento tutorials for examples of usage.
