Metadata

Also known as
Model type Tool
Model part of larger framework LandLab
Incorporated models or components:
Spatial dimensions 3D
Spatial extent Continental, Regional-Scale, Landscape-Scale, Watershed-Scale
Model domain Terrestrial
One-line model description Create a Lithology object with different properties
Extended model description A Lithology is a three dimensional representation of material operated on by Landlab components. Material can be removed through erosion or added to through deposition. Rock types can have multiple attributes (e.g. age, erodibility or other parameter values, etc).
Keywords:

lithology, erodibility, geology,

Describe input parameters grid : Landlab ModelGrid

thicknesses : ndarray of shape `(n_layers, )` or `(n_layers, n_nodes)`
Values of layer thicknesses from surface to depth. Layers do not have to have constant thickness. Layer thickness can be zero, though the entirety of Lithology must have non-zero thickness.

ids : ndarray of shape `(n_layers, )` or `(n_layers, n_nodes)`
Values of rock type IDs corresponding to each layer specified in **thicknesses**. A single layer may have multiple rock types if specified by the user

attrs : dict
Rock type property dictionary. See class docstring for example of required format.

layer_type : str, optional
Type of Landlab layers object used to store the layers. If MaterialLayers (default) is specified, then erosion removes material and does not create a layer of thickness zero. If EventLayers is used, then erosion removes material and creates layers of thickness zero. Thus, EventLayers may be appropriate if the user is interested in chronostratigraphy.

dz_advection : float, `(n_nodes, )` shape array, or at-node field array optional
Change in rock elevation due to advection by some external process. This can be changed using the property setter. Dimensions are in length, not length per time.

rock_id : value or `(n_nodes, )` shape array, optional
Rock type id for new material if deposited. This can be changed using the property setter.
