Escarpment

class fastscape.processes.Escarpment(*, x_left, x_right, elevation_left, elevation_right, shape, x)

Initialize surface topography as an escarpment separating two nearly flat surfaces.

The slope of the escarpment is uniform (linear interpolation between the two plateaus). Random perturbations are added to the elevation of each plateau.

x_left

Location of the scarp’s left limit on the x-axis

Variable properties:

type : variable
intent : in
dimensions : ()
static : True

Type:: attr.Attribute

x_right

Location of the scarp’s right limit on the x-axis

Variable properties:

type : variable
intent : in
dimensions : ()
static : True

Type:: attr.Attribute

elevation_left

Elevation on the left side of the scarp

Variable properties:

type : variable
intent : in
dimensions : ()

Type:: attr.Attribute

elevation_right

Elevation on the right side of the scarp

Variable properties:

type : variable
intent : in
dimensions : ()

Type:: attr.Attribute

shape

Nb. of grid nodes in (y, x)

Variable properties:

type : foreign
reference variable : UniformRectilinearGrid2D.shape
intent : in
dimensions : (‘shape_yx’,)

Type:: attr.Attribute

x

Grid x coordinate

Variable properties:

type : foreign
reference variable : UniformRectilinearGrid2D.x
intent : in
dimensions : (‘x’,)

Type:: attr.Attribute

elevation

Surface topography elevation

Variable properties:

type : foreign
reference variable : SurfaceTopography.elevation
intent : out
dimensions : (‘y’, ‘x’)

Type:: attr.Attribute
