Arguments

DEM

raster - Elevation. Path to a raster layer.

CHANNELS

raster - Channel Mask. Path to a raster layer.

MODEL

rasterDestination - Modelled Elevation. Path for new raster layer.

DIFF

rasterDestination - Elevation Difference. Path for new raster layer.

UPDATE

boolean - Update. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

KAPPA

number - Diffusivity (m2 / kyr). A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

DURATION

number - Simulation Time (kyr). A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

TIMESTEP

enum of ("(0) user defined", "(1) automatically") - Time Step. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

DTIME

number - Time Step (kyr). A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

...

further parameters passed to qgisprocess::qgis_run_algorithm()

.complete_output

logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.

.quiet

logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.

.messages

logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
