Qin flow accumulation

Description

Calculates Qin et al. (2007) flow accumulation.

Usage

wbt_qin_flow_accumulation(
  dem,
  output,
  out_type = "specific contributing area",
  exponent = 10,
  max_slope = 45,
  threshold = NULL,
  log = FALSE,
  clip = FALSE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

`dem`	Name of the input DEM raster file; must be depressionless.
`output`	Name of the output raster file.
`out_type`	Output type; one of 'cells', 'specific contributing area' (default), and 'catchment area'.
`exponent`	Optional upper-bound exponent parameter; default is 10.0.
`max_slope`	Optional upper-bound slope parameter, in degrees (0-90); default is 45.0.
`threshold`	Optional convergence threshold parameter, in grid cells; default is infinity.
`log`	Log-transform the output values?.
`clip`	Optional flag to request clipping the display max by 1 percent.
`wd`	Changes the working directory. Default: `NULL` will use the value in WhiteboxTools settings, see `wbt_wd()` for details.
`verbose_mode`	Sets verbose mode. If verbose mode is `FALSE`, tools will not print output messages. Default: `NULL` will use the value in WhiteboxTools settings, see `wbt_verbose()` for details.
`compress_rasters`	Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: `NULL` will use the value in WhiteboxTools settings, see `wbt_compress_rasters()` for details.
`command_only`	Return command that would be executed by `system()` rather than running tool. Default: `FALSE`.
