Hydrologic connectivity — wbt_hydrologic

This tool evaluates hydrologic connectivity within a DEM.

Usage

wbt_hydrologic_connectivity(
  dem,
  output1,
  output2,
  exponent = 1,
  threshold = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

dem: Name of the input DEM raster file; must be depressionless.
output1: Name of the output downslope unsaturated length (DUL) file.
output2: Name of the output upslope disconnected saturated area (UDSA) file.
exponent: Optional exponent parameter; default is 1.0.
threshold: Optional convergence threshold parameter, in grid cells; default is infinity.
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.

Value

Returns the tool text outputs.
