Breaches all of the depressions in a DEM using Lindsay's (2016) algorithm. This should be preferred over depression filling in most cases.

Usage

wbt_breach_depressions(
  dem,
  output,
  max_depth = NULL,
  max_length = NULL,
  flat_increment = NULL,
  fill_pits = FALSE,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

dem

Input raster DEM file.

output

Output raster file.

max_depth

Optional maximum breach depth (default is Inf).

max_length

Optional maximum breach channel length (in grid cells; default is Inf).

flat_increment

Optional elevation increment applied to flat areas.

fill_pits

Optional flag indicating whether to fill single-cell pits.

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.
