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:
NULLwill use the value in WhiteboxTools settings, seewbt_wd()for details.- verbose_mode
Sets verbose mode. If verbose mode is
FALSE, tools will not print output messages. Default:NULLwill use the value in WhiteboxTools settings, seewbt_verbose()for details.- compress_rasters
Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default:
NULLwill use the value in WhiteboxTools settings, seewbt_compress_rasters()for details.- command_only
Return command that would be executed by
system()rather than running tool. Default:FALSE.
