Spatial Hydrology functions
Description
These functions perform spatial analyses important in hydrology. All
of the functions with the prefix ch_wbt require the installation of the
package Whitebox. The functions include:
- ch_wbt_removesinks
Removes sinks from a DEM by deepening drainage network
- ch_wbt_fillsinks
Removes sinks from a DEM by filling them
- ch_wbt_catchment
Generates catchment boundaries for a conditioned DEM based on specified points of interest
- ch_wbt_channels
Generates a drainage network from DEM
- ch_wbt_flow_accumulation
Accumulates flows downstream in a cathcment
- ch_wbt_flow_direction
Calculated flow directions for each cell in DEM
- ch_wbt_pourpoints
Snaps pour points to channel
- ch_wbt_catchment_onestep
Performs all catchment delineations in a single function
- ch_contours
Creates contour lines from DEM
- ch_checkcatchment
Provides a simple map to check the outputs from ch_saga_catchment
- ch_checkchannels
Provides a simple map to check the outputs from ch_saga_channels
- ch_volcano_raster
Returns a raster object of land surface elevations
