Draw the initial geometry of a river corridor.
Arguments
- river
A simple feature geometry representing the river
- method
The method employed to draw the initial river corridor:
"buffer": add a fixed buffer region to the river geometry (see
river_buffer()
)"valley" (default): use the river valley boundary, as estimated from the provided digital elevation model (DEM, see
river_valley()
)
- buffer
Buffer region to add to the river geometry (only used if
initial_method
is"buffer"
)- dem
Digital elevation model (DEM) of the region (only used if
initial_method
is"valley"
)- bbox
Bounding box defining the extent of the area of interest
