Computes river hierarchies for a HS object.

Computes river hierarchies from a routed river network.

river_hierarchy(river, type = "strahler", riverID = "riverID")

Arguments

river	An 'sf' linestring feature representing a river network.
type	Type hierarchy to compute. Currently only strahler stream order implemented.
riverID	A character string which specifies the name of the column in river containing unique river network identifiers. Defaults to "riverID".

Value

Returns the river network with added column with the selected river hierarchy.

Examples

if (FALSE) {
library(hydrostreamer)
library(dplyr)

# load data
data(river)

# without prior routing
river <- river_hierarchy(river, riverID="ID")

# with routed network
routed_river <- river_network(river, riverID = "ID") %>%
    river_hierarchy()
}
