river_slope: Compute the slope along the river channel

In flee-group/watershed: Tools for Watershed Delineation

Compute the slope along the river channel

Description

Computes the change in elevation from one reach to the next.

Usage

river_slope(x, dem)

Arguments

x	A river vector layer in sf format, e.g., output from vectorise_stream()
dem	A digital elevation model, preferably a terra::SpatRaster

Value

Vector of slopes, one per reach, map units (e.g., meters of drop per meter of stream)

Examples

    data(kamp_dem)
    x = delineate(kamp_dem)
    vect = vectorise_stream(x$stream, pixel_topology(x))
   vect$slope = river_slope(vect, kamp_dem)
