Calculate planform dimensions

Calculates planform dimensions (bend radius of curvature, meander wavelength, and meander belt width) for each bend and loop in the input `bankline_points` data frame.

planform(bankline_points)

Arguments

bankline_points

sf data frame; a `bankline_points` data structure used by the fluvgeo package.

Value

Returns a data frame of bends with the calculated planform dimensions.

Examples
