get_roughness: Get roughness value prediction

In mikejohnson51/FloodMapping: Map Flood extents using HAND and the National Water Model

Description

This function querys a REST API serving the Gradient Boosting machine learning model developed in the in-review paper:

Johnson, J.M., Eyelade D., Clarke K.C, Singh-Mohudpur, J. (2021) “Characterizing Reach-level Empirical Roughness Along the National Hydrography Network: Developing DEM-based Synthetic Rating Curves.”

Usage

get_roughness(pathlength, arbolatesu, lengthkm, areasqkm, slope)

Arguments

pathlength	The distance from the flowline outlet to the end of the network along the main network path
arbolatesu	Arbolate sum: the cumulative length of the upstream drainage network (mainstem and tributaries) from the outlet of the catchment
lengthkm	Length of a flowline in kilometers
areasqkm	Drainage area in km^2
slope	The longitudinal slope.

Value

A roughness value
