Creates a cross-section plot for an open channel

This function plots a cross-section of a (trapezoid, rectangle, triangle), shaded as filled to the level indicated by the values passed to it.

Usage

xc_trap(y = NULL, b = NULL, m = NULL, units = c("SI", "Eng"))

y: water depth [\(m\) or \(ft\)]
b: bottom width [\(m\) or \(ft\)]
m: side slope (H:1)
units: character vector that contains the system of units [options are SI for International System of Units and Eng for English (US customary) units.
