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"))
Arguments
- 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 andEng
for English (US customary) units.
Examples
# Draw a cross-section with depth 1, width 2, side slope 3:1 (H:V)
xc_trap(y = 1.0, b = 2.0, m = 3.0, units = "SI")
