spec_energy_trap: Creates a specific energy diagram for a trapezoidal channel

Description

This function plots a specific energy diagram of a trapezoidal (including rectangle and triangle) channel, with annotation of critical depth and minimum specific energy

Usage

spec_energy_trap(
  Q = NULL,
  b = NULL,
  m = NULL,
  scale = 3,
  units = c("SI", "Eng")
)

Arguments

Q

flow rate

b

bottom width

m

side slope (H:1)

scale

multiplier (of yc) for plot scale (default is 3)

units

character vector that contains the system of units [options are SI for International System of Units and Eng for English (US customary) units. This is used for compatibility with iemisc package]

Value

a specific energy diagram

Examples

# NOT RUN {
# Draw a specific cross-section with flow 1, width 2, side slope 3:1 (H:V)
spec_energy_trap(Q = 1.0, b = 2.0, m = 3.0, scale = 4, units = "SI")
