sequent_depth  R Documentation 
This function solves the Momentum equation for water flow in an open channel with a trapezoidal shape and determines the sequent (conjugate) depth. This is the flow depth either upstream or downstream of a hydraulic jump, whichever is not provided as input.

Q 
numeric vector that contains the flow rate [ 
b 
numeric vector that contains the channel bottom width [ 
y 
numeric vector that contains the water depth [ 
m 
numeric vector that contains the side slope of the channel (m:1 H:V) [unitless] 
units 
character vector that contains the system of units [options are

ret_units 
If set to TRUE the value(s) returned are of class 
The Momentum equation for open channel flow conditions in a trapezoidal channel:
M = \frac{by^2}{2}+\frac{my^3}{3}+\frac{Q^2}{gy\left(b+my\right)}
where C
is 1.0 for SI units and 1.49 for Eng (U.S. Customary) units.
The momentum function is assumed to be the same on both sides of a hydraulic
jump, allowing the determination of the sequent depth.
Returns a list including:
y  input depth
y_seq  sequent depth
yc  critical depth
Fr  Froude number for input depth
Fr_seq  Froude number for sequent depth
E  specific energy for input depth
E_seq  specific energy for sequent depth
