normal_depth: Normal Depth Calculation

In rchlumsk/rcr: River Computations in R

Description

Calculates the normal depth for a given cross-section using the Manning's equation.

Usage

normal_depth(xs, Q, S, init_WSL = NA, options)

Arguments

xs	cross-section of object class xsection
Q	flow value through cross-section (m3/s)
S	bed slope in cross-section, typically supplied as part of a boundary condition
init_WSL	initial water surface level provided to initialize calculation
options	object of class rcr_options with options and constants for hydraulic calculations

Value

WSL	Water surface elevation

bankfull_flow to estimate the flow through the cross section using Manning's equation

flow_area to calculate the flow area in cross-section for given segments

The Manning's n used in the calculation of the normal depth is calculated as a composite Manning's n, weighted using the wetted pereimeter of the left overbank, main channel, and right overbank.
