conveyance {rivr}

Channel conveyance

Description

Calculate the channel conveyance.

Usage

conveyance(n, A, R, Cm)

Arguments

n

Manning's roughness coefficient (dimensionless).

A

Flow area [L^2].

R

Hydraulic radius [L].

Cm

Unit conversion coefficient for Manning's equation. For SI units, Cm = 1.

Details

Channel conveyance is routinely calculated in numerical solutions of steady, gradually-varied and unsteady flows. This function is used extensively by internal procedures and is made accessible to the user for convenience.

Value

The channel conveyance.
