Explanation of Manning's Roughness Exercise

Exercise Objective

To assess computation of Manning's roughness based on use of FGM terms and variables.

Exercise Explanation

1. Manning roughness is defined as n = (1.486 R2/3 S1/2) / u.
2. The data provided create the following equation: (1.46 3.52/3 0.0031/2) / 6.
3. Manning roughness is 0.031, similar to a winding natural Stream channel.
