Manning's 'n'

The determination of Manning's 'n' coefficients is an important part of setting up hydraulic models. The following documents are used to calculate and confirm Manning's 'n' coefficients for hydraulic models. The RHDS and Manning's 'n' form provide instruction on to use these documents.
