Floodplain Mannings - Photographic examples

[paul_ollett 0]

Hi All,

 

I’m searching around for references on Manning’s n guidance for floodplains (excluding the open channel) based on photographic examples. A couple of references I have with example photos (both online) are:

·         Brisbane City Council Natural Channel Design Guidelines (Nov 2003 – Appendix C Mannings n)

·         Guide for Selecting Manning's Roughness Coefficients for Natural Channels and Flood Plains (reproduced over the past 40 years by a number of US agencies incl. Geological Survey and Department of Transportation)

I wanted to ask if anyone has come across other guidelines based on organised photos?

 

Many thanks

Paul.
