I recently had the pleasure of presenting in a webinar on channel roughness (here is a link to webinar video) for the Australian Water School’s training arm called ICE WaMR (International Centre of Excellence in Water Resources Management). My portion of the webinar was developed from my blog post on the Manning’s equations, which is how the ICE WarM webinar organizers found me!

The webinar is about an hour long, including Q&A, and provides a nice overview of the history, development and application of channel roughness for modelers (or “modellers”, spelled the Australian way). The webinar had over 500 registrants and nearly 300 computer connections. Below is a synopsis of the webinar from the event posting:

The empirical Manning equation is one of the most commonly applied approaches in water modelling. Where did it come from, what does it mean for your model, and what other options do you have?

Selecting a proper roughness coefficient is one of the most challenging and consequential steps of hydraulic modelling. Please join us for a discussion about the background of the Manning’s roughness coefficient along with tips, tricks, and pitfalls to look out for in selecting representative values for open channels, pipes, and more

The webinar included two other outstanding speakers in Chris Goodell and Krey Price. Their bios and links to their excellent blogs are below, along with some other useful links:

Chris Goodell, Kleinschmidt Associates
Chris is the Principal Consultant for Hydraulics and Hydrology at Kleinschmidt Associates. Chris specializes in water resources hydraulic engineering. He has a background in both hydraulic design and river engineering. His expertise includes hydraulic modeling, dam break studies, sediment transport, bridge and culvert design, inundation mapping, and software development/design.

Krey Price, Surface Water Solutions
Educated at the University of California at Berkeley, Krey is a civil engineer and project manager with international experience in water resources. He is engaged in computational modelling, engineering design, and project management for flood mitigation, mine rehabilitation, river and wetland restoration, stormwater management and catchment assessment projects.

Here is a short overview of the ICE WaRM:

ICE WaRM is recognised globally for leadership and innovation in collaborative approaches to capacity development for water management and sustainable economic development.

We provide a gateway to Australian, and international, expertise in education, training and research in water resources management, water sensitive cities and access to safe drinking water and sanitation. We are committed to working in partnership with development agencies, governments and the private sector for the progressive realisation of the Sustainable Development Goals.
