Using the Manning equation in hydraulic modelling

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.
