The 5^th Steering Committee Meeting was held on the 8^th of January 2018 at the University of Exeter.

A method (under development) for including effect of debris on scour based on experimental data was introduced. Experiments on a single span arch for measuring hydrodynamic pressure were reviewed. Results on scour simulation at a single pier and arch bridge, carried out using OpenFOAM, were also presented and discussed. This was followed by a discussion & feedback session, by the steering committe, on results and delivering impact.
