Hydraulics : construction and project management
A full hydrological and hydraulics analysis at each of the viaduct river crossings was undertaken and evaluated to identify the potential impacts of the viaduct and to design remedial measures that would minimise the predicted hydraulic and environmental impacts. Both the short-term impacts associated with the construction phase and the resulting long-term conditions were assessed. The analyses focused on changes in river flood levels and erosion potential along the river channel and on scour at the viaduct piers and abutments.
