ABSTRACT - Hydraulics of Bridge Waterways

The presentation will begin with a brief review of the important 'sediment transport'-related considerations that may govern the selection of sites for bridge crossings of rivers. This will be followed by a description of the local scouring process at bridge openings, piers and abutment structures and an overview of related design procedures and scour protection measures. The presentation will conclude with a description of research performed at University of Ottawa on the impacts of 'lateral momentum transfer' (LMT) on the local scouring process at bridge abutments located near the junctions regions of compound-shaped river channels.
