Bridge abutments and superstructures can significantly contract floodwaters, causing severe sediment scour and threatening structural stability.
Large-scale lab experiments show scour patterns depend on deck submergence, abutment length, structure, and bed mobility, affecting scour depth, geometry, and location.
HEC-23 design criteria prevent embankment breaching but not channel erosion or abutment toe undercutting; improved scour predictors are needed for accurate sediment loss estimation. </aside>
