Impacts of Debris on Bridge Pier Scour
Waterborne debris (or drift) often accumulates on bridges during flood events. The effects can vary from minor flow constrictions to severe flow contraction resulting in significant bridge foundation scour. The results of National Cooperative Highway Research Program (NCHRP) Project 24-26, "Impacts of Debris on Bridge Pier Scour" represent a significant advance to predicting debris scour considering the variable geometry of debris clusters observed at bridge piers in the field. The study produced results on two related problems: predicting the accumulation characteristics of debris from widely varying source areas, and developing improved methods for quantifying the depth of scour at bridge piers. This paper highlights the observations from laboratory testing and the development of improved algorithms for predicting the depth of scour at debris-laden bridge piers.
