Abstract


Scour around bridges has been one of the most important research fields in the last few decades. Many equations for scour prediction have been reported in the literature. The validation of these equations became necessary. In this paper, 30 equations that estimate scour around bridge piers and abutments are validated against a wide base of experimental and filed data. For design purposes, the study recommends the best equations to be used in scour prediction at bridge piers and abutments. The limitations of each equation are presented. The best equations for scour prediction at bridge piers and abutments are identified. Also, the study indicates that some equations should not be used in scour prediction as they significantly overestimate the scour depth.
