MODEL-PROTOTYPE COMPARISON OF BRIDGE-PIER SCOUR

QUALITATIVELY, THE PATTERNS OF SCOUR AROUND BRIDGE PIERS AND ABUTMENTS OBTAINED IN THE LABORATORY HAVE ALSO BEEN OBSERVED IN THE FIELD. MOREOVER, CERTAIN APPARENT ANOMALIES OF FIELD SCOUR HAVE BEEN RATIONALIZED ON THE BASIS OF THE CONCEPT OF SCOUR FORMULATED DURING THE LABORATORY STUDY. THE FIRST QUANTITATIVE COMPARISON OF SCOUR IN MODEL AND PROTOTYPE WAS THE LABORATORY STUDY OF A 1:12 MODEL OF THE SKUNK RIVER PIER. ALTHOUGH THE RESULTS OF THIS STUDY INDICATE THAT, AS A FIRST APPROXIMATION, THE DEPTHS OF SCOUR IN MODEL AND PROTOTYPE MIGHT BE RELATED SIMPLY BY THE GEOMETRIC RATIO, THE SINGLE SITE INVESTIGATED DOES NOT SUPPLY SUFFICIENT EVIDENCE FOR A GENERAL CONCLUSION. /AUTHOR/
