"Three areas were briefly investigated: 1) analysis of various formulations for scour around bridge piers, 2) ongoing Federal Highway Administration field studies of scour around bridge piers, and 3) recommendations for future research"--Technical report documentation p.
"A comprehensive state-of-the-art treatment of scour and bridge foundations - both a handy reference text and a manual for the practicing bridge designer."--Publisher.
Available theories and prediction formulas on scour at bridge waterways are reviewed. Formulas that offer potential for prediction of scour around bridge piers are compared by reducing each formula to a non-dimensional form that includes Froude Number, the ratio of scour depth to pier width, and the ratio of stage to pier width. A field study to gather data on scour and related variables is described. The study is aimed at collecting field data in order to furnish a basis on which to compare scour prediction formulas.
